Microsoft Surface Go 2 review

The new upgraded Surface Laptop Go 2 is the new iteration of the affordable original Surface Laptop Go aimed to offer good performance at a lower price of under $1000. The new version is not anything vastly different from the original but it comes with much-needed upgrades.

microsoft surface go 2 laptop

The biggest and main upgrade is the CPU, the Surface Laptop Go 2 is packing now Intel Core i5 1135G7, an Intels 11th generation CPU that should increase battery life. The laptop is also coming with an improved WEB camera and the cheapest one comes now with 128GB of storage instead of 64GB. Price went up from $550 to $599 which is not a big increase considering what was upgraded.

The bad news of new models is that sadly they are still packing only 4GB of RAM, that's really not enough for most applications released in 2022 and the screen is having a relatively low resolution of 1536 X 1024.

Microsoft is still offering all the color variations as in its first offering but added as well a new Sage color that is muted green in tint.

When we look at hardware it seems a little weak but for this price, there is not much competition in the field, and after all this line of models is aimed to provide good performance for an affordable price. If you really need something better you will go with a standard Surface or MAC book instead.

The new laptops are available to pre-order at Best Buy and Microsoft’s online store, and they’ll start shipping on June 7.

Antivirus software review 2022

As we near the end of 2022 we look at the current best antivirus software for popular platforms, why they are the best, and why you should get them.

Avira, a great free Antivirus

Avira has been around a long time with its free antivirus version of the larger protection suite. It had its ups and downs but the latest versions are really great. With high-speed scans and low system impact, Avira antivirus is really one of the best free antivirus software currently on the market.

Avira screen

The software itself has also received UI & UX updates making it straightforward and easy to use. The virus scanning engine is the same as in paid version that ranks among the top engines in the world for this type of work. The package also gives you some great browser protection and a good firewall as well, there is really no excuse to skip on this if you want a free solution.

The only thing that we would say is not so great in Avira is reporting some false positives, sometimes even for MS updates, it is rare but it can happen.

Malwarebytes, a powerful Windows antivirus

Malwarebytes Premium is easy to use, simple antivirus solution that shies away from complicated UI, and simply put, it just works. Its scanning engine is well-known and places among the top and best in the world often finding some malware that other can miss.

malwarebytes screen

Another great thing is its integration with Windows itself, it is one of the rare applications that can and will work incredibly well beside your typical Windows protection tools so you can have both of them running at the same time.

Installation and running are really simple and every typical PC user will find it as easy as walking in the park. On the other hand, sadly system impact is a little high and it will have issues running on lower-end systems due to its memory requirements.

Intego MAC Internet Security X9, the best Mac antivirus

Gone are the days when MAC had no virus issues, since MAC rose in popularity among the users, also rose the number of viruses and malware. The system itself has some great protection built it inside but for more security and better control of it, you will need a third-party dedicated solution.

Intego was made by Mac antivirus experts who have been building this kind of software last 25 years. The interface is easy to use and premade presets are really helpful, but the security suite can also be customized to fit your needs and desires.

intego screen

Since this is only available as a security suite, you are getting a firewall and some other security tools along with your antivirus that will run as a part of it.

The bad side is that scans can sometimes run slow, most of the time they are OK in terms of speed but occasionally they can switch to slower speeds and impact scanning time to some annoying times. Also, there is no webcam protection nor VPN service included where others on this list have them.

Bitdefender mobile security: best Android protection

While protection is not only needed for your gaming or workstation, software suites that are dealing with mobile and tablet security exist. The best of them is the Bitdefender antivirus mobile suite. Low on system resources and low on performance impact with the really great virus detection rate Bitdefender is at the top of suites for your phone.

bitdefender mobile

Consistent high virus detection packed with low battery impact is great but the suite comes with tons of other tools as well like browser security tools, email protection, and real-time link and notification protection.

The application will always scan each file and newly installed application in the background and alert and cut off any found threat. App itself is easy to install and use and most of the time it will do everything in the background for you but offer you customization if you need it.

The package also includes VPN and application lock that will let you protect the critical applications from being accessed as well as an online account scanner. Anti-theft and anti-loss tools, which allow you to find, remotely lock or wipe a stolen or lost device, add yet another layer of protection.

One thing that is missing from this great package is fraudulent call protection. Newer Android phones have this feature inside but it would be nice if Bitdefender had it as well.

Bitdefender, the best antivirus software

Now that we have covered specific cases of each platform, there is one player that has all of them covered and with a quality product, that player is BitDefender and it is great. Personally, this is my protection suite of choice and as I type this it is running in the background.

Bitdefender has it all, low system impact, as a matter of fact, it is one, if not, the lowest performance impact engine on the market currently and that is packed with a great and highly consistent virus & malware detection suite. Along with real-time malware protection, browser security, and anti-spam tools, you also get anti-phishing defenses, ransomware protection, and a strong firewall.

bitdefender screen

Bitdefender scores are very high in both the zero-day threat and real-world protection tests at AV-Test, an established organization that tests antivirus software. Despite being tested against tens of thousands of well-known and widespread malware threats, the software consistently achieves a 100% blocking rate.

The suite also comes with a restricted free VPN and with parental controls as well. Webcam and microphone protection are also included in the suite and on top of all, it has great pricing plans and constant discounts.

BitDefender is really a great package and it might sound too good, but after years and years of personally using it I have not had single malware or virus issue, the only thing that I would put as a negative is that system is severely slowed down when system scans are performed so be sure to run or schedule them when you are not using your computer. This, of course, can put some people off and I will admit it is a serious drawback but for me, the security of my workstation is more important than leaving the computer for 20 or so minutes in order to perform a full scan of the system.

How to Fix Unknown Hard Error in Windows 10
The “Unknown Hard” error that keeps on appearing in Windows 10 can put users in an unpleasant situation. This kind of error leads to the freezing of the taskbar, blackening of the screen, and sudden disappearance of the icons on the Desktop. And each time you try to open Windows, the system will only give you an error message saying that it’s a critical error and some applications like Start and Cortana won’t work. Upon analysis, it seems that the “sihost.exe” is not responding and that it is the one that’s causing the c000021a Unknown Hard error to pop up. Sihost.exe files represent the Shell Infrastructure Host which is an essential component in the Windows operating system. The Windows Shell Infrastructure Host is primarily responsible for handling some graphical elements of the operating system interface such as the Start menu and the taskbar transparency. And so if the Shell Infrastructure or Sihost.exe has stopped, has been removed, or corrupted, you will most likely have issues with the overall functionality of the Windows operating system and you’ll get the Unknown Hard error In addition, the ctfmom.exe Unknown Hard error may also occur due to incompatible drivers installed on your PC. Ctfmom is a process that identifies inputs such as handwriting, languages, and many more. It’s the one that controls the functions of background behavior. To resolve this issue, you need to first try to identify which application is the one that’s running the sihost.exe file. And if needed, you need to either update or reinstall or completely uninstall the problematic application.

Option 1 – Try to run the System File Checker

The SFC Scan or System File Checker, us a built-in utility in Microsoft Windows that can be found in the C:\Windows\System32 folder. This tool allows users to scan and restore any corrupted system files in Windows that might be causing the Unknown Hard error to appear. Before you use this tool, make sure to find out whether the sihost.exe on your computer is a Trojan that you have to remove or if it’s a file that belongs to a trusted Windows application. Once you have that sorted out, follow the steps below.
  • Tap Win + R to launch Run.
  • Type in cmd in the field and tap Enter.
  • After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
  1. Windows Resource Protection did not find any integrity violations.
  2. Windows Resource Protection found corrupt files and successfully repaired them.
  3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 2 – Try to use System Restore

You can also try using System Restore. This is one of the ways you can use it to back up your PC. Since restore points are created automatically each week by System Restore, you can use System Restore to restore your computer back to an earlier good point in time.

Option 3 – Try to troubleshoot the error in a Clean Boot State

Putting your PC in a Clean Boot state can help you diagnose and troubleshoot the issues in your system. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the Unknown Hard Error.
  • Log onto your PC as an administrator.
  • Type in MSConfig in the Start Search to open the System Configuration utility.
  • From there, go to the General tab and click “Selective startup”.
  • Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
  • Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
  • Click Disable all.
  • Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:
  • From the “Start” menu, go to System Configuration.
  • After that, switch to the General tab and click the option for “Normal Startup”.
  • Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
  • Then find and click “Enable all” and if prompted, you have to confirm.
  • Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
  • Restart your PC when prompted.

REvil vanishes over night without trace
REvilREevil is one of the most active and successful hacking groups connected to Russia and operating all over the world. The group recently demanded a huge bitcoin ransom for an attack targeting IT firm Kaseya in the USA. Since Tuesday blog and payment site run by REvil group cannot be longer reached without any kind of explanation or why. The reason behind the disappearance is unknown but has sparked speculation that the group may have been targeted deliberately by authorities. US President Joe Biden said he raised the issue with Vladimir Putin during a phone call on Friday, after discussing the subject during a summit with the Russian president in Geneva last month. Mr. Biden told reporters that he had "made it very clear to him...we expect them to act" on information and also hinted the US could take direct digital retaliation on servers used for intrusions. The timing of Tuesday's outage has sparked speculation that either the US or Russian officials may have taken action against REvil - though officials have so far declined to comment and cyber experts say sudden disappearances of groups are not necessarily uncommon. The development comes after a series of high-profile ransomware attacks which have hit major US businesses this year. The FBI accused REvil - also known as Sodinokibi - of being behind a ransomware attack on the world's largest meat processing company JBS last month.

Fix Windows Activation Error Code 0x8007007B in Windows 10
If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

  • Tap the Win + R keys to open the Run dialog box.
  • Type “cmd” and hit Enter to open an elevated Command Prompt.
  • After that type the vbs /dlv command and hit Enter to execute it.
  • Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.
  • In the Start Search box, type in “Slui 4” and tap Enter.
  • Next, select your country and click on Next.
  • Keep the window open and call the toll-free number of the country you’re from.
  • Afterward, a confirmation ID should be given by the automated system which you must take a note of.
  • Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.

Regular vs Gaming mouse comparison

You have probably heard a lot of good things about gaming mice, how they are better feeling, better in any way possible and it is all true, everything you heard is actually true, they are superior in any way to a regular mouse but with one big disadvantage, and that would be the price. While you can find a regular mouse for pocket change, a gaming mouse is in comparison very expensive even for entry-level ones.

gaming mouse

In this article we will explore all advantages and compare it with the regular one so you can come up with your own conclusion about do you really need one for yourself or if you are fine with regular.

Price

As stated price is one factor that does not favor gaming mice. Regular mouse for a personal computer goes around 10 or 20 USD, while entry-level in gaming one will be 40 USD and can go up to 250 USD, this large gap in price is usually determining factor why people pick up regular one. If you are on a really tight budget go for the regular one, but if you can afford a gaming one get it without second thoughts.

Software

This is where you will see the big difference between mice. Regular ones when connected are recognized and the driver is automatically installed and you can use it, same goes with gaming ones but with one big difference, you have an option to install additional manufacturers' software specially tailored for your mouse. In the application, you will be able to access some features that are specific to the mouse model that you could not set in typical Windows mouse properties. Beside more options software can also have features like setting your profiles and saving them to be recalled when you need them on the fly.

Sensitivity of mouse

The sensitivity of the mouse is measured in dots per one inch or short DPI, this is directly shown on your screen by how fast your mouse can move, higher sensitivity means your mouse will move faster across the screen and lower means it will move slower. All gaming mice come with buttons and settings that will allow you to change DPI on the fly and you can choose precise DPI settings in the software.

The regular mouse comes with DPI around 800 and goes to 1200 typically and does not have usually the option to change this while gaming mice start at 400 and can go as high as 26000 with the option to change it. Some regular mice can have only 1 option of DPI, usually very cheap ones.

Polling rates in mice

Pooling rate is the measurement of how often your mouse reports where it is positioned on the computer. The higher the pooling rate, the more responsive your mouse will be and vice versa. It is measured in hertz (Hz) and regular mice have them around 125Hz that is enough if you are using a computer for office, internet, and mail work.

If you are working in design or gaming you will need more than 125Hz polling rate, luckily gaming mice come with a minimum of 500Hz as an entry point and some hi-end models are going as far as 8000Hz. This very high pooling rate will get some extra load on your CPU but the mouse itself will be maximally responsive and will respond even to the smallest moves.

Ergonomics

Regular mice are well just mice, they are typical shape and size, gaming mice are made with ergonomics in mind. How they are made for extensive daily use of several hours per day they are constructed in a way to offer a pleasant and pain-free experience.

If you work on a computer for long periods of time consider gaming an ergonomic mouse since it will take the strain from hands and place them in a more natural position.

Macro keys

Gaming mice most of the time come with more keys compared with regular ones and good thing is that via its software you can tie certain actions to these extra keys making work or gaming more pleasant and quicker.

Components and material quality

In order to make regular mice more affordable and cheaper materials and quality of components had to suffer. Gaming mice have millions of guaranteed clicks by companies that make them before they break and regular ones usually do not guarantee a single one. This is due of course quality of materials that have been used in constructing these devices.

In the long term, if you use a gaming mouse for typical daily tasks it will outlive your regular one and on the side offer you more pleasant and responsive use along the way.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED CMUSBDAC.sys
If you encounter a Blue Screen error that points out to the CMUDA.sys, read on as this post will guide you in fixing it. The CMUDA.sys file is a Windows operating system driver file that is related to the USB Device Audio capabilities of a computer. There are times when this file causes Blue Screen error due to some conflicts in RAM or some incompatible firmware or hard disk issues, corrupted drivers or malware infection, and so on. There are various Blue Screen errors that are related to the CMUDA.sys file such as:
  • KMODE EXCEPTION NOT HANDLED
  • PAGE FAULT IN A NONPAGED AREA
  • IRQL NOT LESS OR EQUAL
  • SYSTEM THREAD EXCEPTION NOT HANDLED (CMUSBDAC.sys)
In most cases, the CMUDA.sys file usually triggers the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED Blue Screen error. Although this Blue Screen error may seem complicated, its workarounds are straightforward so you won’t have any problems in following them.

Option 1 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
  • Open the Devices Manager from the Win X Menu.
  • After opening the Device Manager, locate the device drivers that are marked with a small yellow exclamation mark icon and right-click on each one to open their Properties. On the other hand, you can also look for sub-entries under Sound, video, and game controllers like the C-Media USB Audio Class
  • After that, switch to the Driver tab and click on the Uninstall Device button.
  • Follow the screen option to completely uninstall it.
  • Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer. You can download the as C-Media USB Audio Class driver from the cmedia.com website.

Option 2 – Try to recreate the CMUDA.sys file

The first thing you can try is to recreate the CMUDA.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. Which is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.
  • Boot your Windows 10 PC in Safe Mode.
  • Then open File Explorer and navigate to this location: C:/Windows/System32/drivers
  • From there, look for the file named sys and rename it to CMUDA.old.
Note: As you can see, the file’s extension has changed from .sys to .old.
  • Now restart your computer and check if the CMUDA.sys Blue Screen error is now fixed.

Option 3 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:
  • Tap the Win + I keys to open the Settings panel.
  • Then go to Update & Security > Troubleshoot.
  • After that, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.
On the other hand, you can also try running the online Windows 10 Blue Screen troubleshooter from Microsoft. It is a wizard that could help you fix any Stop errors related to the CMUDA.sys file and will offer you helpful links as you use it.

Option 4 – Try running the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
  • Open the Command Prompt with admin privileges.
  • Then type in the following commands and make sure to hit Enter right after you type each one of them:
    • Dism /Online /Cleanup-Image /CheckHealth
    • Dism /Online /Cleanup-Image /ScanHealth
    • exe /Online /Cleanup-image /Restorehealth
  • Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 5 – Run System Restore

Running System Restore might also help in fixing Blue Screen errors related to the CMUDA.sys file.
  • Tap the Win + R keys to open the Run dialog box.
  • After that, type in “sysdm.cpl” in the field and tap Enter.
  • Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
  • After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

In this article we’ll take you through the basics of what a VPN does and some of the biggest benefits you can reap from buying one.

VPN: definition and how it works

VPN stands for Virtual Private Network, so its name already says a lot about what it does. 

A VPN is specialized software that keeps your browsing private and secure. Essentially it hides your identity, preventing possible cyberattacks and data theft. This is especially important in cases of public network use, where you’re highly exposed to potential threats.

To be more specific, this software encrypts your Internet Protocol (IP) address by filtering it through a server hosted by the VPN provider first. That way, it prevents your Internet service provider, third parties and lurking online thieves from tracking the actual you.

Some providers, such as Surfshark VPN with its IP Rotator feature, even make it a habit to frequently change your IP address to further protect your identity. With most VPN providers, you can also appear to be in a completely different country, adding to your disguise.

There are tons of advantages you can look forward to if you decide to use a VPN. Take a look at some of the crucial ones.

Benefits of using a VPN

When choosing a VPN, you can find both free and paid options. We recommend you go with the paid ones, since they have stronger security, encryption and data protection, as well as more advanced features. Free VPNs come with limitations and risk of malicious attacks on the software itself.

You can choose to buy a singular VPN service or opt for antivirus software that has a VPN built in, for example Bitdefender’s Ultimate Security plan. That depends on what you use your computer for and how much. 

When you pick one, here’s what it can do for you.

1. Access region-specific content

When we said you could change your location, we meant it. Say you’re using a streaming service and a show you desperately want to watch isn’t available in your country. You can use your VPN to make it look like you’re browsing from a country where it’s unlocked.

This option is also convenient for gamers who want to access maps, skins and other in-game items unavailable in their location.

In addition, you can use this powerful feature when you’re traveling to a region where some of your favorite content may not be accessible.

Do keep in mind that you need to read the Terms and Conditions (yeah, we know - who does that?) of your games and services before doing this, since you could end up getting a penalty. It’s also important to remember that there are entire countries that have strict regulations or even bans on VPNs, for example Belarus, Russia and China. So make sure to be very cautious with your VPN use, friends.

2. Browse like no one’s watching

VPNs shield your browsing habits from prying eyes on the web. Those can be malicious hackers or just third-party cookies tracking your every move to later bombard you with targeted ads. For example, Surfshark VPN features a Cookie blocker that blocks all cookie-related pop-ups and lets you browse in peace (and secret). It works even when the VPN is turned off, which is also pretty neat.

In addition, their CleanWeb 2.0 technology makes sure ads and especially malware don’t stand a chance at all, since they’re blocked before they can even load.

The inability of sites to track your browsing means they can’t collect and analyze any of your data. So, your personal information - or your company’s information in case that’s what you’re using your computer for - is entirely hidden and secure.

3. Save money

It’s well-known that the prices of certain items and services vary based on your location, browsing time, age and many other factors. This most commonly goes for airline tickets and hotel stays.

You can use your VPN to avoid high prices and surcharges. Clear all cookies, turn on your VPN and visit an online shopping site to check out their prices. Then compare your findings with the offers you see when your VPN is off, when you spend a long time on the site or have an active account with the company. 

Sometimes this can really help you find the best deals and avoid breaking the bank. But again, check the Terms and Conditions before you purchase something using a VPN.

4. Secure your smart home

The more smart devices you have connected to your network, the more exposed you are to potential cyberattacks. Phones and computers are generally designed to be decently secure even without a VPN or antivirus, but smart home devices leave a lot to be desired in that regard. 

Protecting your home network with a VPN software means all devices connected to it are secure, be it an air purifier or Alexa.

5. Prevent connection slowdown

Your ISP can intentionally slow down your internet speed based on how much data you’ve consumed (data throttling) or your activities online (bandwidth throttling).

But with a VPN, what kind of data you send and receive and how much is entirely hidden. Therefore, if your ISP can’t see you, they can’t control you and they can’t throttle down your speed.   

The bottom line

You can never be too safe online. So definitely think about getting yourself a solid VPN to pump up your privacy and security as much as you can. And if you have any questions or need help choosing the perfect software for you, feel free to reach out to us.
