Error Causes
Researchers have discovered 16 vulnerabilities in Bluetooth connections that could be exploited and make from minor to some serious damage to your device. The flaw can be used on chips manufactured by Intel, Qualcomm, and Texas Instruments while connecting to external devices like speakers, headphones, keyboards, mice, etc.
Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!
There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.
To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.
This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.
If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.
Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.
In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.
If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now.
Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).
A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice.
For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.
Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.
This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.
As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.
To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.
Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.
In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.
Bloatware is one of the biggest culprits of slow computer speed.
Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.
To boost your Windows 11 computer, go to Settings > Apps > Installed apps. You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’.
Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.
These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!
Afraid of the growing threats online? As you should be. But we’re here to show you what kinds of malware are out there and what you can do to keep them at bay.
Malware comes from the term malicious software. It’s software designed to attack and exploit devices and networks to the advantage of the hacker who made it.
Malware can be transmitted in different ways. Most commonly this happens via infected USB drives, downloadable files or malicious websites. Depending on the type and ultimate goal, the consequences of a malware attack can range from negligible to catastrophic.
A virus is typically spread via infected files, websites or links. It’s one of the oldest malware types and one of the most difficult to get rid of. That’s because, once activated, it replicates itself - hence the name.
It can perform different kinds of attacks, depending on what the creator wants to achieve. The main characteristic of a virus is that it really doesn’t show itself until you activate the host. So that’s a scary thought for sure.
Sometimes an ad blocker isn’t enough to fight off unwanted ads. And some of them can, unfortunately, be malicious. They may redirect you to infected sites or prompt downloads of risky files. Even just opening a malicious site can lead to data theft.
So, definitely be careful when clicking around. Even if an ad seems completely legitimate, you can never be too sure.
Through ransomware, cybercriminals gain access to a user’s data and use it to extort them for money. Basically, the user is threatened with data deletion or even exposure if a ransom isn’t paid by a specific deadline.
This is a particularly nerve-wracking type of malware. If it targets an individual, it preys upon their sense of anxiety, fear, guilt and even shame. If it targets a business (which is a lot more common), it preys upon not only that business’s profit but also every single one of their customers and their data.
This type of malware disguises itself very well as a legitimate-looking program. Once you download it, hackers can get full access and control of your device, data and network. They can even be hidden in games, apps and attachments. They cannot self-replicate, though, so we guess that’s… good news?
Worms can replicate, just like viruses, but you don’t need to actually activate the infected program for them to get going. They can be used for various purposes, ranging from data deletion to file encryption to support a ransomware attack.
Spyware refers to malicious software that stays hidden on your computer and monitors your activity. The best-known type is keyloggers. This can be used to steal sensitive data like passwords and banking information.
Rootkits are among the most dangerous types of malware. They allow administrative access and full control of a device, which lets hackers continue hijacking all your data and monitoring your activity without your knowledge.
Botnets are networks made up of bots - computers that cybercriminals have infected with malicious software. Bots and botnets give hackers remote access to users’ devices and allow them to spy on your camera, take screenshots, memorize passwords and launch Distributed Denial of Service attacks. This one truly makes your hair stand on end.
You know the old adage - better safe than sorry. And trust us, malware attacks are such a pain in the you-know-what that you really don’t want to be sorry.
Luckily, there are simple solutions that can shield you from most digital threats these days. What you want to be looking at is a solid antivirus program. Well, technically, you need an antimalware program, but since the latter evolved from the former, we still mostly refer to them as antivirus software.
The majority of antimalware programs these days don’t just shield you from potential risks online, but include additional features as well. For example, some Bitdefender antivirus packages also include parental control and a VPN. And Bitdefender is not just for PCs either - it offers protection for your beloved iPhone or Android as well. You can throw in a password manager in there too, for an additional layer of security.
If you aren’t too concerned about all these various threats or feel like you don’t need extra security, you can at least take a step to protect your information from being exposed to lurking cybercriminals as you’re browsing. This can be done through a good VPN like Surfshark, which hides your identity in the digital space and prevents your data from being tracked.
Choosing the right protective software is especially important if you have children with access to the Internet, since they’re unfortunately even more vulnerable to malicious attacks. If you aren’t sure what the right kind of antimalware program is right for you, you can reach out to us and we’ll be happy to help keep your entire household or office digitally secure.
The truth is that there’s no way to be 100% protected in the online world. Hackers are constantly coming up with new ways to infiltrate our devices. But malware-battling software evolves along with them and there’s still plenty you can do to keep risks away. Stay safe!
