Outlook PST Errors

Problems occur when your PST file becomes corrupted or hits the size limit. Outlook will start to display error messages. These errors include like 0x80040119, 0x80040600, and 0x8004060c.

Error Causes

You might think Outlook problems are just a minor inconvenience. You can’t access your emails and contact information, but that doesn’t actually affect computer security, right? Wrong! Outlook problems can indicate serious corruption issues within your system.

In many cases, your PST file can even be targeted specifically by a virus.

Today, many viruses are specially designed to steal personal information and then sell that information on the online black market. Since so much personal data is stored within Outlook’s PST file, this is often the first place that viruses look.

If you don’t want some hacker in a foreign country to read your emails, steal your contact information, or do all sorts of other dangerous tasks, then we advise you to fix your PST problem as soon as possible.

Other causes include hitting the 2GB memory limit on older versions of Outlook, erroneous SMTP settings, etc,.

Further Information and Manual Repair

PST errors are an incredibly annoying problem. However, thanks to powerful software like Stellar Phoenix Outlook PST Repair, it has never been easier to fix Outlook and recover all of the data inside your PST file. That means that you won’t lose contact information, calendar entries, emails, or any other information stored in Outlook.

ScanPST.exe rarely fixes problems with the PST file. Since the application is only a few megabytes in size, its effectiveness is very limited. Although Microsoft designed ScanPST.exe to be an effective solution to any PST files, it fails miserably.

Better Alternatives to Microsoft's ScanPST.Exe

Ultimately, after downloading ScanPST.exe and running it, your Microsoft Outlook will still be unable to send or receive emails. And, to make matters worse, you might also be unable to access contact data or read your old emails.

Unlike other PST repair solutions, ScanPST.exe will not recover deleted emails or other lost Outlook data. In fact, using ScanPST.exe can sometimes cause your personal data to become even more difficult to recover.

If you do want to try out ScanPST.exe, then go ahead. While it probably won’t make your PST errors worse, it won’t even come close to fixing them. If you’re ready for a more serious solution to PST problems, then keep reading.

Microsoft has started to use group along with every open window in the Taskbar ever since the release of Windows 10. Early on, they used to show an individual entry for each one of the windows after grouping them which makes the taskbar look cleaner and organized. However, the main issue lies in the fact that you have to hover on your desired window to get on to them. At the time of writing, you need to tap the Ctrl key and click on the taskbar icon to open the last active window but you have to only click on the program’s taskbar icon after you apply the tweak given in this post for the last active window to open. Take note that the “Last Active” windows feature will only work if the taskbar buttons are combined. Before you get started doing the instructions given below, you need to create a System Restore Point first since you will be dealing with registry files and modifying some of the critical settings in Windows 10. Once you’ve done this, proceed to the given steps below. Step 1: Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor. Step 2: If a User Account Control or UAC prompt appears, just click on Yes to proceed to open the Registry Editor. Step 3: Next, navigate to the following registry path:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced

Step 4: From there, right-click on the right side of the panel and select New > DWORD (32-bit) and then name it “LastActiveClick”. Step 5: After that, double click on the newly created DWORd to modify its value. Put “1” as its value data. Step 6: Then click OK and close the Registry Editor. Step 7: Now restart your computer to successfully apply the changes made. Note: In case you want to revert back to the default configuration, all you have to do is set the value data of LastActiveClick to “0” or simply delete that DWORD and restart your computer to successfully apply the changes made.

Hello and welcome to our Business Email Etiquette. Most people have experience in writing emails at some point before in their lives. However, the emails an average person writes are probably personal emails and not mails for work purposes. Emails you send to friends are incredibly different in content and context to business emails you would send to customers or employers or even other colleagues in your workforce. So, if you have a job that involves you writing emails to people in business style, learning business email etiquette is an absolute must for you.

 1. Heading layouts

When you are sending emails to friends, you generally lay them out like a memo. This means there is very little detail in the layout besides basic greetings and paragraphs, usually starting with the greetings. However, with a business email, it is best to lay it out exactly like you would lay out a formal letter. You need to put the company’s address in the right-hand corner and the date as well. Only then must you go on to the greetings. This will make your email look more formal, making you seem like a professional who knows what they are doing as opposed to someone who just couldn’t be bothered spending the extra time to get the layout right.

 2. Proper greetings

 When you are sending an email to a friend, you usually greet them informally. If their name was Mary Johnson, you’d probably start your letter with a ‘Hey Mary’ or a ‘Hello Mary.’ However, this is not considered a professional way to write an email to a customer or other important person in your business. Again, you must use the proper method that you would greet someone with were you writing them a formal letter instead. If your customer is Mary Johnson again, you should greet her with respect. ‘Dear Ms. Johnson’ would be the most appropriate way to start off your letter’s actual body in this case. If you do not know the recipient’s name, then you should start with a simple ‘Dear Sir or Madam.’ Politeness will always get you incredibly far, no matter what line of work you are in.

 3. Informal language

 You should get straight to the point with your email. Don’t dawdle on with it like you would if chatting to a friend and don’t write it how you would speak either. You use language that sounds impressive and smart while not using such obscure language that your recipient doesn’t know what you are saying. All the time, you must keep it informal where possible, possibly even impersonal as well. It will make you seem very professional in the long run.

 4. Signing off

When you are sending your email, you must end it as you would with a letter also. Don’t just say ‘Bye’ and your first name; that is too personal. You need to say ‘yours sincerely if you know the name of the recipient and ‘yours faithfully’ if you do not. Then you should end with your full name and whatever position you have at the company. (CEO, technical staff etc.) So there you have it! All you need to do now is to show your boss that you can handle the emails from now on!

If you have encountered the “YOU ARE NOT AUTHORIZED TO ACCESS THIS WEB PAGE AS PER THE DOT COMPLIANCE” error while trying to visit a website using either Firefox or Chrome browser, then read on as this post will guide you on how you can fix this error. Apart from this error message, you might also see an alternative message that says, “Web Page Blocked! The page you have requested has been blocked because the URL is banned as per the Government Rules”. When you get any of the aforementioned error messages when visiting a website, this means that it has been marked. It is mostly recommended to not access the site as it might be blocked for some illegal reason. However, if you are certain that the website is legitimate and safe and you believe that it has been blocked by accident, then you can check out the given methods in this post to unblock and access the blocked or restricted website. There isn’t actually a straightforward way to remove the restriction on the website or the DOT compliance. And it won’t matter what browser you use as you will still get the same error. Thus, the best way to go about this issue is for you to bypass the ISP restriction. But before you proceed, keep in mind that the ISPs (Internet Service Providers) can block any website when a request goes through their servers.

Option 1 – Try changing the DNS

If the request to access the website does not go through the ISP’s DNS server, you might have a chance in accessing it by changing your DNS settings. You can try using the Google Public DNS.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try to install a Proxy Extension

You could also try installing a Proxy extension or Proxy software as it could also help you access the website you are trying to open as it allows you to access the blocked websites by routing the request through their server. Aside from that, it can also hide it from ISPs to make them look like the content is coming from the proxy servers.

Option 3 – Try using a VPN connection

There are instances when the network that your computer is logged on might have blocked your access to the website you are trying to open and so to fix it, you can try to use a VPN connection. There is a lot of free VPN software out there but just make sure that you install a trusted one. Once you’ve connected using VPN, try to open the website again and see if you can now access it.

Option 4 – Check the Windows Host file

You can also try to cross check the Windows Hosts file to find out if the website you are trying to open has been blocked because if it is, then it’s no wonder why you’re getting the ERR CONNECTION TIMED OUT error in Chrome. There are instances when some third party application modifies the file and add some websites to the block lists. So if the website is indeed blocked, you need to remove it from the list.

Option 5 – Try to contact your ISP

If none of the options given above worked, then you can try to contact your ISP as there are times when DOT clears a website, the ISPs are still blocking it. Thus, it’s probably better if you reach out to them and ask them to unblock the website from their end.

Error Code  0x80070490 - What is it?

Error code 0x80070490 occurs in versions of Windows including Windows 8 or 8.1 and Windows 7 or Windows Vista. This error often arises when users attempt to install updates via Windows Update or Microsoft Update.

The main reason for the error relates to the Component-Based Servicing (CBS) manifest which has become damaged. When the error occurs, the Windows device is unable to successfully install updates.

Solution

Error Causes

Error code 0x80070490 might appear for various reasons but is most prominent in the following cases:

• Attempts to install Windows 8 or 8.1
• A corrupted Component-Based Servicing (CBS)

Further Information and Manual Repair

The solutions for error code 0x80070490 vary so users may need to attempt each solution to find the best results.

1. Repair Corrupted Windows Files with System File Checker

The System File Checker (SFC.exe) is a Windows-based utility that enables users to check and repair corrupted or damaged system files. It can also restore missing systems files which can be the cause of errors such as error code 0x80070490.

To repair files, begin scan by swiping the right edge of the screen then opening the search box. Type Command Prompt, right-click this option, then select Run as Administrator. Once the scan begins, wait for the process to be completed then restart your device. Check if the error is resolved by reattempting updates. If error code 0x80070490 in Windows 8 or 8.1 persists on your device, proceed to the solution below.

2. Perform Clean Boot

A clean boot is one of the best ways to reduce conflict among files – an issue that may arise whenever users update, install or run programs on their Windows device.

To run a clean boot, your device reboots using limited drives and programs. The process allows you to identify which conflict among programs is causing errors on your Windows device.

You can access the clean boot tool by entering msconfig in the search box. Select Services, then System Configuration. Check the Hide all Microsoft services checkbox then select Disable all. Next, go to the Startup tab, click and open Task Manager. After selecting the Startup tab, make sure you right-click each startup program. Click Disable from the context menu then close Task Manager when done. Select OK on the System Configuration menu then restart your machine to clean boot Windows 8 or 8.1.

If the clean boot successfully identifies and resolves issues with corrupted files, you will be able to access updates using Windows Update or Microsoft Update. Error code 0x80070490 will no longer occur. But if that proves unsuccessful, other options are available below including running Windows Update Troubleshooter.

3. Run Windows Update Troubleshooter

This method can provide a simple solution for users as it verifies whether your Internet connection, network adapter and Windows Update services are functioning properly. However, if you are uncertain as to whether you will be able to troubleshoot, seek assistance from a qualified Microsoft technician.

To run Windows Update Troubleshooter, simply download from Microsoft’s website. Be sure you are downloading the tool recommended for your operating system, in this case Windows 8 or 8.1. After you download Windows Update Troubleshooter, run it to enable the tool to check for and resolve update issues on your device.

4. Use DSIM or System Update Readiness Tool

The System Readiness Tool or DSIM is another method you can use to correct issues related to error code 0x80070490. This tool checks problems on your system that might prevent your computer from performing Windows updates including issues related to damaged system files.

Once you download and install this tool, it will be able to run automatically. The process may be technical, however, requiring specialized knowledge to successfully download and run the tool. Consider getting assistance from an IT professional in this case. Also, check Microsoft's online resources to download the tool.

5. Use an Automated Tool

Having an automated tool at hand will enable users to always be prepared. Download a powerful automated utility tool to provide solutions whenever error codes or other problems affect your Windows 8 device.

Computers viruses, worms, ransomware, etc. are kinds of malicious software that no user should take lightly. On several occasions, we have touched upon security steps that each user should take in order to protect its identity and data. Sadly sometimes even when all precautions are taken some malware can still slip through and wreak havoc. Today we are looking at some of the worst or the best, depending on your view that has indeed wreaked plenty of havoc.

10 worst computer viruses in history

In the list of the 10 most famous computer viruses below, we show the costs, dates, reach, and other key facts. First a note about terms: we use the words “virus” and “worm” interchangeably because most readers search for them that way. But there’s a subtle difference that we explain after the list.

1. Mydoom – $38 billion

The worst computer virus outbreak in history, Mydoom caused estimated damage of $38 billion in 2004, but its inflation-adjusted cost is actually $52.2 billion. Also known as Novarg, this malware is technically a “worm,” spread by mass emailing. At one point, the Mydoom virus was responsible for 25% of all emails sent. Mydoom scraped addresses from infected machines, then sent copies of itself to those addresses. It also roped those infected machines into a web of computers called a botnet that performed distributed denial of service (DDoS) attacks. These attacks were intended to shut down a target website or server. Mydoom is still around today, generating 1% of all phishing emails. That’s no small feat considering the 3.4 billion phishing emails sent each day. By that figure, Mydoom has taken on a life of its own, infecting enough poorly-protected machines to send 1.2 billion copies of itself per year, 16 years after its creation. Though a $250,000 reward was offered, the developer of this dangerous computer worm was never caught. Wondering what makes the world’s most secure computers so safe? See the Tech@Work guide: Upgrade to the World's Most Secure and Manageable PC

2. Sobig – $30 billion

The 2003 Sobig computer virus is actually another worm. It is second only to the Mydoom virus in its scope. The $30 billion figure is a worldwide total, including Canada, the U.K., the U.S., mainland Europe, and Asia. Several versions of the worm were released in quick succession, named Sobig.A through Sobig.F, with Sobig.F being the most damaging. This cybercriminal program masqueraded as legitimate computer software attached to emails. It disrupted ticketing at Air Canada and interfered with countless other businesses. Despite its widespread damage, the creator of the successful bug was never caught.

3. Klez – $19.8 billion

Klez is a close third on the list of the worst computer viruses ever created. With nearly $20 billion in estimated damages, it infected about 7.2% of all computers in 2001, or 7 million PCs. The Klez worm sent fake emails, spoofed recognized senders and, among other things, attempted to deactivate other viruses. As with other viruses and worms, Klez was released in several variants. It infected files, copied itself, and spread throughout each victim’s network. It hung around for years, with each version more destructive than the last. Windows has come a long way since most of the computer viruses on this list hit the web. Thankfully, built-in protection with Microsoft Defender is always on the watch.

4. ILOVEYOU – $15 billion

The year 2000’s ILOVEYOU virus worked by sending a bogus “love letter” that looked like a harmless text file. Like Mydoom, this attacker sent copies of itself to every email address in the infected machine’s contact list. Shortly after its May 4 release, it had spread to more than 10 million PCs. The virus was created by a college student in the Philippines named Onel de Guzman. Lacking funds, he wrote the virus to steal passwords so he could log into online services he wanted to use for free. He reportedly had no idea how far his creation would spread. This virus is also known as Loveletter. Need to up your remote work security game before there’s another entry on the list of most deadly computer viruses? See our guide: How to Work Remotely and Securely

5. WannaCry – $4 billion

The 2017 WannaCry computer virus is ransomware, a virus that takes over your computer (or cloud files) and holds them hostage. The WannaCry ransomware ripped through computers in 150 countries, causing massive productivity losses as businesses, hospitals, and government organizations that didn’t pay were forced to rebuild systems from scratch. The malware raged like wildfire through 200,000 computers worldwide. It stopped when a 22-year-old security researcher in the U.K. found a way to turn it off. Computers with out-of-date operating systems were hit especially hard. That’s why security experts always recommend updating your systems frequently.

Ransomware strikes again

In September 2020, one of the potentially largest computer virus attacks in medical history hit Universal Health Services. The U.S. hospital chain, which has more than 400 locations, was reportedly struck by damaging ransomware. The attack forced the cancellation of surgeries and made healthcare workers switch to paper records.

6. Zeus – $3 billion

The Zeus computer virus is an online theft tool that hit the web in 2007. A whitepaper by Unisys three years later estimated that it was behind 44% of all banking malware attacks. By then, it had breached 88% of all Fortune 500 companies, 2,500 organizations total, and 76,000 computers in 196 countries. The Zeus botnet was a group of programs that worked together to take over machines for a remote “bot master.” It originated in Eastern Europe and was used to transfer money to secret bank accounts. More than 100 members of the crime ring behind the virus, mostly in the U.S., were arrested in 2010. It’s not as prominent today, but some of the virus’ source code lives on in newer botnet viruses and worms. Zeus caused documented damage of $100 million. But the real cost in terms of lost productivity, removal, and undocumented theft is undoubtedly much higher. A $3 billion estimate, adjusted for inflation, puts this virus at a cost of $3.7 billion in today’s dollars.

7. Code Red – $2.4 billion

First observed in 2001, the Code Red computer virus was yet another worm that penetrated 975,000 hosts. It displayed the words “Hacked by Chinese!” across infected web pages, and it ran entirely in each machine’s memory. In most cases it left no trace in hard drives or other storage. Financial costs are pegged at $2.4 billion. The virus attacked websites of infected computers and delivered a distributed denial of service (DDoS) attack on the U.S. White House’s website, www.whitehouse.gov. In fact, the White House had to change its IP address to defend against Cod Red. Can your printer get a virus? See our cool infographic: The State of Printer Security

8. Slammer – $1.2 billion

The SQL Slammer worm cost an estimated $750 million across 200,000 computer users in 2003. This computer virus randomly selected IP addresses, exploiting vulnerabilities and sending itself on to other machines. It used these victim machines to launch a DDoS attack on several internet hosts, significantly slowing internet traffic. The Slammer worm hit banks in the U.S. and Canada especially hard, taking ATMs offline in many locations. Customers of Toronto’s Imperial Bank of Commerce found themselves unable to access funds. The attack reared its ugly head again in 2016, launching from IP addresses in Ukraine, China, and Mexico.

9. CryptoLocker – $665 million

Thankfully, ransomware attacks like the 2013 CryptoLocker virus have dipped since their 2017 peak. This malware attacked upwards of 250,000 machines by encrypting their files. It displayed a red ransom note informing users that “your important files encryption produced on this computer.” A payment window accompanied the note. The virus’ creators used a worm called the Gameover Zeus botnet to make and send copies of the CryptoLocker virus. According to a report by security firm Sophos, the average ransomware attack costs a business $133,000. If we estimate that CryptoLocker hit 5,000 companies, that would put its total cost at $665 million. Where will cybersecurity go next? See our guide: The Future of Cybersecurity

10. Sasser – $500 million

The Sasser worm was written by a 17-year-old German computer science student named Sven Jaschan. He was arrested at the age of 18 in 2004 after a $250,000 bounty was posted for the computer virus’ creator. A friend of Jaschan’s tipped authorities that the youth had penned not only the Sasser worm but also the damaging Netsky.AC attack. Jaschan was given a suspended sentence after it was found he was a minor when he wrote the malware. The Sasser worm crashed millions of PCs, and though some reports put damages at $18 billion, the relatively low infection rate suggests a more likely cost of $500 million. Other notable viruses The top 10 worst computer viruses above are just the ugly tip of a gargantuan digital iceberg. With a million new malware programs popping up every 3 years, we may miss the forest for a few outstanding trees. Here are just a few more viruses that have wreaked havoc over the years: Mimail: This worm tried to harvest data from infected machines to launch a string of DDoS attacks, but was relatively easy to remove. Yaha: Yet another worm with several variants, thought to be the result of a cyber-war between Pakistan and India. Swen: Written in C++, the Swen computer worm disguised itself to look like a 2003 OS update. Its financial cost has been pegged at $10.4 billion, but not reliably. Storm Worm: This worm showed up in 2007 and attacked millions of computers with an email about approaching bad weather. Tanatos/Bugbear: A 2002 keylogger virus that targeted financial institutions and spread to 150 countries. Sircam: A computer worm from 2001 that used counterfeit emails with the subject line, “I send you this file in order to have your advice.” Explorezip: This worm used fake emails to spread to every machine on thousands of local networks. Melissa: The most dangerous computer virus in 1999, Melissa sent copies of itself that looked like NSFW pics. The U.S. FBI estimated cleanup and repair costs at $80 million.

REevil 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.
