Browser hijackers (sometimes called hijackware) are a kind of malicious software that changes internet browser configurations without the user’s knowledge or permission. These types of hijacks appear to be increasing at an alarming rate around the world, and they could be actually nefarious and often harmful too. Browser hijackers could do more than just modifying homepages. The idea is to force users to visit specific websites that are looking to improve their website visitor traffic and produce higher ad earnings.

Many web browser hijackings come from add-on applications, i.e., toolbars, browser helper objects (BHO), or plug-ins added to browsers to provide them additional features. Browser hijackers sneak into your computer in addition to free software application downloads also that you unintentionally install alongside the original. Popular examples of browser hijackers include Conduit, CoolWebSearch, Coupon Server, OneWebSearch, RocketTab, Searchult.com, Snap.do, and Delta Search. Browser hijacking can result in severe privacy issues and also identity theft, affect your browsing experience by taking control of outgoing traffic, substantially slows down your personal computer by consuming a lot of resources, and cause system instability also.

How to fix a browser hijack

Certain browser hijacking could be quite easily stopped by discovering and eliminating the corresponding malware software through your control panel. However, most hijackers are hard to get rid of manually. No matter how much you attempt to remove it, it may come back again and again. Moreover, browser hijackers could modify the Windows registry therefore it can be very hard to repair manually, particularly when you’re not a very tech-savvy individual.

Internal Error 2753 - What is it?

Internal error 2753 is associated with Windows Installer failure. The Windows Installer is basically an in-built software program in Windows 7 and 8. It installs all programs on the system smoothly, saves the program in the computer program files and in the Windows Registry. Though this can be carried manually Windows Installer makes the installation process much easier. However, internal error 2753 can cause a great deal of distress and frustration during program installation. This error prevents you from installing your desired program successfully.

Solution

Error Causes

The 2 known causes for Internal Error 2753 are:

• Viral infection
• Windows Installer not properly registered

Further Information and Manual Repair

To resolve internal error 2753 on your system, try the methods discussed below. These methods are easy and require no technical expertise. Let’s get started:

Method 1 - Remove All Malicious Programs

Malicious programs like viruses, malware, adware, Trojan and spyware can corrupt programs on your PC like Windows Installer. If this is the underlying cause of error code 2753, then simply download a powerful antivirus on your system. Run it to scan for all such malicious programs and remove them. Once your PC is clean, try installing your desired program. This will hopefully resolve the issue. If the error still pops up then try method 2.

Method 2 - Register Windows Installer Properly

To do this, go to the start menu and then open Run and type ‘cmd’ in the box, and press OK. This will open the DOS command window. In the command prompt type "regsvr32 vbscript.dll" and then press Enter to proceed. After that, you will see a message that will read as "DllRegisterServer in vbscript.dll succeeded." This means Window Installer files have been successfully registered on your PC.  Now you can try installing your desired program again. If the installation begins and completes successfully, then the error is resolved.

Method 3 - Undo Recent Changes

If nothing works, then use the Windows System Restore Utility tool to undo recent changes. This will bring back your PC in the former state before you experienced the error 2753 on your PC. To access System Restore Utility, press Start and type System Restore in the search box. Now follow the steps in the Wizard to choose a restore point. Once you select the point, reboot your system to activate changes.

PrintNightmare vulnerability has been a struggling issue for Microsoft in the past weeks, each time it seems to be addressed and fixed something new popped up and it still had issues. Microsoft finally addressed the issue but with a price. The default behavior of Point and Print is changed. From this fix onward, the Point and Print driver installation and update behavior will require administrator privileges, which should prevent the exploit to the Windows Print Spooler that could be used by malicious individuals to gain administrative privileges in Windows. The drawback of this fix from Microsoft is that non-elevated users may have difficulty adding or updating printers. Microsoft feels that the security risks caused by PrintNightmare are worth the tradeoff, though. If you really want to let non-elevated users add printers, you can follow the instructions in this Microsoft Support article to disable this mitigation with a registry key. However, doing so will expose you to this known vulnerability and isn’t recommend.

If you are not able to access the Windows 10 Advanced troubleshooting options within Windows then you’ve come to the right place as this post will guide you on how you can repair or boot the Windows 10 installation without losing data using the bootable installation USB or DVD media.

A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”

This issue might be caused by two possible reasons such as:

1. VPN issues
2. Not enough space on the System Reserved partition

To resolve the problem, here are some tips that might help:

Option 1 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 2 – Try to free up space in the System Reserved partition

The System Reserved partition is a part of the hard disk created when Windows is first installed on it. It is where the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and the reserves space for the startup files are stored. And as mentioned early on, the error might be due to some insufficient space in the System Reserved partition so the next thing you can do is to increase the space in this partition. Note that it is a complex process so you need to make sure that you have made backups to all your data on the computer. So if ever something goes out of hand, at least you have copies of your important files in case you aren’t able to boot into the system at all.

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?

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. Flashback: A Mac-only virus, Flashback infected over 600,000 Macs in 2012 and even infected Apple’s home base in Cupertino, Calif. In 2020, there’s now more malware on Macs than on PCs. Conficker: This 2009 virus still infects many legacy systems and could do significant damage if it ever activates. Stuxnet: This worm is reported to have destroyed Iranian nuclear centrifuges by sending damaging instructions.
