What are the most common computer viruses?
Assuming you would like an article discussing the most common computer viruses:
A computer virus is a type of malware that inserts itself into your system, affecting how your computer runs without you realizing it. There are lots of different types of computer viruses, but some are more common than others. Here are the five most common viruses and how to protect yourself from them.
1. The Bundler Virus
The Bundler virus is also known as PUA.A or Adware. It’s one of the most common viruses because it’s easy to contract and hard to get rid of. All you need to do is download a free program that has the Bundler virus bundled with it. Once it’s on your computer, it will start showing you ads, even if you’re not browsing the internet. The ads will be for things you’ve recently looked at online, which can be very annoying.
To protect yourself from the Bundler virus, only download programs from websites you trust. If you’re not sure if a website is trustworthy, do a quick Google search to see if anyone has reported the site for bundling viruses with their programs.
2. The Cryptolocker Virus
The Cryptolocker virus is a type of ransomware. It will encrypt your files so you can’t open them unless you pay a ransom. This virus is spread through email attachments. You might get an email that looks like it’s from a company or organization you do business with. The email will have an attachment, and if you open the attachment, the virus will start encrypting your files.
To protect yourself from the Cryptolocker virus, don’t open attachments from people you don’t know. If you get an attachment from someone you know, but it seems out of character for them, contact them to make sure they actually sent it before you open it.
3. The Zeus Virus
The Zeus virus is a type of malware that steals your information. It’s usually spread through phishing emails. These are emails that look like they’re from a legitimate company, but they’re not. They’ll try to get you to click on a link or attachment so the virus can install itself on your computer. Once it’s installed, it will start collecting your personal information, like your bank account login information.
To protect yourself from the Zeus virus, don’t click on links or attachments in emails unless you’re absolutely sure they’re from a legitimate source. If you’re not sure, go to the website yourself and log in rather than clicking on a link in an email.
4. The WannaCry Virus
The WannaCry virus is a type of ransomware that encrypts your files and asks for a ransom to decrypt them. It was first released in 2017 and it was spread through a vulnerability in the Windows operating system. Once it infected a computer, it would spread to any other computers on the same network. This virus caused a lot of damage because it infected so many computers.
To protect yourself from the WannaCry virus, make sure your computer’s operating system is up to date. Microsoft released a patch for the vulnerability that the WannaCry virus exploited, so if you have the latest updates, you should be safe.
5. The NotPetya Virus
The NotPetya virus is another type of ransomware. It first appeared in 2017 and it spread in a similar way to the WannaCry virus. It exploited a vulnerability in the Windows operating system and it spread to other computers on the same network. This virus was used in a cyberattack against a Ukrainian company. The attackers encrypted the company’s files and then demanded a ransom to decrypt them.
To protect yourself from the NotPetya virus, make sure your computer’s operating system is up to date. Microsoft released a patch for the vulnerability that the NotPetya virus exploited, so if you have the latest updates, you should be safe.
These are the five most common computer viruses. To protect yourself from them, only download programs from trustworthy websites, don’t open attachments from people you don’t know, and make sure your computer’s operating system is up to date.
