Online viruses infect your computer or smartphone by making copies of themselves and attaching them to files in your devices. They can damage your computer by reformatting the hard drive or deleting files. Online viruses can also slow down your device, flood storage, and increase network activity, making it hard to access the internet. Here are five common online viruses and how to avoid them.

Browser Hijacker

A browser hijacker is a virus that changes your browser settings, causing various threats like altering your default home page. It usually redirects your browser to other potentially harmful websites without your permission. Browser hijacking can attack your computer by introducing adware, identity theft, or web tracking. Adware infects your computer and fills your browser with ads that slow down your computer. The ads are usually annoying and difficult to control.

Identity theft allows a hacker to collect your personal information and steal your identity. A hacker can also track your location after hijacking your computer. They can monitor all your online activities and record everything you do. Hackers can get all kinds of information, including IP address, search history, and page views.

When your computer is hijacked, you may realize you are low on space and get constant pop-up ads. You can protect your computer from being hijacked by avoiding untrustworthy websites. Additionally, you can avoid suspicious links and downloads as they may contain viruses. Ensure that you use a secure browser that blocks malicious extensions. When you keep your system updated, you can identify and fix any loopholes that hijackers exploit.

Web Scripting Virus

Resident Virus

A resident virus can hide in your RAM and infest files running in your computer. It can even attach to an antivirus program and infects files running through it. The virus does not need to be executed as it executes after loading the operating system. It can either work quickly, causing massive damage, or slowly and spread widely while remaining undetected.

Direct Action

A direct action virus infects executable files in your computer. It then replicates and infects other files making them inaccessible. The virus only spreads when you execute the file. Luckily this virus is easily detectable and removable using an antivirus application. You can prevent this type of virus by scanning for viruses before installing programs or downloading email attachments.
