Most users know when their computer is performing poorly but we are not always sure if this problem is being caused by a computer virus. Computer viruses are a type of malware that comprises malicious computer codes designed to damage devices and potentially steal their information. Created to replicate again and again, computer viruses change the way your computer works and compromise its memory, programs, and information files.
A computer can catch a virus in numerous ways, most of which involve exposure to the Internet. Visiting an infected website and downloading free content – such as games, toolbars, and media players – can expose your computer to viruses. Your device can also pick up a virus if you open an infected email and/or email attachments. When you share music, photos, and other content, you are potentially exposing your computer to viruses. Even downloading infected software is also a potential source of viruses.
To know whether your computer has been affected by a virus, ask yourself these important questions:
- Is my computer working slowly?
- Have I lost data for no obvious reason?
- Does my computer sometimes stop functioning for no apparent reason?
- Is my computer crashing repeatedly?
If you answer “yes” to even one of the questions above, chances are good that your computer has been affected by some sort of computer virus and you will want to have it looked at by an experienced IT professional.
Common Types of Computer Viruses
There are thousands of computer viruses that your device can contract from the Internet, however, some are more common than others. That being said, all computer viruses have one thing in common: They need to infect multiple programs in your computer to operate.
What can a computer virus do?
