Question

what are the computer viruses ?how to prevent virus from damaging the computer 5 point

​

Answer 1

Answer:

A computer virus is a form of malicious software that piggybacks onto legitimate application code in order to spread and reproduce itself.

Like other types of malware, a virus is deployed by attackers to damage or take control of a computer. Its name comes from the method by which it infects its targets. A biological virus like HIV or the flu cannot reproduce on its own; it needs to hijack a cell to do that work for it, wreaking havoc on the infected organism in the process. Similarly, a computer virus isn't itself a standalone program. It's a code snippet that inserts itself into some other application. When that application runs, it executes the virus code, with results that range from the irritating to the disastrous.

Answer 2

Answer:

A computer virus is an unwanted malware that can slow and infect your computer. If you want to prevent it, you shouldn't download files from any suspicious website, be sure not to enter trojan horse websites, and check often for malware. Though checking often might not PREVENT it, it can help stop the spread from completely destroying your computer.
