What is Anti-Virus Software?

Antivirus software is a set of security programs you install on your computer or mobile device to protect it from getting infected by malware, is designed to detect, prevent, search for and clean up computer viruses and other malicious software like worms, trojans, adware, and more. Which may attempt to infect your computer system. Is a type of utility used for scanning and removing viruses from your computer. While many types of antivirus (or "anti-virus") programs exist, their primary purpose is to protect computers from viruses and remove any viruses that are found.

There are several ways that your system may become infected. The most common way a virus is spread is through infected attachments to email.

Although details may vary between packages, anti-virus software scans files or your computer’s memory for certain patterns that may indicate the presence of malicious software

Since new viruses are constantly being created by computer hackers, antivirus programs must keep an updated database of virus types. This database includes a list of "virus definitions" that the antivirus software references when scanning files. Most anti-virus programs include an auto-update feature that permits the program to download profiles of new viruses.

While antivirus software is primarily designed to protect computers against viruses, many antivirus programs now protect against other types of malware, such as spyware, adware, and rootkits as well.

Once you have installed an anti-virus package, you should scan your entire computer periodically by Automatic scans or Manual scans. Most antivirus programs include both automatic and manual scanning capabilities.

Antivirus programs are essential utilities for any computer but the choice of which one is very important.
