How does a free antivirus program work?

An antivirus program is a software that is specifically designed to look for, detect and delete computer viruses and other software that might be harmful to your computers like Trojans, adware, and worms. Antivirus programs do a great job in preventing and stopping harmful programs before they find their way into your computer and cause damage.

The truth of the matter is hackers are getting smarter by the day and are developing ingenious ways of planting these viruses in your computer, which is why you need a free antivirus program to stay a couple of steps ahead of them.

Antivirus software does its job simply by continuously scanning code or files that are incoming through your internet connection. Antivirus software companies possess a huge and ever-growing database of known malware and viruses that are used to flag, detect and sometimes remove these viruses from your computer.

When a match is found, it is automatically detected as a virus and is automatically isolated pending further action from the computer user.
Most free antivirus software does come with an option of adjusting your action settings like automatically scanning your computer for dangerous files whenever you connect to the internet or manually turning on the scans which allow you to monitor in real-time as threats are detected or neutralized.
