If a virus program is present in your computer the antivirus program when loaded checks whether it is present or not.It further checks which part of the disk is infected by it These detectors alert the users with the presence of virus. A message is displayed on the screen telling the user that system is being infected by the virus or not.

Once the virus is detected it should be stopped to replicate itself.Moreover the virus which is already present should also be removed.Some steps to prevent your computer from viruses:
- Maintain a strict security level for browsing the Internet.
- Never download data from unfamiliar website.
- Scan your computer thoroughly on a regular basis.

The antivirus program prevents and controls the damage from the virus.Once it is loaded,the antivirus keeps a copy of boot sector information, FAT's etc. and stops the applications to execute when the virus tries to replicate itself.Thus, no further damage is caused.Whenever a virus activates,antivirus stops it from spreading and generates a message whenever it is found.So, it is good to install an antivirus program as early as possible.
