Answer 1

Answer:

☆Preventing virus infection

↳The following is a list of the do's and don't for preventing virus infection in a system.

✦Avoid booting the computer with a pen drive. If it is required to boot from a pen drive, use a virus free pen drive.

✦Do not exchange the disks or one drives with other. I'd you do so, always scan the disk or pen drive with an antivirus software before using it.

✦Do not use pirates software. If the software has been obtained illegally, it may contain a virus.

✦Always keep at least one set of backup copies all original disks. This does not prevent virus infection but it helps in the recovery process if a virus corrupts the data.

✦Always keep the Auto - protect, Internet -worm protection and E- mail scanning features of an antivirus software on to prevent downloading of the infected files.

✦update the antivirus software frequently so that it can detect and delete new viruses.

✦Always check if the computer demonstrates any strange behaviour like :

✦ slowing down

✦ dispperance of files

✦ taking longer to load programs

✦ presence of unusually large sized program files.

✦ decrease in the freezer space available on the disk

✦ recent creation dates on old program files

✦ unusual display on the computer screen.
