Update antivirus software regularly; it is important to regularly update virus definitions in order to better protect computers from virus, malware and spyware attacks. One can easily set schedules when the computer will automatically update its antivirus.

Delete the temporary files from time to time – temporary files are files downloaded into the computer whenever an internet surfer visits a website. It helps recently visited sites to open up quickly when revisited. Though these files are often tiny, in time these files can accumulate and can pose a problem.

Always remove unnecessary files; unnecessary files often take up a large space in many computers. Files that should be deleted are often left stored in the computer until it is forgotten. It is also a good computer maintenance practice to regularly delete the contents of the download folder and the recycle bin.
