How can we make computer virus free?

If we are not using the internet then there is no question of virus. Like malware, adware, trozen ware are placed in the form of virus in our computer. So we have to kill them by a powerful antivirus. And coming to offline, we do not plug in any infected pen drives, memory cards or any other memory sticks, they carry the auto run files.

most people will re-format the computer. I might install others anti-virus try to delete the virus.

One of the best way to make computer virus free is to have a good antivirus and to put all the data back in DVDs. Never browse or download from sites that you do not trust. Always have a good antivirus and update the antivirus once in a while.

Hi, i use a Escan antivirus software and it shows up as soon as some virus starts to get in to my system.It definelty asks what to do block or allow so if on time we dont do anything then the virus is either blocked or it attacks the computer so then it pop ups saying critical time and system is to be scanned .So i do the scanning so that the virus is deleted. You try using a good antivirus software .
