How many times do you perform a scan to your computer to check for viruses?

i don,t think so, in my pc i am not using any antivirus because any antivirus may slow down your computer. my pc works very smoothly without antivirus. i don't know how any person's pc getting harmed with viruses. i use my pc from one & half years and without antivirus and i don't think my pc getting slow or some my data is being loose in this period. so think about it and have a nice day.

Our computer is done automatic to scan once aday as well as each time we turn to computer on it is done,so far we have had no problems.All i can say is i know there are alot of virus problems being sent on facebook at the moment.

I perform a scanning process on computer..very often.. i don't try it daily.. but 2 times in a week i performed this process..

I never scan the computer on my own. I just keep the scanning on automatic mode. It then scans my system automatically. It shows warnings only and I never make me a reminder in my head to scan my hard disk.

i have installed e scan antivirus, and in 5-6 day, it remind me to check for viruses,and do quick scan of important documents, plus i do scan in 15 days time..
and when i connect to internet, every day its get updated on his own..

My antivirus scans each day on its on at a certin time. I also perform a full system scan on my own 3-4 times each week.

I scan my computer when I have connected to internet and downloaded something.
I scan my computer when I connected a flash drive which was connected to other PC that i do not know if infected with virus or not.

To put it simply, I only scan my computer every time it is connected to other networks such as internet and media transfers from portable devices, USB drives CD etc.

we do a quick scan every day and a full scan weekly

I never scan my compuer until it run slowly or has a problem. I have installed the antivirus software. When there is a suspicious program, it will warn me to deal with.
my computer works well and I think it is not necessary to scan it frequently.

I have Windows OS in my PC. Compared to other Operating systems like Linux and Mac, the Windows has very good chances to get infected easily if I do not install an updated antivirus.
I have installed AVG free in my PC and I update that on regular basis. I have configured the settings so that it scans my PC thoroughly once in a week. This is an automated task and it runs in the background so I do not have to halt other works for it. Otherwise whenever I get any file from outside, I always check before installing or copying to hard disk. I am really scared with the .exe, .zip, .rar,pen drives and those sites which easily infect computer when they carry virus.
