I'm very cautious about security and I scan my PC daily (sometimes couple a day). First I do Mcafee Virus scan, followed by 'Spysweeper' Scan. After that I do 'adaware' scan and at the end 'Spyware Doctor' scan. Scanning finished now then do some usual hard drive de-fragmentation and drive medic etc What about you?
I let AVG scan every morning while I'm making coffee. I make daily backups to a separate drive, and weekly backups to an external drive that I keep 'offsite'.
I scan every day and i use only AVG but i am getting alot of trouble of pop windows recently eeven though i have pop up windows blocked!
I normally scan my pc and laptop once in a 3-4 days with my AVG. And use AVG scanner everytime for downloaded zip or rar file before going to open it.
Daily is a bit extreme But I check it for viruses and other animals once twice a month... Just did yesterday in fact
I like to scan it once a week using AVG and Spyware Terminator, but I always do full scan everytime my brother use my PC. I don't know what is he doing,but my PC always full of virus and spyware after he use it
About once a month, I scan my PC with a couple different antivirus programs and 3 anti-spyware programs. The combination usually kills anything on there.
Once every ten days. However, if I visit a suspicious site,download something that I don't trust etc, I scan immediately after it is done. I am very careful about which sites I visit and what I download. I have never really had any problems in last couple of years.
