I use Avast Antivirus, it is the best. It is free and really simple. This one never disappointed me untill now. I recommend it to you all. Thanks, hypeeeeer
I use Norton 360. It is not too expensive It tunes your PC's performance. Detects risks immediately. It also backs up your files to a secure online storage(2 GB is free) Hope this helps.
Av alone is no good. Install SpyWareBlaster, Spybot, Adaware, AVG, AVGAS, CCleaner, Spysites, and I think 1-2 others.
I use AVG Free version. I am pleased so far with it. Great program + it's free. In addition to it, I am using Zone Alarm which is the best firewall ever.
I use NOD32 V3. It works ok,but after long time it starts to eat ram. I am not an adult website surfer or looking for warez that is why i don't meet viruses often,but it happens.
Kaspersky Internet Security. The best, cheapest, and least resource hungry. Norton and Symantec are terrible.
