Which Anti-Virus software do you use?

If you want to use a paid version, you could try Kaspersky and Symantec antivirus. Both the two does its jobs pretty well. It scannned your computer thoroughly. For free-version antivirus, you can try AVG, AVIRA, and AVAST. Currently, I am using Avira AntiVir Personal Classic Edition. I have been using this one for over a longer period of time. Since then, I have never had problems at all. Otherwise, I am very much satisfied with it. It updates regularly and can be scheduled at your most convenient and spare time. It is very light on resources and does not use a lot of memory. Hence, does not slow down your machine. It detects and deletes rootkits, viruses, worms, etc. You can download this at www.free-av.com Hope this would help. Have a nice day!

I use avast professional. I like it better than any other out there and it was recommended by a pro in the field. check it out at the alwil site.
