What do you do to protect your computer from being infected by......?

I have in my computer McAfee Antivirus.

I have tried all sort of anti virus both free and paid, i used free editions of quick heal,Avg,norton,avast, an many more...........i even bought an original version of quick heal but all to no vain....... ha to format my machine in a month or two but these days i am using anti vir An i tell you it's one of the best anti virus i ever used you too should try it the next time you format your machine.

you can go to the internet to download some software to protect your computer and i do so !

I use F-secure client security (it has virus, spy, trojan, roots and system protection). I think it is better to use one program, or at the most 2, or else you risk on having conflicts or a slow moving computer with a lot of programs running at the same time.

download a spyware or virus scanner? i had mine in kapersky anti virus scanner.. =)

When i first got my com used to be hell lot of worried aout viruses....that was when i was in the 8th grade.Never used to load any cd other than the ones provided by my computer dealer.Then in the 10th grade started usin pccillin and zone alarm...! zone alarm rocks but slows down internet connection a lot.Nowadays only ESET NOD32 antivirus.... too perfect...!!!

I just use windows defender with windows vista home premium, i don't see any reason to use a bunch of software who are gonna slow my pc, i just try not to go on any harming website and when my pc get a little slow or get any kind of spyware, i format and reinstall... lol:)
