I'm searching for a powerful antivirus, what is the best antivirus?

That depends on if you want free or to pay, what you want it to do, (pure antivirus or part of a bundle) %26 how much control you want to give it.

I personally recommend VET/Computer Associates (same program different name depending on country of origin) for a charged combined with either AVG or Avira (both free).

Can use AVG %26 Avira together if looking for free only.

Avoid PCCillin not very friendly to other AVs %26 hard to twin

a large list of free %26 non free AV's (with links) is on http://www.freebyte.com/antivirus

AVG makes a good free antivirus

Norton Antivirus is good if ya want to spend a little
Norton 360.

Windows Advanced Care , This tool will keep you computer running good and you can see the startup programs to help you understand what runs in the startup programs; It also imunizes your computer against the attcks we face each time we go on the internet Just run it once a day and your worrys are much less,
