I am a computer tech, and I HIGHLY recommend AVG free edition.. my customers love it, my family uses it. I use it and love it and wont even think about taking it off!!...

Avg Is better in system departament,it is not big,eats lesser ram then kaspersky,but in wirus departament, kaspersky is the bes av for all,if u have a very good cpu with at least 1gb ram,use kaspersky, but if u have less use avg

Just try on Kaspersky..it works very good in mu system and catches all virus...

I recommend AVG Free Edition. I use it at work on all 30 computers, haven't had a virus since.

i hate to put my 2 cents in but i have used AVG anti virus and never had a virus it did not catch and remove

Well, its the proffesional version that removes viruses, otherwise you have to google the virus.

What good is it if it can't remove the virus it has located...and also I thought that this thread was for FREE anti-virus programs....pro versions have to be bought and paid for.

i am not sure we are talking about the same software. there are 2 versions of the software, 1 is free and the other is the commercial version. i just had a problem with a virus and avg caught it and I removed it. i downloaded the software from "downloads .com" and the avg site and both worked the same way AVG keeps the virus in a "Virus Vault" if you go there you will see all the viruses it caught. if you want to delete them double click on the avg icon and that opens up the test center window, then click on "virus vault".highlight the virus in the window by right clicking on it,if you have more then 1 hold down the "shift" key press the down arrow buton to highlight them all, go to "action " button on the avg task bar ,select delete files and they get deleted. you have to look at all the files to make sure you are not deleting a file you need .there are other choices like "heal file", "restore file". just make sure you don't delete a file you need, but if it is a virus it will state it , example "trogan file etc" highlight it and delete it. if you don't feel comfortable deleting the file just set up a "restore point" in windows and if it was a file that is needed you can always restore the computer to the point that you picked before you deleted it. i have never seen any files in that vault but virus faults and never had to restore my computer. i hope you understand all of this. i am a 2 finger typer and my 2 typing fingers are cramping up.LOL if i have put down some wrong info someone who is sharper then me will let us know..gotta go now--bye

I think he might have been talking about older versions of Avast.
From Avast website.
"Since version 4.1, avast! includes the Virus Cleaner, a tool designed for a complete removal of most common infections from already-infected computers. So now is avast! capable even to reliably heal (not only detect) the most common malware."

Most virus scanners have some type of Virus Vault or Quarantine system. Not all virus's can be removed or cleaned. So if a virus that can not be cleaned replaces a critical system file with it's own it can be quarantined until you can find a solution.

On a related note..
Recently my Avast portable version ran out so I was looking for a new free portable virus scan engine. I just installed ClamWin Portable on my USB drive and ran it on a computer that was thought to have a virus infection. It found 14 infected files. My other scanner detected none after running ClamWin Portable. I'm not to confident in it just yet though. Maybe someone else has some experience with the Clam Engine. It's easy to run from a CD also, which I like.
