Kaspersky or nod32

Whcih is the best antivirus?free anti virus

Try Avast Home Edition, it's free. It works very well I have it. If people tell you AVG is good don't listen, it lags the system and is a nuisence.
Have to tried either Avast or AVG. Both work very well and both are free for personal use.

To stop an anti virus program from slowing your system down, do not allow it to do background scans, or boot up scans. Just run it manually every week or so, or when and if you think you may have acquired something that you feel may be nasty.

Here are the links to this software. I have included links to anti spyware and a firewall too.

All of the following are free.
