free online scanner and cleaner
free is not as good , Norton when purchased on sale with a rebate is almost free, No company can provide software Plus maintain a staff to keep it up to date for free and if it is not up to date it is not worth having
try www.avast.com for a free virus program
Check out a program called Avast! The home version is free..

There are actually quite a few options of free anti-virus software out there. I'm not sure if any of these come with Spyware. The open source or GPL software will not. And panda activescan(which is a cool web virus scanner) does not. As for the efficency, freeware/opensource can and sometimes does compete with it's corporate counterparts. Panda software is a commercial company which also gives it's activescan away for free so you know you have the latest virus protection. It doesn't automatically run on your computer however, so it might be better to combine Panda with one of the opensource/freeware AntiVirus applications.
