Add Contact Block What is the best free antivirus software?

I have McAfee Security Scan Plus. I just installed that last night. I don’t have any other antivirus software though. It keeps taking me to the Mcafee home page and wants me to buy their product. Does McAfee have a completely free version? ( Free to scan and free to fix and remove the viruses.) Or what are some of the other good free antivirus programs? Thanks

Usually, all the paid virus protection software will allow you free service for at least a month.  Then you have to purchase it to continue using it.  I’ve heard AVG has a free offering.
