I have been dealing with cleaning up several family and friends computers from Viruses. The majority of time they have a commercial program that is just not getting the job done. There are several great antivirus programs and several not so great programs on the market. The majority of the general computer population is unaware that there are a couple free options that offer great protection. Below are the three that I highly recommend if you are looking for a free antivirus solution. They are in no particular order as each of them has their pluses and minuses.
- Microsoft Security Essentials (Free Version Only)
- Avast (Free And Paid Version)
- AVG (Free And Paid Version)
