I maintain the computer of a long time AOL user that is limited in computer skills. She still uses the AOL browser that downloads files on the hard drive before opening them. Today she had a System 32 error and I just made a new image using Acronis. I have Microsoft Security Essentials and SpyBot Search and Destroy installed. Is there a good Antivirus and Spyware program that does not bog the computer down but updates automatically and needs little user input?
