I run Malwarebytes myself, and sometimes run AVG scans if I do think I have a virus. Only bad thing about AVG is that it's a resource hog if you turn on real-time protection, slows my machine down, so I turn that feature off. I did purchase a full license for M-Bytes but I ran for free for a couple of years. It has a good real time protection of it's own. I mainly let my DSL provider's filter do most of the security, and periodically sweep using AVG Free and Malwarebytes. You of course know that none of the AV software defeats the pirates bad work all by itself. I like M-bytes and AVG free(w/o the resident shield.) Do your updates though. martin
