Hey TSF!

Im new to the site and just read through the 5 steps before posting a log. I've spent the past few days cleaning off my computer, and boy did I need it. I read in the posts that you should only have 1 antivirus installed, I was curious if there was any one that is recommended above the rest. At the moment I have Symantec Endpoint Protection, Avast, AVG, Spyware Doctor, and AntiVir Classic, along with quite a few cleaning utilities (all from MajorGeek.com). I thought that having more would be better, evidently not, as my system resources are being drained from all of them. Any suggestions?
Thank You!
