Did you remove eset? Also, I'm surprised you think Avira is slower than eset. Eset was one of the worst I had ever seen for a long time. If you're going to go with a paid antivirus, you need to look at Webroot or Kaspersky. Fastest two AV's on the market. Non-paid, Carnage can give you the best options there... *performs Carnage summoning spell*
