nod 32 and vcom systemsuite 6 (firewall and fix it ultilities. the best all in one suite out there). don't use the a/v that come with it. leave it in the background as a backup scanner, in case something crazy happens
i cant agree with the vcom suggestion , few months back ive tried it (didnt actually use it much) but after installing i noticed its incredibly resource hog it made my pc alot slower so i uninstalled it and my pc got way faster as it was before
