Im floored that Avast! isnt even on the list. I use an older version of ZoneAlarm(6.5.714) sitting right next to the latest ver. of Avast! and I havnt had a virus in over a year now. Actually nothing gets through, I stopped running my antivirus software like 6 months ago because It took hours and it always came up with the same "Congratulations, your system is virus free!" or whatever that line is. I run it on three computers here. And Ive never run windows anything! Those Freaks! Nor Norton, or Symantec. Commercialized Crap. I dont even use Internet Explorer. It always seemed like I was opening a Garage Door to every virus, trojan, adware out there. Call me a conspiricist if you must but except for windows itself......if its even remotely connected to Microsoft.....SHUT IT DOWN! Bill Gates would burn his own family to know what your doing on your computer.
