I can just relate my 15 month or so experience with Avast Free and AIS.

  1. I am all over the Net continuously everday
  2. Besides now using AIS I use WD and SAS real time and the following programs in batch mode; Malwarebytes, Trend Micro Housecall, Hitman Pro, ESET, Dr. Cureit and even Stinger :slight_smile: by McAfee.
  3. Rarely and I mean rarely have these other programs including SAS and WD ever found any Malware, including Trojans, Rootkits etc that were missed by Avast.

That is good it enough for me :slight_smile:

AIS does what it is supposed to without conflicts with other programs, is easy to configure and easy to use.
