1. The new AVG “sheur.xxx” engine is well-known for a large number of false positives. It has been released just recently, and is not quite ready for the prime time. See e.g.

    and many more.

  2. I’m quite sure RunScanner is a legit application. It is published by a Dutch guy called Moernaut (http://www.moernaut.com) and the setup file is even digitally signed.

  3. There’s no reason to argue on this forum, especially about “who knows more about antiviruses” and the like. Please stay on-topic and follow the forum rules.
