Frequent detections of Win32:Sality and Win32:SaliCode after last update

Avast just updated to the latest virus database version, but since then it has been detecting Win32:Sality or Win32:SaliCode in almost every downloaded installation file - including the legally downloaded ones.

For example, if I try to install MP3Tag, IrfanView or Silverlight (which are all downloaded from their original locations), Avast constantly detects one of the viruses mentioned above.

I personally believe it’s a false alarm… Any thoughts?

Avast: 7.0.1474 (latest)
