Jon,

Firstly, I would recommend that you perform an online scan to determine if you ARE infected with the Win32 Prorat.

You can use TrendMicro or Kaspersky.

If and only IF, your system is clean by the online scan, can you assume that Avast is registering a false positive.

You then have the option of going into the Avast Virus Scanner/Exceptions and adding the pathway to the “false” positive. Avast will bypass this file in all future scans.

Good luck.
