I ran Avast! Home Edition after updating to the newest version yesterday and it found something called HTMLcript.inf and WinRPoly [Cryp]. After some internet research, I found several posts on Ubuntu/Linux forums of the HTMLcript.inf being found by AVG Free Home Edition only for the poster or respondents to determine that this is a false positive by AVG. Unfortunately, these posts were for Ubuntu/Linux systems. My systems is a Windows XP SP1 system. Turning to Daniweb, I searched for the HTMLcript.inf in the forum threads. I found indications to download and run Malwarebytes. I did so and following is the log. I did not have it remove any infections yet because I do not know if it will make a backup in case I need to restore any file. Help on the Malwarebytes log and what to do with the HTMLcript.inf and WinRPoly [Cryp] infections is greatly appreciated:
