Hi, so while doing a routine Malwarebytes Full Scan (with the lastest free version) using definition file v2013.06.15.07, I encountered an infection known as Trojan.FakeMSTT on the file "C:\Program Files (x86)\Common Files\microsoft shared\Help\msitss55.dll" Being unable to find any info on the nature of this Trojan (or the dll file for this matter), I decided to upload a copy of the aforementioned file to VirusTotal, and all scanners came back clean. This has led me to believe that Malwarebytes may have found a false positive. I have attached the log file from the scan and the affected file in a zip file for your convenience. Thanks for looking into this matter! MBAM-log-2013-06-15 (23-01-21).txt msitss55.zip
