Last night mbam quarantined one file with Trojan.Backdoor.MRX. I read about the false positives on this forum, and that the problem had been solved in the new database, so I updated the database and ran a full scan overnight. However eight more detections were found. 1. If these really are false positives, why am I still getting detections and what should I do next? 2. On the scan result screen, does remove mean quarantine? Since I don't need these eight files, I'm inclined to remove them even though this may be a false positive. My options are remove selected, ignore, save log, main menu, exit. If I remove them does it just delete those files or does it make changes to the registry as well that I might regret? 3. I would look at the mbam help files but I'm concerned about navigating away from the scan result screen. Other info: I also run Eset NOD32. Yesterday, before these detections happened, I downloaded a free open source utility called winmerge from winmerge.org via sourceforge.net. Although I tried to check it out before downloading it and it seemed safe and well reviewed, it makes me very wary since I have never downloaded an executable, at least not for many years.
