Hello @AlL, I suffer elaborate Attacks on my Computers/Smartphones for years. I am not an IT professional and I have Norton, Bitdefender and Malwarebytes run on my Computers (also Kapsersky Live CD) to check for Malware. I never received any Warning that Malware/Virus was detected. Yesterday, after Malwarebytes failed to start, I decided to run a Bitdefender Scan that was positive: Gen:Trojan.Heur2.FU.ca2@a8pzswoi was detected. This file was detected in my "Parallels Desktop" Folder (please look at the screenshot attached). I searched for Gen:Trojan.Heur2.FU.ca2@a8pzswoi on the Internet, but Google showed only 2 results in Forums. One result said that it probably might be a false positive warning, due to suspicious behavior of this file. Bitdefender couldn't delete the file, so I decided to delete the file manually. The file required about 42 MB of space. I also checked the file on VirusTotal, where only Bitdefender, Emisoft and GData delivered positive results (please look at the screenshot) Does anyone had the same problem? Is this file a legitimate Parallels Desktop file and I don't have to worry about? Kind regards Alex
