Hi there:) Having scanned my system there were 3 rogue.installer files (same file) detected which I believe may be fps. I checked the setup.exe file with Jotti Online and all seemed ok. I am hesitant to delete these three files in this hidden folder, as I believe that it may contain the information to uninstall several programs. I should maybe point out that the $ISR relates to backups I use with the program First Defence-ISR. Can you possibly advise me should I delete or not? The three possible fps refer to 3 copies of that same setup.exe file. I believe that the setup file may possibly relate to an online game that I play called Conquer Online although I am not 100% certain. I found the reference to B6060381-5C28-4F86-A31A-B5ADA7A1BD8D in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall. There were references to the game Conquer Online in the right hand pane. The date of the setup.exe file would also appear to correspond with other conquer files that I downloaded:- Malwarebytes' Anti-Malware 1.28 Database version: 1230 Windows 5.1.2600 Service Pack 3 05/10/2008 21:47:07 mbam-log-2008-10-05 (21-46-58).txt Scan type: Full Scan (C:\|) Objects scanned: 253160 Time elapsed: 2 hour(s), 22 minute(s), 43 second(s) Memory Processes Infected: 0 Memory Modules Infected: 0 Registry Keys Infected: 0 Registry Values Infected: 0 Registry Data Items Infected: 0 Folders Infected: 0 Files Infected: 3 Memory Processes Infected: (No malicious items detected) Memory Modules Infected: (No malicious items detected) Registry Keys Infected: (No malicious items detected) Registry Values Infected: (No malicious items detected) Registry Data Items Infected: (No malicious items detected) Folders Infected: (No malicious items detected) Files Infected: C:\$ISR\2\Program Files\InstallShield Installation Information\{B6060381-5C28-4F86-A31A-B5ADA7A1BD8D}\setup.exe (Rogue.Installer) -> No action taken.
