First off, this is my first post so I may have missed something, if that may be the case my apologies for that. I tried the following steps on the file but I accidentally pressed "Ignore" and now I can't get the malware warning back. 1. Click the Start Menu. 2. Click Run. 3. Type in "mbam.exe /developer", without the quotes. 4. Run the same type of scan you did before and save the logfile and post it. It's all about "Portable Virtualbox", the .exe which starts the program and the .exe which starts the portable virtualbox installer triggers a (false?) malware warning. You can download the installer here: http://www.vbox.me/ This is the direct link: http://files.vbox.me/files/Portable-VirtualBox_v4.1.14-Starter_v6.4.9-Win_all.exe The file you will download: "Portable-VirtualBox_v4.1.14-Starter_v6.4.9-Win_all.exe" does NOT contain a false positive. However if you run the the exe: "Portable-VirtualBox_v4.1.14-Starter_v6.4.9-Win_all.exe" you will end up with a folder where one file triggers the (false?) warning (marked red): \Portable-VirtualBox\data\ \Portable-VirtualBox\source\ \Portable-VirtualBox\LiesMich.txt \Portable-VirtualBox\Portable-VirtualBox.exe \Portable-VirtualBox\ReadMe.txt AFTER you install portable virtualbox (by running the red marked file), you end up with a directory above but with added files and folders. The RED marked file will still be there but AFTER installation it will not launch the installer but portable virtualbox itself. Thank you
