I doubt I am the only one to have found this but I am amazed at the lack of reference to it on the 'net. I cleared the system of this threatware by identifying the offending file (called fab.exe) and removing it. No problem - but on restarting the machine I find that no com or exe files will run at all. All I get is the Windows box Open With... Some windows files work but not all. The problem means that things like restore, msconfig, task manager all refuse to function. Any ideas anyone?
