Howdy all, Just got back from Uni, and have the privaledge of trying to clean the home pc from the delights my little brother has managed to install while I'm away. Seems to have got a corker on there... This particular one manages to kill a command prompt as soon as you start one, along with firewall, antivirus, spyware, taskman and anything else useful. Searching for adaware and similar terms in IE causes the window to close. A quick glance reveals some suspicious files: wincrtad.exe and wincrtalt.exe, but unable to remove as they're in use by system... grrr So questions: Are there any system commands to kill processes from the command line, and does anyone have any experience/ideas? Should I just give up and format? Cheers !
