Hi, I do have two weeks problems with troj_checkin.b. TrendMicro virus scanner detects thes troj and deletes it. Also I try to delete it manualy in the register. But it comes back again. I saw also that is makes ttps.exe and owmngr.exe active and try to contact serveral sites: popunder.info.... and fastfind.org Does anyone know to get them out of my register en system for good!!
