Had a very bad time removing it from my machine. In a fit of madness I deleted all files associated with it which proved to be disastrous. My son finally got a file that removed it. I had PREVIOUSLY sent an email to them
about how difficult removal was and how it had corrupted my machine. They sent me an email with remove.exe. They said this would re-install it. I wouldn't re-install it if some one put a gun to my head. Since the email i received from them I've also received some nasty virus's, WORM_KORGO.V,
BKDR_SDBOT.AC & TROJ_MADTOL.A to be exact. I've just downloaded the latest virus definitions form Trend Mucro and they won't remove them. How can I get this stuff out of my machine?
