Watch out for these guys, they ask you to open you computer using a joining program and then steal your personal data like password, banking information and tax records. Slim balls. If I could figure out a reverse virus I would open a slave system and blow up their operations.

Rcvd call from "ITECH" a Microsoft company saying that my PC was downloading a
virus as we spoke.  Told him (foreign accent) that I would take care of it. Hung up.
Ran full system check with McAfee (which showed nothing) and with AOL TechGuru
program. That also showed nothing...
Watch out for this Telemarketer

says my computer is infected. foreign accent.
