like Keri "they claim they are from microsoft, and that you're computer has been sending out messages and may be corrupted." Telling me they can fix it for me, unfortunately my computer needs a reboot and was not usable - so I hung up.
I like the others received a call. Same ID: Pay Phone. Same scenario. Virus and Computer problems. Wanted me to go to website. I told him I'd check on it first. I asked what I'm running, I told him several OS's. He stated he was blacklisting my PC. I asked him when so I could call the REAL microsoft and find out why.
