At about midday today my wife went to check ebay for information on an item she had recently purchased, and she did this using my office computer.
The description that Thomas gave of his experience was quite similar to what happened here.
The message seemed to indicate that it had been sent by Microsoft and suggested that you phone 1800-401-618 for assistance in removing the supposed virus.
I immediately unplugged my computer from the LAN and downloaded the latest version of "Microsoft Safety Scanner" to a memory stick using another computer, transferred the stick to my suspect computer and ran a full scan. No problems were detected. I have also run other virus checks but these also failed to find any problems.
I strongly suspect a scam of some sort.

I also have this alert (as of today) when I open Firefox - it repeats a computerized voice warning telling me to call this number because my computer security is at risk, as well as showing a log-in box asking for my password.
Clearly a hoax but there's no way to shut it up.

While using computer, a notice appeared on screen, "virus has been detected, call Windows help desk on 1800401618 immediately" could not delete message, had to turn off computer, Windows help desk number is different from the one displayed on the message. I ran a virus detector and found nothing, I believe it is a scam.
