Just got an e-mail telling me my McAfee licence has expired. Gave me a button to click to renew (which no doubt would request bank details). Also added a warning to say there are 39 viruses on my machine.
Only two snags.
1. I don't have McAfee on my machine and never have had.
2. The e-mail address it came from is [email protected]. Doesn't sound much like McAfee to me.
