I have recently worked on two PCs that crashed because of the virus. In both cases I managed to salvage the hardware, but only by reformatting the hard disk and losing everything on it. Sometimes the BIOS is corrupted and then bye-bye computer. These people were very active on email - goodness knows how many other peoples' machines they've corrupted. I have no idea whether they had any bank account/eBay/Paypal details on those computers, but if so it's more than likely that someone else now knows their logon and password particulars.
This thing is not a joke, a mild irritant. Read the press - it is a serious threat that costs real money, and is currently getting worse. It's the people who laugh it off who are most guilty of spreading it.
Someone gave me a file on a memory stick last week. I plugged it into my computer and immediately got a virus warning. When I scanned the stick I found 38 viruses on it, many of which could cause major damage. What was particularly worrying was that the stick came from a respected Belizean professional business, and likely all these viruses were on their computers.
