Virus Foolishness!

It has come to my attention, after receiving about a year’s worth of email and news updates from Radiohead fans, that you are some of the most computer-savvy fans around. Which tells me that if you were to get an email like this-

Dear user of (or whatever your ISP is),
Your e-mail account has been used to send a huge amount of junk email during this week.
Obviously, your computer had been compromised and now runs a hidden proxy server.
Please follow instructions in order to keep your computer safe.
Best regards,
The (or your ISP) team.

you would
A) realize that we would never refer to ourselves as “The team”
B) realize that we would word any email about something like this in a far more clever manner,
C) know way better than to open the suspiciously named ZIP file at the bottom.
Just making sure.
PS- There’s always a tradeoff. If you buy a Mac, you don’t have to worry about this stuff. But then, you can’t run SoulSeek, either. What to do?
