I'm currently receiving about one virus/worm a day through email, mostly Klez variants. I think most are from Crypto++ users who put my email address in their address books. Of course I use virus scanners, and anyway read my email on a Unix shell account so it doesn't affect me personally.
However, I'm concerned that even Crypto++ users, who presumably care more about security than the average person, are being infected with common viruses. If you do not currently use a virus scanner, please get one NOW. I personally use Norton AntiVirus, which you can often find on sale for free after rebate. I've also read good reviews about AVG Free Edition, which as the name indicates can be downloaded and used for free. You can get it from http://www.grisoft.com/. I also suggest that if your company or institution does not have security measures in place to protect against viruses, to ask your system administrators to set one up. At my workplace, we have virus filters on email servers, and also have Norton AntiVirus Corporate Edition on each machine.
