This program doesn't make a lot of sense. This is one remark I question:

Unfortunately, most anti-virus systems that installed on mail servers are made so, that they forward the whole infected e-mail to the sender. The virus uses your e-mail as the sender address and then you get megabytes of infected mail that was intercepted by the anti-virus. I-Worm.Sobig.F Virus Stopper now detects and deletes «undelivered» e-mails that flooded your mailbox after such «cure».

If it's resident on your computer, how is it going to stop undelivered email on the email server? You aren't going to install this on your ISPs server. I suspect this doesn't acurately describe what it really does and I question if it does anything. I'm doing just fine with my Norton Antivirus, my spam guard setup at my ISP, and common sense.
