Here's another exploit that was recently in the news.

http://www.microsoft.com/technet/security/bulletin/MS10-046.mspx

This one was triggered as soon as Windows generated the icon for a 
shortcut (.lnk) which means that simply exploring a USB flashdrive or 
clicking a link to an Internet webdav directory could compromise your 
system without even opening a file.

The way I see it, the worst case potential cost of infection is 
catastrophic.  Once your system is compromised you could lose your 
files, have your identity stolen, bank account drained, etc.  Whereas 
the cost of running one of the many free anti-virus on Windows machines 
is a few CPU cycles and 50 or so MB of RAM.  Granted, no anti-virus is 
perfect and can't save users from ID-10T errors but if it prevents even 
one exploit then it was worth it.
