Good eyes, that there is a Mass Mail Virus. They spread themselves by sending copies of itself to everyone in someone's address book, and forges the "FROM" field so it appears to come from someone else in that address book.
If you get any attachment with the extensions PIF, BAT, REG, EXE, VBS, LNK or COM it's almost certainly
If you scan the header, you can usually find the real sender. It's sometimes good to notify their ISP, as many people don't even know their computer is infected.
It's always a good idea to have an anti-virus application to safe-guard your system. There are free online scanners from good companies like Trend Micro. If you do a google search for "Trend Micro Antivirus" you'll find their page, and a link to a free scan.
Free is good!
