You aren't running Anti Virus Software

Anti-virus software are programs that detect, cleanse, and erase harmful virus files on a computer, Web server, or network.
Unchecked, virus files can unintentionally be forwarded to others, including trading partners and thereby spreading infection. Because new viruses regularly emerge, anti-virus software should be updated frequently. Anti-virus software can scan the computer memory and disk drives for malicious code. They can alert the user if a virus is present, and will clean, delete (or quarantine) infected files or directories. Please download a free anti-virus software (for personal use), from one these excellent vendors NOW:

1) Antivir PersonalEditionClassic
-Free anti-virus software for Windows.
-Detects and removes more than 50,000 viruses. Free support.
2) avast! 4 Home Edition
-Anti-virus program for Windows.
-The home edition is freeware for noncommercial user.
3) AVG Anti-Virus Free Edition
- Free edition of the AVG anti-virus program for Windows.
- Available for single computer use for home and non commercial use.

It is strongly recommended that you run only one antivirus program at a time. Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts.
