VBS/Freelink is an e-mail worm written with the VBScript language. Programs written with VBScript operate only under Windows 98 and Windows 2000 (unless Windows Scripting Host has been installed separately)
The VBS.Freelink virus distributes itself as an e-mail attachment. The e-mail attachment must be opened for the virus to propagate.
Run noscript from the symantec site to disable vb script and then an online virus scan.Also update your windows.
