panork,
Thank you for visiting the Microsoft Answers community forum.
What is the web site? Are you sure it is .swe and not .swf or .swi? The latter are both file extensions for Flash animations, which are very commonly found on many web sites. But .swe is not very common. Here are the only known uses for that file extension:
NHL 2002 (hockey game)
Personal Paint user interface file swedish language
SendaWin etiquetas labels
Sweater Wizard knitting pattern
Sweden localization language file
Any time you find a file extension that you do not have the program to open, question it and look it up on the Internet before you attempt to open it. It could very well be a virus.
Hope this helps.
Thanks,
Gloria
