Ok, just in case that somebody runs into the same problem. It is not
advised, to add "<script" keyword to Forefront as it can cause problems with
SharePoint from a various reasons. Also, you cannot apply keyword filter to
specific file types. To prevent Cross-Site-Scripting you can do following:
1. Upgrade to Internet Explorer 8. Internet Explorer 7 and older are
affected and nobody at Microsoft could assure me that there are going to be
patches available for. Other browsers are not affected.
2. Write an EventHandler on a Document Library, to prevent uploading bitmap
files that contains script code. It is important to check first 256 bytes of
a bitmap file - if it contains html tags, just reject it! The function that
causes this problem (Client side): FindMimeFromData()
