Grimes If located in System32 is always legit (unless Windows File Protection is disabled) Open door for unprotected computers West L Webcheck is stupid. Its an MS module thats sole purpose is to integrate a web page as your desktop background. "Active Desktop" is what it is called. If you do not use Active Desktop then you should follow this link, then decide for yourself.  See also: Link TAC If your not running a server, you shouldn't need it.

It is backed by WFP, and thus an unlikely security risk. If you do not use offline Web page caching and want to avoid overhead connected with this file, better use e.g. Mark Russinovich's Autoruns from sysinternals.com rather than delete this file. Ron Morella If the file is an old version in relaction your Explorer version, it will give you lots of problems. Page faults are the biggest. Just replace file with correct version and all is well.  See also: Link domagoj WebCheck File not found: %system%\webcheck.dll scanned with autoruns, everything runs good in IE without it by me.
