User Comments

It was installed with Windows 7 updates, most likely SP1. After updating I have a new file called Webcheck.dll v8.0.7601.17514, version date: 11/20/2011 -- the same version as iexplorer.exe (since I have IE8.) This was not in my Winpatrol startup items before updating to SP1. It does appear that webcheck.dll is a part of every Windows version, but having it start up at boot was not necessary. I am deleting registry keys that start it: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WebCheck] "LoadLCE"="no" "LoadSens"="no" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ShellServiceObjectDelayLoad] "WebCheck"="{E6FB5E20-DE35-11CF-9C87-00AA005127ED}"

Obviously its a Windows file, however this file is one of the more common system files to become infected or replaced with a malicious version of the file as it does not damage system stability when altered allowing malware authors to make changes to the system quietly.
slows down the system
Absolutly nothing. However, my Norton AV or Spyware Doctor has not dected anything wrong with this file so I assume that this file is safe.

malware, browser spyware
This files does pretty much what is says it checks websites. The main use is in activedesktop whcih I dont think i've seen any one use after fixing about 2000 computers. all the default sites dont wrrk anyway. Just a few others programs use it like some old stock ticker programs. If you have the autoruns programs you see it has the most entires for a program you never use.

This startup-feature appeared in my system after that I installed Aignes WebSite-Watcher v4.31 that claims to keep an eye on functional or broken links in bookmarks of Firefox or Favorites in IE7.
