How to tell if webcheck.dll (Web Site Monitor) was uninstalled cleanly

After uninstalling, restart your computer. Then start Windows Explorer and see if there is still a folder with the name of the software under C:\Program Files.

To do this, start "Regedit", then look under "HKEY_LOCAL_MACHINE" > "Software" for Web Site Monitor or the name of the producer. Always keep in mind that only a computer professional should ever directly delete entries in the Windows Registry.
