Because XP will not always show you hidden files and folders by default, Go to Start > Search and under "More advanced search options".
Make sure there is a check by "Search System Folders" and "Search hidden files and folders" and "Search system subfolders"
Next click on My Computer. Go to Tools > Folder Options. Click on the View tab and make sure that "Show hidden files and folders" is checked. Also uncheck "Hide protected operating system files" and "Hide extensions for known file types" . Now click "Apply to all folders"
Click "Apply" then "OK"
Now find and delete
C:\Program Files\Viewpoint\Viewpoint Manager\ViewMgr.exe from folder
C:\WINDOWS\assembly\temp\mainiis.exe
C:\WINDOWS\Web\Ers_src.htm
Also in safe mode navigate to the C:\Windows\Temp folder. Open the Temp folder and go to Edit > Select All then Edit > Delete to delete the entire contents of the Temp folder.
Go to Start > Run and type %temp% in the Run box. The Temp folder will open. Click Edit > Select All then Edit > Delete to delete the entire contents of the Temp folder.
Finally go to Control Panel > Internet Options. On the General tab under "Temporary Internet Files" Click "Delete Files". Put a check by "Delete Offline Content" and click OK. Click on the Programs tab then click the "Reset Web Settings" button. Click Apply then OK.
