go to symantics site and use their uninstaller utillity. It should remove it.
If not download the utillity "unlocker" unlocker will free the application and allow its removal through the control panel add/remove application.
Then use Ccleaner's reg cleaner application to remove any remnents of the files and any other files that you have been removing.
If you are willing to take the chance...shut down "system restore" then go to trendmicro.com and navigate to the free virus scanner...run the scanner (must install an active X) and it will remove most of the issues from the malware/spyware/virus/trojan.
System restore must be shut down so the scanner can read the files.
