I have noticed that every time I boot up my Norton Anti virus finds a so called Trojan in my Windows\System 32 folder. It is always something like this IDE82D.tmp. There may be different numbers and letters, but they are always close to the same. Does anyone have any idea what program might be loading these up. Thanks

Sounds like you need to boot to safe mode, then run the antivirus software to remove the files. From what you are saying it sounds like the virus protection removes the trojan, than something rebuilds it during a restart. Boot to safe mode by pressing F8 after your bios screen and before the windows logo screen and then run the antivirus. hopefully that will permanently fix the issue.

Have you tried any spyware/malware removal software, i.e. Webroot Spy Sweeper? Or you can use Stinger (http://vil.nai.com/vil/stinger) to do a scan on your system.

Yes I have several anti spy software programs. They find nothing. Also Norton gets rid of the file but the next time I boot up there is another one by a different name in the System 32 folder. So I don't know what might be loading them up. They always get wiped out by Norton, but I don't know what program is loading them.
