Gain / Gator / Claria Removal

Overview: By far the widest spread form of adware. Claria is known by a number of names such as GAIN and Gator. Claria is the latest name change for a company that is very widely hated (all adware, spyware and malware companies are hated). Tons of "Free programs" install some variant of this ad serving software on your system to make that developer money. This approach to offering free software is NOT something that I currently or ever will approve of.

Class: Adware

Removal Instructions:

This ones really a pain to remove manually so I highly suggest either using ad aware or spybot search and destroy for this one.

Destroy Autorun:
Delete this key and then reboot
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\cmesys

Also make sure you click start --> Run and type in msconfig. Then select the startup tab. Any references to:
gmt.exe
fsg_4104.exe
cmesys.exe
gatorstubsetup.exe

End these Processes:
gator.exe
guninstaller.exe
fsg_4104.exe
gmt.exe
cmesys.exe
gatorstubsetup.exe
NOTE: you may have to replace C: with whatever drive letter your OS is on.

Unregister These DLLs:
Tip: this is only a list of known files/locations. You will want to do a search by the name of the file to see if they're on your system.
A while back I wrote a guide to Register/remove DLL or AX files which you will need if you don't know how to unregister these files.

That's It

If you've decided to remove this pest manually you should still scan using ad aware and/or spybot to make sure that every last piece has been taken care. Also if you have this one then you quite possibly could have more that those spyware applications would be able to find.
