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.
