this is a guide to get rid of GAIN/Gator if it is on your computer
Navigate to the Start Menu > Programs > GAIN > About GAIN
When the About Gain window opens, click on Diagnostics tab then click on the 'Click Here' link to shut down all Gain/Gator components.
Now if you don’t have that listing in the programs menu then open the task manager and close programs by the name of GMT and/or CMESys by highlighting and clicking ‘End Task’
Once closed delete the CMEII&GMT folders in Windows Explorer:
C:\Program Files\Common Files\CMEII
C:\Program Files\Common Files\GMT
Only delete the CMEII and the GMT folders and their contents, nothing above them. Those redundant and annoying ads are now gone, that is until you install another program that uses GAIN/Gator Ads.
