Function Key Attachment
What is Function Key Attachment?
This is a WinCheck/CMI (variant) adware/browser hijacker variant that injects code into the user's web browser (IE, Chrome and Firefox). It is known as an ad-injector, a malicious process that once inside the web browser will hijack existing advertisements of underlying web sites (not associated with the website itself). It will also inject new ads in white space on the site or images that have standard banner sizes. These ads are typically for promoting shopping discount coupons, ads for PC optimizers or bundled PUP offers, or malvertising since it runs on sketchy ad networks.This runs as a startup process called WinCheck in the user's startup registry (Run key) and will execute each time the computer is restarted and the user logs in.
How do you know if you are infected? First, if you have this program installed then this adware is most likely still running. Next, you see ads in the browser that say something like "Ads by WinCheck".
