I cannot find adware that is installed
I had to agree to some adware to download a program I wanted, believing that I could just uninstall it later as I have done before, but this time it is very well hidden.
I have done everything I know but cannot find what is causing popup windows putting ads in my face. I have run AVG, I have run Microsoft adware, I have run Adaware, Spybot Search and Destroy, and run Panda online scan.
I have examined the running processes, I have cleaned the registry and run Crap Cleaner. I have looked in the Documents and Settings and have deleted many files there. I found one that would not let me delete it, called "gram admin.exe."
I looked in the Add Remove Programs, nothing I do not recognize.
HELP
