Are There Any Kitara, Banner Connect Users?

I started using both companies on one of my high traffic sites and within days I started receiving complaints that users were being infected with that malicious adware that installs the "fake virus protection" program that overruns your computer.
I had to remove both companies until I figure out which is the culprit. I searched on Google but found that both of them have been plagued with these issues.
Is anyone using either of them? Any similar issues?
