Firefox always launches new window with AdsBy Plus-HD-4,8c

[StarsCoach]

Every time I launch Firefox and click anywhere on a page, a new instance of Firefox opens which appears to contain links to Adware. In the upper right of the window is the text "Ads By Plus-HD-4.8c" and over 50% of the links have this reference in them.

One example that contains Plus in the link is: https://nps.noproblemppc.com/npsb/logic ... 2511000000

Two examples of the other links is: https://secure.ciuvo.com/media/bookmark ... row.min.js AND http://www.google-analytics.com/analytics.js.

In my opinion it is a dubious program which is not very effective compared to others with a proven track record and I would not trust all the detections provided by its scanning engine. ...

@therube, based on your latest reply I've removed that post as spam (also note it bumped a 3-month-old thread).
