Yet another strain of spyware going around the net. This one pops up windows with a variety of titles and URLs such as:

Fling.com
Fubar.com
System-defender.com
Boomj.com

After running my usual list of cleaners that I use for removing adyieldmanager, I found that I also needed to run Malwarebyte’s Anti-Malware program which you can find here:

The system I was cleaning showed a lot of trojan.vundo infections. I ran Mal’s program twice and that seemed to clean it all up.
