Thank you for your reply. Sorry for the lack of supporting detail.
I'm running Win 7 Pro Home.
I had retrieved advice from Kaspersky (I have their anti-virus), to download and run Clrav
(from their forum, http://forum.kaspersky.com/index.php?showtopic=189675
), to no avail since
I could not run ANYTHING but IE and windows explorer.
I downloaded setup_mbam.exe according to the advice I got from bleepingcomputer (after a google
search, I found this advice at http://www.bleepingcomputer.com/forums/topic370194.html
However, I could not run that, either. The scareware would not let me run it even after I
renamed it explorer.exe.
I finally noticed that the fake Windows Security warning was running as a task in the bottom
task bar, and I right-clicked, and closed it. Then I was able to run setup_mbam.exe, and
got that scanner to run, and it found the junk programs in memory and on my hard disk, and
I guess we can consider this closed, and thanks for your advice.
