Had to detect this one myself!

[richup.exe]

MS Antispyware couldn't detect this one and it was
driving me nuts. every time I searched anything on Yahoo
with IE I got about 3-4 yahoo.store pop ups. anyhow after
scanning using SO MANY Checkers I checked through my
registry and startups myself only to find RICHUP.EXE
erased that SOB and I'm sailing smooth again.

MS CLEAN THIS SUCKER!!!

 

[Bill Sanderson]

I know that in the heat of battle this is hard to remember, but submitting a
Tools, Suspected Spyware report from an infected machine that Microsoft
Antispyware can't clean will help insure that it may be able to clean it
eventually......

The other thing to consider doing if you can lay hands on the executable, is
submitting it to antivirus vendors via:

http://www.virustotal.com
http://virusscan.jotti.org

This may give you a name to attach to the critter, and it may also show you
that other antivirus vendors are more on-the-ball than your own.
