Re: Purpose of "UserAssist" registry keys?



Sammy,

HKEY_CLASSES_ROOT\CLSID\{5E6AB780-7743-11CF-A12B-00AA004AE837}
(Default)
REG_SZ
Microsoft Internet Toolbar

HKEY_CLASSES_ROOT\CLSID\{75048700-EF1F-11D0-9888-006097DEACF9}
(Default)
REG_SZ
ActiveDesktop

Deleting the entries should certainly be alright. As with all MRU keys they
will just fill up again. Some programmer at MS must've had too much time on
their hands. The entries in those two keys seem to be encrypted using
ROT13.

ROT13 shifts letters forward thirteen spaces in the alphabet. (a becomes n,
etc.) ROT13 ("ROTate by 13 places", sometimes hyphenated ROT-13, or
lowercase rot13) is a simple Caesar cipher. In cryptography, a Caesar
cipher, also known as a Caesar shift cipher or shift cipher, is one of the
simplest and most well-known classical encryption techniques. The method is
named after Julius Caesar, who used it to communicate with his generals.

Mine were cleaned out yesterday. This morning
....UserAssist\{5E6AB780-7743-11CF-A12B-00AA004AE837}\Count
had four entries.
....UserAssist\{75048700-EF1F-11D0-9888-006097DEACF9}\Count
had thirteen entries.

One entry in ...UserAssist\{75048700-EF1F-11D0-9888-006097DEACF9}\Count\
HRZR_EHACNGU:P:\JVAQBJF\Flfgrz32\JFpevcg.rkr

Just for fun I decoded it, using my Captain Midnight Secret Decoder Ring.
;-)

UEME_RUNPATH:C:\WINDOWS\System32\WScript.exe

Maybe I have too much time on my hands. :-) Time to go to work.

Of course after I decoded that one entry I found this site...
