wow a persistent one are you sure rainbow nothing is wrong with rainbow...
because AboutBuster should remove even the very hidden application
all of the spyware i suggest you is to prevent they come but except spybot could
not remove already installed spyware...
also have you tried to run Ad-aware and spybot in safemode? as the procedure i've
given? the procedure need to be run from the first to the end... and in your case
need to run one more tool.. AboutBuster
I almost believe this item already back in the system
R3 - URLSearchHook: (no name) - {C7EDAB2E-D7F9-11D8-BA48-C79B0C409D70} - (no file)
also don't forget every removal operation always need clean all temp, temporary internet
files, recycle bin and turn off system restore before
