C:/Searchpage ,
step one download lavasoft adaware ,
step two download Hijack this place it in its own folder
step 3 goto C:/windows/system 32 and delete Mshelper.dll and then rename mtwirl.dll to Mtwirl.bogus.
Then search for C:searchpage file and delete it .
restart computer, run Hijack this and change have it fix all occurences of C:searchpage .
run adaware and get rid of rest .
go back to C:/windows/system32 and delete mtwirl.bogus
walla and god bless , it took me two days to figure it out.
PS dont play with your registers that Mtwirl.dll is active and rewriting them every 15 seconds. SO until you rename it and reboot your stuck with it
 
I heard from a few people that have this and got rid of it also .
A variant that is not as nasty called about blank can be rid of the same way. The rouge .Dll file is AOH.dll just follow the same instructions as above and rename AOH.Dll to AOH.bogus
