android sticky viruses and adwares

Hey guys.

I'm posting over there as there are developpers here and i think my problem is more about system level
stuff than user level.

on my TM1007 tablet i caught some kind of virus ( well i'd better say this virus caught my tablet :P ).
It's one of those things that hack the android browser forcing the homepage to open on www . gotoamazing . com
This is the visible part of the iceberg but i wonder wether this virus does or don't log keys, passes, and anything else.
I'm a former linux user and am really stunned a linux based OS like android is, is this weak and virus-open !!!!!!

ok let's go deeper in the issue.
of course i started with all the tuts showing how to get rid of viruses and adwares.... useless....
the only app that detected thingies is adwcleaner and it just does nothing but deleting the install package APK.
nevertheless, when the APK has spread it's poison over the system it's pretty useless.....

so, what i did:
-installed the few thingies for obtaining the root access
-installed a console... weeeeee best game ever on linuxes 8-D
-grepped for "gotoamazing" on root folder
and....
OMG !!!!! it's everywhere !!! :eek:
in browser cache
in browser conf
in browser database......

so the final question:
-does anyone know an app able to really search for viruses and clean the infected files instead of just and always triggering a popup sayin all is fine ?
-does anyone even know this 'gotoamazing' crap ? and fought it ? and in this case what was the solution ?

thanks a lot in advance for all you help and have a nice day !!!

regards.
