I'm having large dificulties after avast moved 4 trojans into its virus
chest. I have used all freeware for trojan removal, including sophos
sav32cli with most recent ides for after avast procedure because things
are bad. Right now trojan remover is doing its last scan but seems taht
disc have been disinfected. I think trojans messed up the registry keys
and maybe some other things. In device manager there is WAN miniport with
exclamation mark which I don't need but it is unpossible to unninstal it.
Does someone have any advice?
As suggested by Malke and Ken Blake:
Reformatting of HDD is the preferred course of action!
"The only way to clean a compromised system is to flatten and rebuild.
Thatÿs right. If you have a system that has been completely compromised,
the only thing you can do is to flatten the system (reformat the system
disk) and rebuild it from scratch (re-install Windows and your
applications)..."

There are however a number of valid reasons where this may not be possible
or achievable. Not everybody is technically versed to do so or has an
experienced acquaintance who may be able to assist. There are many users
who reside in less developed environments where professional help just does
not exist or is very hard to come by. Therefore, a user may find the
procedures as per:

http://www.elephantboycomputers.com/page2.html#Reinstalling_Windows
too overwhelming and shy away from the perceived complexeties of
re-installing the OS.
The procedures as per:
http://www.claymania.com/removal-trojan-adware.html
(especially David's MULTI_AV Tool) have had helped solving malware issues
for uncountable users for many years; And is (IMO) the next best thing to
flatten and rebuild an operating system. It can keep you going until
experienced and/or professional is available for thorough examination
and/or reformatting of HDD.
