Hello, that is an IRC/Bot rootkit called W32/Virut.h.... http://vil.nai.com/vil/content/v_143034.htm
A backdoor Trojan can allow an attacker to
gain control of the system, log keystrokes, steal passwords, access personal
data, send malevolent outgoing traffic, and close the security warning
messages displayed by some anti-virus and security programs.
I would advise you to disconnect this PC from the Internet, and then go to
a known clean computer and change any passwords or security information held
on the infected computer. In particular, check whatever relates to online
banking financial transactions, shopping, credit cards, or sensitive
personal information. It is also wise to contact your financial institutions
to apprise them of your situation.
We will do our best to clean the computer of any infections seen on the log.
However, because of the nature of this Trojan, I cannot offer a total
guarantee that there are no remnants left in the system, or that the
computer will be trustworthy.
Many security experts believe that once infected with this type of Trojan,
the best course of action is to reformat and reinstall the Operating System.
Making this decision is based on what the computer is used for, and what
information can be accessed from it.
Knowing the above, let us know if you wish to proceed.
Did you do a low Level format,prior to reinstall? Are there any Flash,USB etc... driives being reconnected to the PC that may have had contact and are reinfecting it.
You can try the AVG Virut Remover
. Follow the instructions exactly as specified and pay close attention to the instructions including the note on administrator rights
. If that does not work, there may be no recovery
from this infection. The only thing you can do then is reformat and reinstall Windows. Virut/Virtob
is contracted and spread by visiting remote, crack and keygen sites
. Those who attempt to get software for free may end up with a computer system so badly damaged that recovery is not possible and a Repair Install will NOT help
! Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Starting over, reformatting the drive and performing a clean install removes everything.
Use the free version of Killdisk
