Here are the problem's symptoms -- this laptop is getting Popups about spyware. A Windows Security Center pop-up says that it is infected with TrojanDownloader.xs. It also has lost it's networking functionality, it's sound and some services, including the Cryptographic Service. Some Control panels seem to be altered, for example nothing shows in the Users control panel. The anti-spyware programs that I got to run from the list were not updatable, since the updates could not be applied.
Please take a look at this log and let me know what is the best way to handle these problems.
Thanks,David

Hello


Apologize for the delay in response we get overwhelmed at times but we are trying our best to keep up.
If you have since resolved the original problem you were having would appreciate you letting us know.

Thanks and again sorry for the delay.

I need to advise you of some nasty backdoor trojans

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.
