ntmarta.dll is a Windows Vista system file.
Try running MalwareBytes:
http://www.malwarebytes.org/
Download the free version, open it and then go to the Update tab
and check for the latest definition file.

Hello Daniel,

SUPERAntiSpyware is worth a try as well.

<http://www.superantispyware.com/>

After the software is updated, it is suggested scanning the system in Safe
Mode.

SUPERAntiSpyware just put up a Online Safe Scan at
<http://www.superantispyware.com/onlinescan.html>
if you cannot install and/or run the current SUPERAntiSpyware product due to
an infection.
-=-

There is not one software that will detect / remove / block all possible
virus / malware.

There is no "permanent" solution besides running spyware / virus
protection.

You may also want to install ThreatFire (also FREE).
<http://www.threatfire.com/> This is a good program that compliments your
existing antivirus program.


Safe Hex:
