Potential trojan (fjhdyfhsn.bat) infection?
Hi: My sister may have picked up a trojan on her computer (fjhdyfhsn.bat) and I'm looking for some help to determine if it's still onboard. It created a desktop icon when it installed, and she unwittingly opened it. According to her, upon opening of the file the computer "went nuts"; from what I could glean from her description, a window popped up and registry values careened across it. I immediately had her scan her computer and then attempt to restore it to an earlier timepoint just in case it was a basic trojan/virus. I was able to look at the system myself the other evening, but cannot tell if it is still infected or not and am looking for additional help in doing so. I scanned the computer with Defender, Malwarebytes and Spybot (all installed previous to the infection), but none of the programs detected anything amiss. When connected to the internet there are no redirects to any unusual sites, but when I went to the homepage of a secured banking site I saw the Defender icon turn from green to orange and indicate that the computer was potentially unprotected. I'm not that familiar with the intracacies of Vista (which is her OS), but I know that Defender doesn't exhibit the same error activity with either XP or Windows 7, which makes me suspicious that her computer has some hidden infection still associated. Shown below are the Malwarebytes anti-malware scan (which detected nothing) and a DDS/GMER log. I personally don't see anything amiss in the logs, but I also am not a computer expert. 2009-02-20 20:35:12 8192 --sha-w- c:\windows\users\default\NTUSER.DAT ============= FINISH: 18:52:57.28 ===============
