I've been landed with my in-laws computer to troubleshoot. They are just computer-savvy enough to get rid of the password-protected administrator account I set up, and set themselves up as administrators!

Anyway, the computer has been playing up, failing to reboot properly, so I took a quick look.

(I've just added this bit, not trying to bump, just providing more details...
The situation is that if you reboot the computer, it starts to start up, gets so far, then bluescreens and reboots again. You then get the usual Safe mode option of starting. I booted in safe mode and it still bluescreened and restarted. If you try to restart in normal mode, same again, it basically sticks in a loop. However, if you switch off the pc for 10 secs, and switch on again, it boots up fine in normal mode.)

After reaming out dad-in-law about setting himself up as system admin, I poked around. In the windows security log there are several errors relating to corrupted files having bad hashes, mostly these files are BitDefender files (particularly bdselfpr.sys and bdfsfltr.sys), but also a windows system file called mdc8021x.sys (I have copies of the corrupt files and they scan clean with BitDefender on my PC.) I also installed and ran SuperAntiSpyware, and straight away a log entry showed up for a corrupted SASENUM.SYS. All points to the possibility of an embedded nasty in my book.

I've also run diagnostic tests to verify no hardware issues.

So anyway, ran HijackThis, and the log is attached.

I apologize for the very long delay. We have a huge backlog of HijackThis Logs to handle and it has been taking us greater time than normal to get caught up. If you are still having a problem, and want us to analyze your information, please post a brand new hijackthis log. If we do not hear back from you within a couple of days we will need to close your topic.

When posting your logs please post them directly into the reply. Do not attach them.

Also make sure you have already followed the steps outlined below:

Preparation Guide For Use Before Posting A Hijackthis Log

Thank you for your patience.
