Hi there.
I registered because I'm having a very strange problem. or quite a lot of them.
First symptom was that Flash videoes could not be played. It said the addon crashed. In both Firefox and Explorer. A reboot fixed it. But then it would return. When this happened, the sound went away on the whole computer as well. No sound on anything. Yet the sound card reported to be working correctly in hardware management.
Then after a while, explorer started crashing when I right click. Normal illegal operation dialog. The weird thing was that it said explorer.EXE. Not explorer.exe. This was the first time it crashed. Subsequent crashes reported all lower case letters.
This made me think I had a virus, so I installed Spybot Search and Destroy. ( I already had/have fully updated Avast! antivirus installed).
But it did not find anything.
Later, I have also had some strange reports of files not being correctly written. So I assumed it could be a hard drive problem. I really do not want to run a complete disk scan with sectors and all, since I have 1,5Tb diskspace. But a normal scan only came back with some incorrect space values. (don't remember the exact text) Anyway. All errors was fixed.
So now I ran HiJackThis. I don't see anything strange in the start of the log, but the last few lines report important files to be missing?
I hope someone more experienced with the program, or have had similar issues, could give me a hand:
Since there was a text limit (even with /code), here is the hijackthis log file:
