Details:

I am running Windows Vista 64bit Ultimate

I first notice something was wrong when my McAfee AV wasn't running real time scanning. It refused to start up so I tried a manual scan and McAfee would spit out an error. I thought maybe swithcing to another Anti-Virus such as Microsoft Security Essentials would run and pick it up. It did and named it as Sirefef.b and Sirefef.y It seems this virus is sensitive to MSE and would auto-reboot my computer within 1 minute of MSE being loaded, whether I was in safe mode or not. In order to get my system to stay on for longer than 1 minute, I used my Vista disk to access the repair tool/command prompt and manually deleted the MSE files. Since then I am able to stay on indefinantly, however the virus/trojen is still playing tricks with my browser. I have tried running Malware Bytes, It recognizes threats, claims they will be removed with a reboot and it doesn't. I tried running aswMBR with Avast update downloaded and I get an error "Initialize Error C0000001 - driver not loaded", however it does a scan and finds things but it will not fix anything. Fake Antivirus Removal from Trend Micro seems to help with the Fake AV windows I get, but it's not a permanent solution.

DDS.txt is attached but GMER.log is not as it's a 64bit OS.


Any help would be greatly appreciated.

Thank You,

Both programs ran as they were supposed to except during combofix's run, they claimed McAfee was still running, but I had it uninstalled. I couldn't find it so I continued anyways. Combofix found an infected system file.

Should I try and reinstall McAfee now or is there more steps to do? I am not doing anything on this system until I hear otherwise

I have updated my Java as recommended and I have installed McAfee and it is real-time scanning again.

I ran a quick scan and it came out clean.


Only 1 thing left is my desktop still has test mode in the four corner regardless of the background image.


Other than that it seems I'm in the clear
