Hello again 2403graeme,
Tough malware issue, and will be running processes that will kill things that can disable or remove the malware. I have found with some of the newer rogue security softwares that right as the desktop appears on bootup there is a slim window of opportunity to get Task Manager to open (press Ctrl - Alt - Delete) before the malware blocking functions load. If you get Task Manager access you can click the Processes tab, and there hilight and End Process the malware files. Difficult to pinpoint what they would show as, though often they use names similar to the fake software name (av2009.exe perhaps for this one), or obviously random letter file names. See if you can work around these blockers and get some scans run to post info here.
To keep them from interfering with the repairs, be sure to temporarily disable all antivirus/anti-spyware softwares while these steps are being completed. This can usually be done through right clicking the software's Taskbar icons, or accessing each software through Start - Programs.
(random's system information tool) from here
to your desktop. Then click on the RSIT.exe
to open the RSIT display, and click the Continue
If necessary allow it to locate or download a copy of HijackThis as needed.
Once the scan completes a textbox will open - copy/paste those contents here for review please. The log can also be found at C:\rsit\log.txt.RSIT will also create a second log
, info.txt, which will be minimized to your taskbar. Post that here as well please (it will also be stored at C:\rsit\info.txt).
You can break logs into parts and use separate posts here when replying and posting the log files, if needed.
Also click here
and download the installer for Gmer to your desktop, then click that file to run Gmer.
Once the opening scan finishes, click on Scan
(before scanning, make sure all other running programs are closed and no other actions like a scheduled antivirus scan will occur while this scan completes. Also do not use your computer during the scan).
When completed, click on the Copy button and rightclick on your Desktop, choose "New" > Text document. Once the file is created, open it and rightclick again and choose Paste. Copy the information and post it here please.
