Possible bootkit problems

Gazray4699 · September 28, 2011

Hello there,

My computer was recently infected with a virus from a pop-up and such a virus was immediately deleted by my antivirus - but several viruses managed to slip through somehow, possibly due to bootkit activity. When my antivirus requested a reboot to finish clean-up of the original virus, it shut down and then never managed to boot properly. It presented the blue-screen of death with the error message that an attempt was made to write to read-only memory. Eventually deciding to wipe the disk and reinstall Windows, the system seemed to work fine with no infection - even after linking the infected drive to another hard drive though before the wipe, it still only detected two infections which were eliminated but the OS still presented the BSoD. Eventually I decided to upgrade my system and obtained a new motherboard - the BioStar A780L - and also a new processor - an AMD Athlon II X2 Dual Core running at 3.2 Ghz (Upgraded from 2.61Ghz AMD Athlon 64 X2 Dual Core). I also added a 500GB SATAII hard drive as a backup drive. The computer now operates well and fast but when booting, it is incredibly slow despite a mostly empty OS drive. I have performed a Defrag and Disk Cleanup - however at the advice of a friend, I scanned using TDSSKiller for rootkits and was informed my BIOS.sys driver was suspicious because it was unsigned. I then performed scans using the advice of the "I'm infected" post and I have included the logs from them. Any help would be appreciated in confirming if the system is clean or not.

Thanks in advance.

P.S The new SATA drive hasn't been scanned, only the main directory has. For the two infections in the MalwareBytes log, I'm aware of them and think they're harmless. Feel free to contradict me though.

Do you want all of the scans and logs again? The thing is, the pinned post at the top told me to attach those logs.

My system is still running fairly slow despite the upgrades, though I recently discovered the frequency of my CPU is being limited for some reason to 800Mhz or 1.9 Ghz - still unsure why, though I supsect a feature in the BIOS is to blame. Toggling said feature did nothing either.

Boot-up is quick when loading the OS but start-up is incredibly slow despite being such a clean, freshly installed system. I'm capable of doing more than before when it starts up but it's still a little unusual.

Addition of a graphics card has also resulted in POST and BIOS graphical... messes. Screens are out of resolution and colour depth is appalling with half the screen off my monitor. That may not be related to an infection however.

As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal.

Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt using Copy / Paste in your next reply.

1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.

2. ComboFix may reset a number of Internet Explorer's settings, including making I-E the default browser.

3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you -- please tell your helper.

4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

Give it atleast 20-30 minutes to finish if needed.

Please do not attach the scan results from Combofx. Use copy/paste.

Also please describe how your computer behaves at the moment.

My computer still takes a while to load during start-up and my processor is being limited to only certain amounts of mhz/ghz when none of my motherboard's features that do such a thing are enabled. Apart from that, nothing really that noticeable. What concerned me was when the infection occured, only two viruses were found and removed and the OS on the hard drive before I wiped it still blue-screened upon the Windows log-on screen. This suggested to me that the Windows Log-on files were infected. I'm looking to confirm whether or not the infection has lasted through a complete format and reinstallation of Windows.
