Posted 20 September 2010 - 01:58 PM

I have a 1 month old install of W7 Home Premium 32bit with all latest updates including McAfee Total Protection fully updated.

Today I have very slow / erratic access to the internet on this computer only. This PC is connected to the internet via wired ethernet / router.

My other computers (running different OS's) are running fine with normal web access speeds through the same router.

With some sites I get no connection at all (e.g. security software sites, msft online event info) - they eventually timeout, but it seems I can eventually get a response from search engine enquiries and some other sites.

I have switched ethernet ports on the router with no effect.

I have run several full disk scans (using McAfee) with nothing significant detected (just a few adware cookies).

I have no error messages or warnings on reboot or login.

The event viewer does have a few errors / warnings e.g.

I'd appreciate your advice as to what action I should take next.

I have a Hijackthis log but will await further instructions before posting it.

Thanks!

I do not think it's infection myself,but let's get one more log.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.
Before you save it rename it to say zztoy.exe


alternate download link 1
alternate download link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

I also begining to suspect this problem is not malware related although I have no idea what's causing it apart from perhaps a badly aborted backup. I have tried a clean startup but still no joy.

Back to your instructions above - unfortunately the link your gave for the manual definition updates doesn't work. I had a look around on that site and couldn't find them either. I can't update MBAM on my w7 PC as internet access is so bad so I need to download seperately on a memory stick.

I didn't provide a manual link yet??

If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.
***
Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine..

Note: Mbam-rules.exe is not updated daily. Another way to get the most current database definitions if you're having problems updating through the program's interface or have already manually downloaded the latest definitions (mbam-rules.exe) shown on this page, is to do the following: Install MBAM on a clean computer, launch the program and update through MBAM's interface. Copy the definitions (rules.ref) to a USB stick or CD and transfer that file to the infected machine. Copy rules.ref to the location indicated for your operating system. If you cannot see the folder, then you may have to Reconfigure Windows to show it.
  • XP: C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware
  • Vista: C:\Documents and Settings\Users\All Users\Malwarebytes\Malwarebytes' Anti-Malware
If this won't work then We need a deeper look. Please go here.... Using the USB
Preparation Guide ,do steps 6 - 9.


Please go here....using the USB.
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
Skip Gmer.
Let me know if that went well.

Did I misunderstand this?...

[*]If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.


Here is the log, clean as a whistle...

However, strangely enough the problem has gone away - I have no idea why although at one point I did a clean reboot and I have uninstalled PowerDVD and a couple of other programs.

I still have VSS errors in my event log but that perhaps is another issue.
