For about a week now, my computer has been very slow on start up in normal mode and will freeze constantly during use, the only remedy being to just leave the computer alone for a half hour before it unfreezes. I've updated and performed full scans using SUPERAntiSpyware along with Malewarebytes Anti-Malware several times (and ten minutes ago) without any dangerous files being detected.

I have windows 7 and I'm currently running in safe mode with networking, though it appears that I cannot install/uninstall programs?

Any help is much appreciated, if this is malware I would like to quickly fix it before my computer becomes unusable.

Hello

This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

FixNCR.reg

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.



Please download aswMBR ( 511KB ) to your desktop.
  • Double click the aswMBR.exe icon to run it
  • Click the Scan button to start the scan
  • On completion of the scan, click the save log button, save it to your desktop and post it in your next reply.



Please download TDSSKiller.zip and and extract it.
  • Run TDSSKiller.exe.
  • Click on Change Parameters
  • Put a check in the box of Detect TDLFS file system
  • Click Start scan.
  • When it is finished the utility outputs a list of detected objects with description.
    The utility automatically selects an action (Cure or Delete) for malicious objects.
    The utility prompts the user to select an action to apply to suspicious objects (Skip, by default). Let the options as it is and click Continue
  • Let reboot if needed and tell me if the tool needed a reboot.
  • Click on Report and post the contents of the text file that will open.

    Note: By default, the utility outputs the log into system disk (it is usually the disk with installed operating system, C:\) root folder. The Log have a name like: TDSSKiller.Version_Date_Time_log.txt.

How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
