It could just be that windows is corrupted. I would back up your data and try reinstalling windows. Another thing to consider here is if its at all possible if you have gotten infected? There is a zero access rootkit out that will mess around with your internet connection. If you think you may be infected do this.
Please download and run
TDSSkiller
When the program opens, click on the start scan button.
TDSSKiller will now scan your computer for the TDSS infection. When the scan has finished it will display a result screen stating whether or not the infection was found on your computer. If it was found it will display a screen similar to the one below.
To remove the infection simply click on the Continue button and TDSSKiller will attempt to clean the infection.
When it has finished cleaning the infection you will see a report stating whether or not it was successful as shown below.
If the log says will be cured after reboot, please reboot the system by pressing the reboot now button.
After running there will be a log that will be located at the root of your c:\ drive labeled tdsskiller with a series of numbers after it. Please open the log and copy and paste it back here.
Please download
Malwarebytes' Anti-Malware from
here or
here and save it to your desktop.
- Double-click mbam-setup.exe and follow the prompts to install the program.
- At the end, be sure a checkmark is placed next to
- Update Malwarebytes' Anti-Malware
- and Launch Malwarebytes' Anti-Malware
- then click Finish.
- If an update is found, it will download and install the latest version. Please keep updating until it says you have the latest version.
- Once the program has loaded, select Perform quick scan, then click Scan.
- When the scan is complete, click OK, then Show Results to view the results.
- Be sure that everything is checked, and click Remove Selected.
- A log will be saved automatically which you can access by clicking on the Logs tab within Malwarebytes' Anti-Malware
If for some reason Malwarebytes will not install or run please download and run
Rkill.scr,
Rkill.exe, or
Rkill.com. If you are still having issues running rkill then try downloading these renamed versions of the same program.
EXPLORER.EXE
IEXPLORE.EXE
USERINIT.EXE
WINLOGON.EXE
But
DO NOT reboot the system and then try installing or running Malwarebytes. If Rkill (which is a black box) appears and then disappears right away or you get a message saying rkill is infected, keep trying to run rkill until it over powers the infection and temporarily kills it. Once a log appears on the screen, you can try running malwarebytes or downloading other programs.
