Windows 7 - computer has been weird

Hi, kamikazikyle.

The normal location for rundll32.exe is System32, not AppData. If you have not done as already suggested by gregrocker, I would like to see a Malwarebytes' Anti-Malware log. First, however, please do the followng:

Download TFC by Old Timer from here (direct download): http://www.itxassociates.com/OT-Tools/TFC.exe

• First, save any files as TFC will close ALL open programs including your browser!
• Double-click on TFC.exe to run it. If you are using Vista/Windows 7 right-click on the file and choose Run As Administrator.
• Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
• Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

Next, please scan with MBAM:

• Launch Malwarebytes' Anti-Malware then click the Update tab and "Check for Updates
• Once the update has been installed and the program has loaded, select [b]Quick scan
• When the scan is complete, click OK, then Show Results to view the results.
• Be sure that everything is checked, EXCEPT items in System Restore as shown in this sample:
  
• Click Remove Selected.
• When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. (See the Note below)
• The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
• Please post contents of that file in your next reply.

** Note **

If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately.
