Win 7 64 bit Dell Optiplex 780. 4G RAM.

 

A few days ago the system went sideways and now I have very high (but fluctuating) CPU usage and memory usage.  Processes in Task Manager  are running wild and some are showing multiple instances where I wouldn't have expect them to be so. Using Chrome to make this post but IE repeatedly crashes and allowing the crash to search for a resolution to the problem does not produce results. Details have shown issues with various dll files. 

 

I've temporarily removed avast. Installed and run malwarebytes, adware, jrt, ccleaner. Did a scan disc. All these come back clean.

 

Thinking this is a windows issue but not sure where to start. 

 

Any thoughts?

 

Thanks,

Dawn

Hello chasingstillness

Please start with this program.
 

Download Malwarebytes Anti-Rootkit (A.K.A. MBAR) from HERE

  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • Click on the Cleanup button to remove any threats and reboot if prompted to do so.
  • Wait while the system shuts down and the cleanup process is performed.
  • Perform another scan with Malwarebytes Anti-Rootkit to verify that no threats remain.
  • If they do, then click Cleanup once more and repeat the process.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log.txt and system-log.txt

 

Thank You
