My Windows 10 Pro x64 system has been slow and erratic lately. When I looked into the Events window, I see that there are about 90 errors every time I boot it up. Some on them are related to Windows' inability to verify digital signatures. Am I infected? How can I clear this up? Below is the text of one such error.


Thanks in advance for your help.

I would be surprised if you looked in the Event Viewer and didn't see any errors.  Not only does the Event Viewer usually contain errors the explanations for these errors are ambiguous at best.


Please run System File Checker.

The sfc /scannow command scans all protected system files and replaces corrupted and incorrect versions with correct Microsoft versions.

Important:  There will be a short message at the end of the scan informing you of the results.  If you receive the message "no integrity violations were found" you don't need to do anything else, no corrupt files were found.  You should watch the scan to see the results at the end of the scan.

This needs to be run using an Administrator account.  

You will need to open the Command Prompt to run the sfc /scannow.  The easiest way to do this is to press the Windows key and the X key.   A menu will open with the option Command Prompt (Admin), click on this.  This will open the Command Prompt.

Important:  Depending on which version of Windows 10 you are using the option in the menu for Command Prompt (Admin) may have been replaced with Windows PowerShell (Admin).  The command used here needs to be run from the Command Prompt (Admin).  

To switch the option back from Windows PowerShell (Admin) open the start menu, tap/click on Settings, then select Personalization, then Taskbar.

Under Taskbar you will see the option Replace Command Prompt with Windows PowerShell in the menu when I right-click the start button or press Window key + X key.  Move the switch so that Command Prompt (Amin) is on.

If you are prompted for an administrator password or for a confirmation, enter the password, or click Allow.

Copy and paste the command below in the Command Prompt, then press Enter.

sfc /scannow

This scan will take a while to run, please do not abort the scan as this can result in damage to the operating system.

If integrity issues are found in the scan please post the CBS log using the instructions below.

To find sfc /scannow log click/tap on File Explorer, select the drive which Windows is installed on (this usually is the C: drive), click/tap on Windows, then Logs, then CBS.  If there are more than one log you can identify the log you want by the date and time it was run.  

Copy and paste the log at the host website I've suggested below.

This log usually is very large, for this reason you should use a host website like Dropbox to post the log.  You can start a free 30 day trial.  Once you have loaded the log at Dropbox post a link to the website.


Please download AdwCleaner and install it.

When AdwCleaner opens click on Scan to start the scan.

Once the search is complete a list of the pending items will be displayed.  If you see any which you do not want removed, remove the check mark next to it.

If there are no malicious programs are found you will receive a message informing you of this.  
Click on Clean to remove the selected items.  If you have any questions about any items in the list please copy and paste the list in your topic so we can review it.  
You will receive a message telling you that all programs will be closed so that the infections can be removed.  Click on OK.  The computer will be restarted to complete the cleaning process.
When the cleaning process is complete a log of what was removed will be presented.  Please copy and the paste this log in your topic.
