How do I remove ProPC Cleaner? When I hit "uninstall" it overrides the normal process.

Hi Keyboards
 
Welcome to the Community Forums.
 
You sound like a knowledgeable person based on what you have described so the best thing is for me to point you at what we normally respond to such questions, which is that....
 
WSA does detect and remove many PUA's, and more are being added, but WSA does not detect all of them. And some are intentionally difficult to locate and remove are.
 
Please see THIS LINK for more information regarding Webroot's stance on these annoying programs.
 
For those that are not detected by WSA, please see this KB Article. It has some easy to follow directions on locating and removing PUA's, some or all of which you may have tried already...but worth a read in case there is something in there that you have not yet tried.
 
Finally, if all of that fails then may also want to submit a Support Ticket, especially if you cannot remove it easily from the directions in the KB Article, or where you have tried yourself to remove the nasty but it keeps on returning.  Webroot Support will help you get these annoying 'crapware' off your computer at no extra charge, and the additional examples may help to better automatic removal of that particular PUA for all users in the future.
 
Finally, and to help in the future to make sure that your WSA is checking for PUA's with the best proficiently, it sometimes helps to reset the PUA detection within WSA's settings. For PUA's that had previously been scanned and determined to be OK, but have since been added to detection/removal, you may want to complete the following steps:
 

• Open Webroot SecureAnywhere
• Click on ‘Advanced Settings’ from the top right
• Select ‘Scan Settings’ from the left side
• Unselect the option “Detect Potentially Unwanted Applications”
• Click on the Save button (you may have to enter in a CAPTCHA)
• Reselect the option to “Detect Potentially Unwanted Applications”
• Click on the Save button
• Run another scan with Webroot and remove any items that get detected.

To help avoid PUA's in the future, remember to read all of the information when installing or updating software (Adobe downloads often have those "extra special offers" attached... PUA'S!: often the PUA included will be mentioned, and you can opt out of installing it.  Those check boxes you see? Usually only one of them is for the User Agreement of the software you want, the others are for the junk you don't.
 
As I said the above is our standard reply from this type of enquiry so I hope that some of it has been or will be of use to you in your quest to be rid of this nasty...but in the final analysis you may need to Open that aforementioned Support Ticket and get the professional of the Support Team to deal with it for you.
 
Let us know how you get on.
