psd file locked

[DeviantEye]

I installed the Photoshop Beta to try out the remove tool. After UNISTALLING the photoshop beta via the Creative Cloud Desktop app, I am now unable to open psd files getting the following error message

Could not open "xxx.psd" because the file is locked, you do not have the necessary access permissions, or another program is using the file. Use the 'Properties' command in the Windows Explorer to unlock the file.

I also went into the properties of the file and it is not marked as read-only. This happens with every psd file that I try to open.

How do I fix this issue and unlock the psd files?

Thanks in advance for helping.

It sounds like the same issue from this thread:

• Cant save a file "because the file is locked, you do not have access permissions" 

The issue was the antivirus Avast. Uninstalling that fixed it.
