I know this might sound like a silly question, but I am particularly caution when trying new things on my PC. I am on a 20 day free trial with the Avast Internet Security service.
I have noticed a feature called: "Cleanup Premium" under the 'Performance' tab.
The contents it recommends to remove to improve the performance of my PC are: Junk Files, Redundant Apps, Inefficient System Settings and Obsolete Registry Entries.
My question is more about the Redundant Apps, Inefficient System Settings and Obsolete Registry Entries. Would deleting all of these things not harm my PC in any way?
I have posted screenshots of the Redundant Apps, Inefficient System Settings and Obsolete Registry Entries that Avast claims I should delete. Please look at these screenshots and tell me if its safe to go ahead with this because truth be told, my PC is quite slow:
