AdwCleaner comes with Tools: Quarantine Manager & HOSTS Anti-PUP/Adware.
When AdwCleaner is first run to clean adware, it will create a new folder located at C:\AdwCleaner. The AdwCleaner folder contains sub-folders for Backup and Quarantine. Each of these folders contain sub-folders of the exact location (full path) an entry was removed from. In the event you want to restore an item, simply run AdwCleaner again.
Click Quarantine manager.
A log file of what was removed will open in a new window.
Scroll through the list and find the entry you want to restore.
Place a check mark in the box next to the entry(s).
Click the Restore button.
