Problems already fixed are displayed again during a new review

After the TuneUp Registry Cleaner or 1-Click Maintenance checks the registry database, problems may be displayed that are then fixed by TuneUp Utilities.

Immediately afterward, it is possible that some programs including security programs, antivirus programs and firewalls in particular may find such a change and revert to the "old" state virtually on their own in an effort to protect the system.

In this case, these entries appear again and it looks like TuneUp Utilities never deleted them.
You can ignore the display of such entries during future reviews. To do this, run "Clean Registry" under "Optimize". Open the group of displayed errors and mark the appropriate errors. With a right-click, a context menu opens where you can select "Ignore Problem."
