The potentially misleading prompts that your computer needs optimization are only half the problem with Onesafe Pc Cleaner “VIrus”. The other half are the potential changes that this app may make to your Registry. Normally, optimization tools like this one tend to delete redundant Registry keys in order to improve the performance of the PC. While this is unlikely to make any perceivable difference in the productivity of your computer, it’s not something harmful. However, certain issues may arise if the optimizer accidentally deletes a Registry key that your system actually needs. There are a lot of examples of users who have actually had this problem and we are here to tell you that it’s preferable if you don’t allow some already questionable software to tinker with your Registry Editor.
