PC Performer by Performersoft is presented by its publisher as registry cleaner software. In fact once installed it informs you that several issues were detected on your computer. When you try to fix these errors, PC Performer fixes them partially and states that you need to buy its full version to fix all the issues.

PC Performer can get inside the system in a bundle with other programs. Typically, it is distributed via freeware and shareware applications. That is why you should always choose a custom installation and uncheck unknown applications to avoid such unwanted guests.

As soon as it gets inside, PC Performer starts trying to convince its users that it is a real program that tries to prevent the danger. For that, it shows continuous pop-up ads and reports about various errors. You should ignore them because PC Performer is not capable to solve them.

Frequently PC Performer is classified as a PUP or potentially unwanted program because it displays fake alerts, fake scanning results, and pop-ups.


 
The Windows registry is a database which store information, including user preferences, settings and license information, about hardware and software installed on a user's computer. It contains huge amount of entries. Some of them may be outdated — maybe you’ve uninstalled a program and it left a key or two behind, or maybe a there’s a file extension with no associated application.

PC Performer finds such outdated entries and offers to remove them. Unfortunately, there is always a chance that this program may also remove some useful registry entries. In a best case scenario, PC Performer will remove a few hundred unnecessary entries and reduce the size of your registry by a few kilobytes only. That doesn't have big influence to performance of your computer. You should realize that registry is a very important part of your PC. There is no way to restore data from here once you delete something. And if you delete an incorrect component by mistake, it may damage your OS and make it inoperative. So if you are not confident enough with the registry we do not recommend to clean it manually or using such kind of software.
