PC Performer is a Registry scanner that pretends to clean Windows Registry errors to enhance the stability and speed of your computer. Since PC Performer also creates some noticeable system performance issues along with displaying misleading system information, malware experts recommend deleting PC Performer quickly and with a trusted anti-malware program. Installation methods for PC Performer are known for using bundles that install PC Performer along with unrelated applications, and avoiding download sites with poor reputations can protect you from a possible PC Performer infection.

PC Performer is another Registry scanner that makes unusual claims about being able to increase your PC's speed by removing Registry errors – an unlikely solution to any performance problems, at best. Rather than bothering to provide any real Registry-cleaning features, PC Performer detects large lists (up to several hundred) Registry errors whenever PC Performer scans your computer. PC Performer may deliberately cause system slowdowns, which could lead an uninformed PC user to believe that Registry problems really are giving them issues. However, all performance issues will decline once PC Performer is uninstalled.

PC Performer also may use alerts, and separate adware programs also have been known to promote PC Performer through a number of popup-based advertising attacks. Infection vectors that lead to contamination by PC Performer or related adware programs may arrive through suspicious file-downloading sites, such as sites oriented towards providing illegal programs or piracy-related utilities. However, other means of acquiring a PC Performer, such as a third-party advertisement, also should be taken into consideration.

Kicking PC Performer Off of Its Stage

Although PC Performer tries to claim the spotlight as a program that theoretically can help speed up your computer, it is often classified as a PUP. PC Performer and similar Registry cleaners always should be uninstalled as fast as possible to minimize any security issues that they may provoke. Anti-malware products also can be used to be certain of deleting PC Performer completely, especially if you suspect that other forms of threats also may have been installed through the same methods as those used by PC Performer.
