PC Speed Maximizer Screenshot 1PC Speed Maximizer is a rogue system optimizer and registry cleaner that claims to improve the performance of your computer by removing junk files and unneeded data, but actually detects fake system problems. Trying to use PC Speed Maximizer to remove any of these imaginary issues only will redirect you to a purchase form for PC Speed Maximizer's registration. PC Speed Maximizer also has been promoted through multiple malicious websites and through the fake online scanner XP Micro Antivirus Online Scan. Scamware products like PC Speed Maximizer never should be bought, and although SpywareRemove.com malware experts haven't seen evidence of PC Speed Maximizer engaging in other attacks of a more serious nature than its fake system scans, they, nonetheless, suggest removing PC Speed Maximizer with any legitimate anti-malware scanner.

Why PC Speed Maximizer's Only in It for Maximum Profitability

PC Speed Maximizer uses a hoax that's common to many families of fake anti-malware and system cleaner programs, such as FakeSysdef, FakeRean and WinWebSec, by pretending to find problems with your PC without having any real capabilities for detecting them. As a simulated scanner, PC Speed Maximizer only is able to create fake scan results and pop-ups, which PC Speed Maximizer hopes will be enough to convince you to spend money on 'cleaning' your PC.

PC Speed Maximizer is associated with the sites speedupyourpc.com and Pcspeedplus.com/scan, both of which promote PC Speed Maximizer and an equally-fake online scanner named XP Micro Antivirus Online Scan. The latter often will launch automatically and initiate a fake scan that proceeds to encourage you to install PC Speed Maximizer when you try to remove any detected threats, essentially tricking victims into infecting their own computers. SpywareRemove.com malware researchers warn that, while PC Speed Maximizer uses a standard scamware interface, XP Micro Antivirus Online Scan is designed to look like a Windows Explorer add-on and may be launched through advertising rings and equally-untrustworthy sources.

Putting the Brakes on PC Speed Maximizer's Race to Your Money

As a fake system scanner that's incapable of improving your PC's performance or implementing any of the features PC Speed Maximizer claims to have, PC Speed Maximizer should not be purchased. If you've spent money on PC Speed Maximizer already, malware experts recommend contacting your bank or credit company to get any charges canceled. Protecting your computer from sites and online PC threats related to PC Speed Maximizer, such as XP Micro Antivirus Online Scan, can be accomplished through browser-specific security techniques, such as the often-recommended disabling of JavaScript (which is a benign but commonly-exploited program).

Lastly, SpywareRemove.com malware research team also urges you to remove PC Speed Maximizer from your computer whenever appropriate. PC Speed Maximizer doesn't have any history of causing long-term damage to the PCs that are compromised by PC Speed Maximizer, but the presence of scamware like PC Speed Maximizer always should be considered a drawback for your PC's performance and security. Most anti-malware products are well-equipped to deal with basic fake system cleaners like PC Speed Maximizer.
