SpeedMaxPC Screenshot 1SpeedMaxPC is a PUP system optimizer that's marketed at both SpeedMaxPC.com and HijackThis.com (the latter of which should not be confused with websites that sell the legitimate HijackThis program). SpeedMaxPC claims to have functions for cleaning your Registry and managing driver updates, but all SpeedMaxPC is capable of doing is deleting arbitrary files that, in many cases, are necessary for your operating system's stability. If you find SpeedMaxPC on your computer unintentionally, anti-malware programs should be used to remove SpeedMaxPC before SpeedMaxPC can harm your machine by deleting any critical files.

Why Trying to 'Max' Your PC May Result in the Opposite

Although SpeedMaxPC claims to have various functions that can speed up your PC, SpeedMaxPC actually doesn't have any benign functions whatsoever and can't optimize your PC or otherwise help its performance. All of SpeedMaxPC's real features focus on delivering scans and alerts with fraudulent system information. More disturbingly than that, in some cases, SpeedMaxPC detects real files as problematic and deletes them, which may, in some cases, cause your computer to become completely unbootable.

An Efficient Computer without the Counterproductive Helping Hand of SpeedMaxPC

Since SpeedMaxPC, far from being a system optimizer, is a meaningful danger to your computer that shouldn't be trusted to clean up or otherwise assist with your files in any way, malware researchers suggest deleting SpeedMaxPC as soon as possible after its installation. SpeedMaxPC may be downloaded through poorly-regulated freeware sites, other sites affiliated with scamware or malicious advertisements, and, in most – but not all – cases, requires your permission to be installed.

Making sure that SpeedMaxPC is removed completely usually mandates using a trustworthy anti-malware program, which can detect and delete all files and settings changes that are linked to SpeedMaxPC. Unlike some other forms of scamware, SpeedMaxPC hasn't been found to block such programs, but, if they're required, SpywareRemove.com malware experts can recommend other tactics, such as booting in Safe Mode prior to an anti-malware scan.
