PC Accelerator removal instructions
What is PC Accelerator?
Developers present PC Accelerator as a great tool to optimize and speed up your computer. Initially, this app may seem legitimate and useful, however, PC Accelerator is categorized as a potentially unwanted program (PUP). PC Accelerator often infiltrates systems without permission and provides no real value for regular users.
After running PC Accelerator and scanning the system, users are prompted with many 'issues' that must be resolved. Since the 'free version' of PC Accelerator is not capable of these functions, however, users are encouraged to purchase the 'full version'. This is a scam. The entire list of issues is false - your system is likely to be perfectly optimized and issue free. Furthermore, PC Accelerator provides no significant value. Criminals use this application to trick users into purchasing supposed full versions that are useless. Developers generate revenue by abusing users' trust. For these reasons, you should uninstall the PC Accelerator PUP and certainly do NOT pay for the full version. Note also how PC Accelerator is installed. As mentioned above, it is likely to infiltrate systems without permission. There is a high probability that it will install together with a number of other PUPs. In most cases, potentially unwanted programs do three things: 1) display intrusive advertisements [adware]; 2) modify web browser options [browser hijackers], and; 3) gather various information [typically, many types]. As with PC Accelerator, these apps are also useless. Therefore, we strongly recommend that you uninstall all PUPs as soon as possible.

PC Accelerator shares many similarities with Advanced PC Care, PCMax, System Keeper, and dozens of other potentially unwanted programs. In fact, all are virtually identical. By offering "useful features", PUPs attempt to give the impression of legitimacy, but are designed only to help developers generate revenue. Rather than enabling the functionality promised, potentially unwanted programs deliver intrusive advertisements (via the "Pay Per Click" [PPC] advertising model), promote rogue sites (unwanted redirects), gather sensitive data (information sales), and, in this case, promote in-app purchases. These programs pose a direct threat to your privacy and Internet browsing safety.
How did PC Accelerator install on my computer?
Potentially unwanted programs are often distributed using intrusive advertising and "bundling" methods. Intrusive advertisements redirect to malicious websites and run scripts that stealthily download and install malware or PUPs. "Bundling" is stealth installation of third party applications together with regular programs. Developers do not disclose these installations properly - they hide "bundled" apps within "Custom/Advanced" settings or other sections of the download/installation processes. Furthermore, many users click dubious links/ads and skip download/installation steps. This behavior often leads to inadvertent installation of potentially unwanted programs.
How to avoid installation of potentially unwanted applications?
The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. To prevent system infiltration by PUPs, be very cautious when downloading/installing software and browsing the Internet. Carefully analyze each step of the download/installation processes using the "Custom" or "Advanced" settings. Opt-out of all additionally-included programs and decline offers to download/install them. We also advise you to download your applications from official sources only, using direct download links. Third party downloaders/installers are often monetized using the "bundling" method, and thus, these tools should not be used. Be aware that intrusive ads usually seem legitimate, but redirect to gambling, adult dating, pornography, and other dubious websites. If you encounter these redirects, immediately remove all dubious applications and browser plug-ins.
