PC Accelerator is a doubtful Windows optimization tool that can display bogus scan results

PC Accelerator scan result

PC Accelerator is a Windows optimization utility developed by Software Marketing Ltd. It has an active download website, though it has recently been found spreading bundled with other freeware. Due to this founding and some questionable activities that it performs on the system, cybersecurity experts from[1] and other reputable security vendors included PC Accelerator to the list of potentially unwanted programs (PUPs).[2] 

Name PC Accelerator
Developer Software Marketing Ltd
Classification PUP
Danger level Low. It's more irritating and useless than dangerous
Distribution Software bundling
Distinctive features Regular system scans, pop-up alerts reporting multiple system's problems
Removal method The quickest way to eliminate the whole package of PC Accelerator is to run a scan with Reimage Reimage Cleaner Intego

PC Accelerator virus promises to address Windows errors, eliminate junk files, protect the system from crashes, update drivers automatically, and ensure steady performance. The whole pack of functions is not free of charge. People can install only a free trial version for free, which will examine the system but won’t fix or improve anything. The full version of this app costs €39,95, which would be a proper sum of money for a reliable optimization program. However, PC Accelerator’s reliability is highly questionable.

The increasing number of threads where people complain about its performance and ask for help to remove PC Accelerator from Windows 10 and other OS versions prompted experts to test the tool. It has been found that this optimizer performs its tasks as scareware.[3] 

If you are not familiar with the term, scareware is a rogue tool, which seeks to trick its users into believing that the system needs serious maintenance and the urge to purchase a license of a tool. PC Accelerator virus is that kind of app. As soon as its free trial version is installed, it launches its scanner and provides a report. Typically, it lists hundreds or even thousands of files, registry entries, and app as problematic and indicates numerous errors.

Keep in mind that most of the content indicated in the report are the names of randomly chosen system’s files. That’s a catch used to foist paid version of the optimizer. It will not improve the system in a significant way. However, it will stop the regular system’s scanners and exaggerated scan results.

Even if you did not install the PC Accelerator purposely, but it started scanning the system out of nowhere, it’s a clear sign that you have recently installed a freeware bundle. This dubious application is currently spreading like a “recommended attachment” or various free apps.

PC Accelerator PUP displays untrustworthy scan resultsPC Accelerator is a legitimate optimization utility that has been classified as PUP due to misleading distribution and questionable performance

Experts recommend people to remove PC Accelerator virus not because it’s malicious. Naming it a virus is not the right term to use because the tool cannot harm the system. All it can do is to take up free space on your PC and pretend to be optimizing the system.

It is possible to remove PC Accelerator in two ways. You can get rid of it manually by following the manual removal tutorial at the end of this article. However, a much easier way to eliminate PC Accelerator is to run a scan with anti-malware tool, and remove virus damage with Reimage Reimage Cleaner Intego.

PC optimizers distributed by Bundling are classified as PUPs

The main reason why legitimate apps fall for the international classification of PUPs is distribution via freeware. Attached as optional downloads and disguised under Quick or Basic installation options, unwanted apps manage to infiltrate the system without being noticed.

This doubtful optimization utility has been revealed spreading by bundling either. Once installed, it initiates the system’s scans and urges people to pay for the license. To prevent such and similar installers, you should be cautious when installing free apps. Here’s a couple of tips you should keep in mind:

  • Select freeware download source carefully;
  • Initiate research about a freeware before downloading it;
  • Select Advanced or Custom installation option;
  • Read Privacy Policy and License Terms carefully;
  • Check each window disclosed on the installation wizard;
  • Opt out of “recommended downloads” that are pre-checked by default.

A guide on how to remove PC Accelerator from Windows

PC Accelerator removal can be initiated in a standard way, i.e., via Control Panel. Usually, it provides an official uninstaller, so launching it should be enough to uninstall the PUP completely.

However, if it was installed by bundling, it might not be the only PUP installed on your PC in a stealthy manner. To check that and eliminate all unwanted programs and their components, we would recommend you to remove PC Accelerator with the help of anti-malware.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
