What is Pegasun System Utilities?

Pegasun System Utilities says that it will maximize your PC performance among many other things

Pegasun System UtilitiesPegasun System Utilities may perform unwanted tasks in the background

Pegasun System Utilities is a system optimizer tool that claims to be able to do a lot of things completely for free, or for a very low price. A few of them include – maintenance, junk file elimination, performance boosts, heat minimizing. Programs that claim to be computer maintenance tools often end up being PUPs (potentially unwanted programs)[1] that perform various tasks in the background that they should not.

Often such program developers claim that you need an optimizer to “maximize the life expectancy” of your device. That is a bold claim. The reality is, there is little such programs can do, and most of the things they claim are not necessary or even advised against by IT experts. One of such claims is that you need to maintain the registry of your system regularly, when in fact, you should not mess with it, let alone give permission for a third-party program to do so.

Many people cannot imagine their daily routine without a computer utility such as this. Seeing the progress bar go up, the percentage increase, and then the green color lighting up the screen, saying that your system is now optimized and how much junk it got rid of is very satisfying and addicting. That does not make it real.

What is more, this system tool is not only distributed through the official site, but also through many questionable freeware[2] distribution pages. And we write about those all the time on our website. Most of the time they include additional programs to make their activities worthwhile. It is also not a good sign if an application is spread on many different pages. It indicated that the developers do not really care about user privacy or security.

NAME Pegasun System Utilities
TYPE Registry fixer; system optimizer; potentially unwanted program
SYMPTOMS The program appears running on the machine, causing the usage of extra CPU power. Additional browsing-related processes can be associated with the app, like redirects and pop-up ads
DISTRIBUTION Shady websites, deceptive and misleading advertisements, bundled software
DANGERS Users can experience performance issues while using their PC. Your privacy is also in danger since usually PUPs can track your activity
ELIMINATION Anti-malware tools can be helpful in fully eliminating PUPs, so run a system scan and remove the intruder
FURTHER STEPS Use a maintenance tool FortectIntego to repair any damage left and optimize the machine

A closer look into the claims of system tool developers

As we mentioned before, almost all registry utility vendors say that you need to clean your registry[3] regularly. Let's look at the facts. There is no statistical evidence of the performance improvements. Every vendor has different criteria for defining a “bad entry.” Some utilities do not even make backups of the registry before making changes to it. The removal of registry entries can make malware removal difficult, and if the program would mess something up, the fix would not be easy.

If you would happen to have your registry entries messed up, it could cause various system errors and missing file pop-ups. A registry cleaning program could help, but other factors are often the main culprit. If an important component of your registry is compromised, a registry utility would be completely useless.

User privacy and security concerns

Another reason you should be skeptical about such programs and avoid them is that the promotional sites always boast about how it protects their users' privacy. This is what Pegasun System Utilities say about their privacy features:

Keeps your privacy safe by blocking sharing data to third-party services, such as ad network, tracking cookies, data collection. It also cleans your sensitive information, so it does not fall into the wrong hands.

What you should consider is that in itself it is a third-party program that collects various information about you, like your IP address and browsing activity. The authors say that they will protect your data so it would not fall into the wrong hands. The weird thing is, that the program that they let you download was flagged by 7 security vendors as malicious on VirusTotal.

It is up to you to decide if you trust this system optimization tool or not and if it is actually beneficial. We strongly suggest not using it, as there are almost no customer reviews that you can find on the Internet about it, and the claims are very bold. Feels like the creators have written every possible thing to lure you in.

Microsoft even has a support policy[4] for the use of registry cleaning utilities and it says:

Microsoft does not support the use of registry cleaners. Some programs available for free on the internet might contain spyware, adware, or viruses. If you decide to install a registry cleaning utility, be sure to research the product and only download and install programs from publishers that you trust.

Start the elimination process by shutting down suspicious processes

You can also go to Windows Task Manager to check what processes are running in the background and see if there is anything suspicious.

Shut down unwanted processes

  1. Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
  2. Click on More details.
    Open task manager
  3. Scroll down to Background processes section, and look for anything suspicious.
  4. Right-click and select Open file location.
    Open file location
  5. Go back to the process, right-click and pick End Task.
    End task
  6. Delete the contents of the malicious folder.

Check program Startup

  1. Press Ctrl + Shift + Esc on your keyboard to open Windows Task Manager.
  2. Go to Startup tab.
  3. Right-click on the suspicious program and pick Disable.

Ways you can remove malicious applications

Manual removal of PUPs may not always work, as you can uninstall the program itself, but leave some related files behind. That is why we suggest using professional security tools like SpyHunter 5Combo Cleaner or Malwarebytes in this instance. These anti-malware tools will completely eliminate the application with all of its files and entries. If you still want to do this yourself, you can follow the guide below:

Instructions for Windows 10/8 machines:

  1. Enter Control Panel into Windows search box and hit Enter or click on the search result.
  2. Under Programs, select Uninstall a program.Uninstall from Windows 1
  3. From the list, find the entry of the suspicious program.
  4. Right-click on the application and select Uninstall.
  5. If User Account Control shows up, click Yes.
  6. Wait till uninstallation process is complete and click OK.Uninstall from Windows 2

If you are Windows 7/XP user, proceed with the following instructions:

  1. Click on Windows Start > Control Panel located on the right pane (if you are Windows XP user, click on Add/Remove Programs).
  2. In Control Panel, select Programs > Uninstall a program.Uninstall from Windows 7/XP
  3. Pick the unwanted application by clicking on it once.
  4. At the top, click Uninstall/Change.
  5. In the confirmation prompt, pick Yes.
  6. Click OK once the removal process is finished.

Repair the damaged operating system

Performance, stability, and usability issues, to the point where a full Windows reinstall is required, are nothing unusual after a virus infection. These types of intruders can alter the Windows registry database, damage vital bootup, and other sections, delete or corrupt DLL files, etc. Once a system file is damaged, antivirus software cannot fix it.

Manual troubleshooting of such damage is also very complicated and can take a long time. This is why FortectIntego was developed. It can fix a lot of the damage caused by an infection like this. Blue Screen errors, freezes, registry errors, damaged DLLs, etc., can make your computer completely unusable. By using this actually useful maintenance tool, not a Pegasun System Utilities PUP, you could prevent yourself from having to reinstall WIndows completely.

  • If User Account Control (UAC) shows up, select Yes
  • Press Install and wait till the program finishes the installation process

How to prevent from getting system tools

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
