How to uninstall Pegasun System Utilities from the operating system?

Also Known As: Pegasun System Utilities potentially unwanted application
Damage level: Medium

What is Pegasun System Utilities?

Pegasun System Utilities is a multifunction tool for cleaning, securing, and improving the performance of operating systems. However, due to the dubious methods used to distribute this piece of software, it is classified as a PUA (Potentially Unwanted Application). It is noteworthy that apps within this classification often have undesirable/harmful abilities and/or are bundled with such software.

Pegasun System Utilities unwanted application

Potentially unwanted application overview

Legitimate products can be distributed using questionable methods, yet such techniques are more commonly used to proliferate untrustworthy software. Furthermore, dubious apps can be promoted in bundles, often with genuine software at the forefront to increase the impression of legitimacy.

PUAs appear legitimate and offer "handy" functionalities. However, these features seldom work as advertised, and in most cases - they do not work at all. Fake anti-viruses are prime examples of this type; they require activation (purchase) to perform the functions, yet after activation - remain nonoperational.

What is more, unwanted apps can have harmful abilities, e.g., force-opening unreliable and malicious webpages, running intrusive advertisement campaigns (adware), modifying browsers to promote fake search engines (browser hijackers), and tracking data.

It is noteworthy that many PUAs have data tracking abilities. Targeted information includes (but is not limited to) - browsing and search engine histories, IP addresses, personally identifiable details, and finance-related data. The collected data is monetized by being shared with and/or sold to third-parties.

In summary, the presence of unwanted software on devices can lead to system infections, serious privacy issues, financial losses, and identity theft.

Potentially unwanted application examples

Win 10 TweakerPC Cleaner PerfectPC AcceleratorFix PC, and Telamon Cleaner are some examples of apps similar to Pegasun System Utilities.

This software usually looks useful and harmless. PUAs can have various disguises and promise a wide range of features, like system cleaning/optimization or easy access to specific online content. Regardless of how appealing these functionalities may sound - they are rarely operational.

Furthermore, PUAs tend to have dubious and even dangerous functions. Therefore, it is strongly advised to research software and download it only from official/verified sources.

How did potentially unwanted applications install on my computer?

Select PUAs (e.g., Pegasun System Utilities) have "official" promotional/download pages. However, they are most commonly spread by using the "bundling" marketing technique - packing regular programs with various additions. By rushing through downloads/installations (e.g., ignoring terms, skipping steps, etc.) - users risk allowing bundled content into their devices.

Intrusive advertisements are capable of infiltrating PUAs into systems as well. Once clicked on, the ads can execute scripts to make stealthy downloads/installations.

How to avoid installation of potentially unwanted applications?

It is recommended to always use official and trustworthy download channels. Dubious sources, e.g., Peer-to-Peer sharing networks, unofficial and free file-hosting sites, etc. - can offer bundled and hazardous content.

When downloading/installing, it is important to read terms, explore available options, use the "Custom/Advanced" settings, and opt-out from all supplements. Intrusive adverts appear legitimate, yet they redirect to highly questionable websites (e.g., pornography, adult-dating, gambling, etc.).

Should users experience ads and/or redirects of this kind, they must inspect their devices and immediately remove all suspicious applications and browser extensions/plug-ins detected. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
