Uninstall the System Cleanup unwanted application

What is System Cleanup?

System Cleanup is software promoted as a system cleaner and optimizer. It is supposedly capable of scanning systems and removing "junk" and temporary files, and other unnecessary data.

This program has an official web page from which it can be downloaded free of charge (or users can purchase the "premium" version), however, System Cleanup can also be installed together with other software. This deceptive marketing method of packing regular programs with unwanted content is called "bundling".

Rushed download/installation processes also increase the risk of device infiltration. Due to its dubious mode of distribution, System Cleanup is classed as a PUA (Potentially Unwanted Application).

As System Cleanup is classed as a PUA, it is deemed untrustworthy and might also be a threat to the device and/or user safety. You are strongly advised against downloading/installing this application and other similar programs. Most PUAs require to be activated by making a purchase, however, they often do not work as advertised or are simply nonoperational.

Furthermore, download/install set-ups are used to proliferate System Cleanup and frequently contain more than one PUA (e.g. browser hijackers or adware). These unwanted applications have many harmful features. They generate redirects to sale-oriented, untrustworthy and even malicious web pages.

Additionally, using various tools, they enable third party graphical content to be displayed on any site and deliver intrusive ads campaigns (e.g. pop-ups, surveys, banners, coupons, etc.). These ads seriously diminish the browsing experience by limiting browsing performance and overlaying web page content.

They also generate redirects to rogue sites and can execute scripts to stealthily download/install PUAs. Unwanted applications have another dangerous capability: data tracking. By recording browsing activity (URLs visited, pages viewed, search engine history, etc.), they gather users' personal information (IP addresses, geolocations, and other private details).

This data is then shared with third parties (potentially, cyber criminals) seeking to misuse it to generate revenue. Therefore, PUAs can lead to system infiltration and infections, and severe privacy issues (including identity theft). To ensure device and user safety, remove all suspicious applications and browser extensions/plug-ins immediately.

All PUAs tend to be quite similar. They are designed to seem legitimate and offer a broad array of "useful" and "beneficial" features. Full PC Care 2.0, Smart Sys Care, and Inlog Optimizer are some examples of apps similar to System Cleanup. Despite how good these offers may sound, in most cases, the features are nonfunctional.

The only purpose of all unwanted software/files is to generate profit for the developers. Regular users receive no real value. In summary, PUAs cause redirects, deliver intrusive ad campaigns, and collect sensitive data.

How did potentially unwanted applications install on my computer?

As mentioned, System Cleanup has an official download website. PUAs also spread via download/install set-ups of other programs. By rushing through the download/installation processes (e.g. ignoring terms, skipping steps and sections, using pre-set options, etc..), many users unintentionally allow "bundled" content into their devices.

Intrusive advertisements can also download and install PUAs without users' permission. Once clicked, they can execute scripts to perform these rogue downloads/installs.

How to avoid installation of potentially unwanted applications

Your content should be researched to verify its legitimacy, before downloading/installing. Only official and verified download sources should be used. Peer-to-Peer sharing networks (e.g. BitTorrent, eMule, Gnutella, etc.), free file-hosting and unofficial sites, third party downloaders and similar sources are untrustworthy and should not be used.

When downloading/installing, read the terms, explore possible options, use "Custom/Advanced" settings, and opt-out of downloading/installing additional content. Intrusive advertisements typically seem normal and harmless, however, they can redirect to dubious web pages (e.g. pornography, adult-dating, gambling, etc.).

If you encounter these ads/redirects, check the device and remove all suspicious applications and/or browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
