System Cleanup removal instructions

What is System Cleanup?

System Cleanup is a piece of software, promoted as a system cleaner and optimizer. It is supposedly capable of scanning systems and removing "junk" and temporary files, as well as other unnecessary data. This program has an official webpage, where it can be downloaded for free (or users can purchase the "premium" version). However, System Cleanup can also be installed alongside other software. This deceptive marketing method of packing regular programs with undesirable content is called "bundling". Rushed download/installation processes increase the risk of such infiltrating devices. Due to its dubious mode of proliferation it is considered to be a PUA (Potentially Unwanted Application).

System Cleanup unwanted application

Due to System Cleanup's classification as a PUA it is deemed to be untrustworthy and may also be a threat to device and/or user safety. It is strongly advised against downloading/installing this application and others similar to it. Most PUAs of this type require to be activated, in other words they need to be purchased. However, despite being purchased, they often do not work as advertised or are outright nonoperational. Furthermore, download/install setups used to proliferate System Cleanup, frequently contain more than one PUA (e.g. browser hijackers or adware). These unwanted applications have many harmful abilities. They generate redirects to various sale-oriented, untrustworthy and even malicious webpages. Additionally, by using a variety of tools they enable third party graphical content and deliver intrusive advertisement campaigns (e.g. pop-ups, surveys, banners, coupons, etc.). These ads seriously diminish browsing quality, by limiting browsing speed and overlaying page content. They also generate redirects to hazardous sites and can execute scripts to stealthily download/install PUAs. Unwanted applications have another heinous ability - data tracking. By recording browsing activity (URLs visited, pages viewed, search engine history, etc.), they gather users' personal information (IP address, geolocation and personal details). This private data is then shared with third parties (potentially, cyber criminals), seeking to misuse it to generate revenue. Therefore, PUAs can cause system infiltrations and infections, as well as lead to severe privacy issues (even identity theft). To ensure device and user safety, all suspicious applications and browser extensions/plug-ins must be removed immediately.

In general, PUAs tend to be quite similar. They are designed to appear legitimate and offer a broad array of "useful" and "beneficial" features. Full PC Care 2.0Smart Sys CareInlog Optimizer are a few examples of apps similar to System Cleanup. Despite how good their offers sound, users should note that in most cases all their features are nonfunctional. The only goal of all undesirable content is to generate profit for its developers; to users it has no genuine 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 proliferate via download/install setups of other programs. By rushing through the download/installation processes (e.g. by ignoring terms, skipping steps and sections, using pre-set options and etc.) - users can unintentionally allow such "bundled" content into the device. Intrusive advertisements can also download and install PUAs without user permission. Once clicked, they can execute scripts, designed to make such rogue downloads/installs.

How to avoid installation of potentially unwanted applications?

Desired content should always be researched in order to verify its legitimacy, before downloading/installing it. 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 deemed to be untrustworthy; therefore are advised against use. When downloading/installing, users are recommended to read terms, explore possible options, use "Custom/Advanced" settings and opt-out from downloading/installing additional content. Intrusive advertisements typically look ordinary and harmless, however they redirect to various dubious webpages (e.g. pornography, adult-dating, gambling and etc.). Should users encounter such ads/redirects, they are strongly urged to inspect 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 Spyhunter for Windows to automatically eliminate them.
