Chistilka removal instructions

What is Chistilka?

Chistilka (Чистилка) is a piece of software requiring no installation and endorsed as a system cleaner. It is supposedly capable of removing undesirable advertisements (pop-ups and similar), as well as boosting the speed of the Windows OS (operating system). It is promoted through its official website and can be inadvertently downloaded as a supplement to other software. This mode of proliferation, through the download/install setups of ordinary programs is called "bundling". Said deceptive marketing method is prominent amongst PUA (potentially unwanted application) developers, who are well aware of user tendency to rush through aforementioned setups - thereby unwillingly exposing their devices to various invasions. Due to its stealthy infiltration, Chistilka is classified as a PUA.

Chistilka unwanted application

The first thing Chistilka performs is a scan, afterwards listing the threats/issues it finds (e.g. malware and other malicious content, as well as damaged, oversized files and etc.) However, in order to fix said issues it requires activation, i.e. users need to buy the activation key to active Chistilka. It must be stressed, that it is unknown whether this cleaner is fraudulent or not. It is entirely possible that the issues it detects are imaginary and the features it boasts are nonfunctional. PUAs are not to be trusted, therefore it is strongly advised against downloading and purchasing this piece of software. It is noteworthy, that download/install packs used to further apps like this one often contain more than one PUA (commonly, browser hijackers and/or adware). Unwanted applications have many heinous abilities. They can generate redirects to various sale-oriented, untrustworthy and even malignant sites, hijack browsers, deliver intrusive advertisement (pop-up, banner, survey, coupon and similar) campaigns. Some can even track data; information of interest being users' browsing activities. It is crucial to know that browsing habits contain traces of personal information. Since all the gathered data is sold to third parties, it can easily end up serving criminal purposes. Therefore, data tracking can lead to serious privacy issues, even culminate in identity theft. To ensure device and user safety, all dubious apps and likewise suspicious browser extensions//plug-ins must be removed immediately.

There are thousands of PUAs, many share similarities and some are even identical. Comparable to Chistilka are: SweepTools PC CleanerAdroit System CareOne Click SpeedupXtron System Care and others. While the abilities/features they advertise differ, their purpose is the same. It must be emphasized, that in most cases all the features they claim to have are merely a guise, i.e. nonfunctional. They are designed to generate revenue for their developers, therefore to users they have no genuine value. Instead of delivering on any promises, unwanted apps cause redirects to unreliable/malignant websites, run invasive advert campaigns and track sensitive data.

How did potentially unwanted applications install on my computer?

As mentioned previously, Chistilka can be downloaded from its official site or invade systems alongside other software. The latter is a false marketing method termed "bundling", by which ordinary programs are pre-packed with PUAs. Rushing through the downloading/installation process (e.g. ignoring terms, skipping steps, using pre-set options, etc.) can expose devices to possible infiltrations. Opt-outs from these undesired additions are often possible, however they are frequently hidden behind "Custom/Advanced" settings and other similar options. Another way that PUAs spread is through intrusive advertisements. By clicking on such ads, users can trigger them to execute scripts, designed to make rogue downloads/installs.

How to avoid installation of potentially unwanted applications?

It is strongly recommended to use only official and verified download sources, ideally via direct download links. Users are urged not to use peer-to-peer sharing networks and other third party downloaders, as they are more likely to offer bundled content. When installing software, users are advised to read terms and explore possible options. Additionally, they should use "Custom/Advanced" install settings and opt-out from downloading/installing supplementary apps and/or features. It should be known that intrusive adverts typically look very legitimate and harmless, therefore they are easy to be tricked into clicking. However, a telltale sign of an invasive advertisement can be the questionable websites it redirects to (e.g. pornography, adult-dating, gambling and etc.). To stop suspicious ad campaigns and unauthorized redirects, users are recommended to inspect their system and remove all dubious 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.
