Check and Switch removal instructions

What is Check and Switch?

Check and Switch is a deceptive application that supposedly helps to fix grammatical errors in text. This functionality may seem legitimate and useful, however, Check and Switch often infiltrates systems without permission. In addition, it delivers intrusive advertisements, gathers sensitive information, and reduces system performance. For these reasons, Check and Switch is categorized as a potentially unwanted program (PUP).

Check and Switch adware

The presence of Check and Switch adware affects system performance considerably. At time of testing, this app consumed over 50% of CPU resources. Although there are a number of causes, PUPs are likely to be mining various cryptocurrencies on the system. The mining process can take up to 100% of CPU resources, making the system unstable (it might freeze, leading to permanent data loss). Furthermore, components that run at maximum capacity generate excessive heat. Therefore, in certain circumstances (bad cooling systems, high room temperatures, etc.), computer components may over heat. Thus, the presence of cryptomining PUPs can lead to significant financial/data losses. Furthermore, some anti-virus/anti-spyware suites detect Check and Switch as a "trojan downloader". Therefore, this PUP might be capable of infiltrating other viruses into the system. As mentioned above, Check and Switch is also used to deliver intrusive advertisements. These are displayed using tools that enable placement of third party graphical content on any site. Most conceal underlying content, significantly diminishing the web browsing experience. Furthermore, these ads redirect to infectious websites and execute scripts that stealthily download/install malware. Therefore, clicking them risks various system infections. Check and Switch also gathers information relating to web browsing habits. The information typically includes personal details that developers sell to third parties (potentially, cyber criminals) who misuse it to generate revenue. Therefore, having a data-tracking app such as Check and Switch installed on your computer might lead to serious privacy issues or even identity theft.

Check and Switch is virtually identical to GeoSmartDNS, SuperSearch, FastDataX, and dozens of other adware-type applications. All offer "useful features", and yet these programs are designed only to generate revenue for the developers. Adware gives no real value for regular users, delivers intrusive ads, and gathers sensitive information, thereby posing a direct threat to your privacy and Internet browsing safety. Claims to enable "useful functions" are merely attempts to give the impression of legitimacy.

How did Check and Switch install on my computer?

Users can download Check and Switch on its official website, however, this app is also distributed using intrusive advertising and "bundling" methods. Therefore, it often infiltrates without consent. "Bundling" is essentially stealth installation of third party applications together with regular programs. "Bundled" apps are hidden within various sections (usually "Advanced" or "Custom" settings) of the download/installation processes. Furthermore, many users rush these procedures and skip steps. In addition, they often click advertisements without understanding the possible consequences. This behavior often leads to inadvertent installation of PUPs - users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

To prevent system infiltration by PUPs, be very cautious when browsing the Internet and downloading/installing software. Intrusive ads typically seem legitimate, but most redirect to dubious websites (gambling, pornography, survey, etc.) If you encounter these redirects, check the list of installed applications and browser plug-ins. Furthermore, analyze each window of the download/installation dialogs and opt-out of all additionally-included programs. In addition, never use any third party download/installation tools, since they are likely to "bundle" PUPs. Software should be downloaded from official sources only, using direct download links. The key to computer safety is caution. If your computer is already infected with Check and Switch, we recommend running a scan with Spyhunter for Windows to automatically eliminate this adware.
