What is Quick Searcher?
Quick Searcher is a deceptive application that claims to enhance the browsing experience by enabling selection of text as a search query in Google simply by clicking Ctrl+Q.
This feature may seem legitimate and useful, however, Quick Searcher delivers intrusive advertisements, changes browser settings, gathers sensitive data, and misuses system resources to mine cryptocurrency. Furthermore, this app is likely to infiltrate systems without permission. Therefore, Quick Searcher is categorized as adware and a potentially unwanted program (PUP).
Following infiltration, Quick Searcher feeds users with intrusive advertisements (coupons, banners, etc.) To achieve this, developers employ various tools that enable placement of third party graphical content on any visited website. Therefore, intrusive ads often conceal underlying website content, thereby diminishing the web browsing experience.
Furthermore, intrusive ads can lead to malicious sites and even execute scripts that download/install malware or PUPs. Even a single accidental click can result in high-risk computer infections. As mentioned above, Quick Searcher modifies web browser options by assigning the new tab URL and homepage browser options to a fake web search engine.
Thus, users are forced to visit Quick Searcher's site when they open a new browser tab/window. Another important issue is crypto mining. Quick Searcher injects all visited websites with a script that employs the CPU to mine Monero. The mining process is active as long as the browser is opened. During the process, the CPU use can reach 100%.
Therefore, the system becomes unstable (freezes, crashes, etc.), possibly leading to permanent data loss (unsaved projects/documents and similar). Furthermore, a CPU working at maximum power generates extensive heat.
Within certain circumstances (high room temperatures, bad cooling systems, etc.), this behavior can result in damaged hardware (overheating). Note that Quick Searcher notifies users that the mining scripts are executed, however, many users ignore such pop-ups/notifications. In this way, Quick Searcher easily gathers information relating to web browsing activity.
IP addresses, website URLs visited, pages viewed, search queries, and other collected data often includes personal details that are shared with third parties (potentially, cyber criminals) who misuse private data to generate revenue.
The presence of data-tracking apps such as Quick Searcher can lead to serious privacy issues or even identity theft. Therefore, we strongly advise you to uninstall Quick Searcher adware immediately.

Although Quick Searcher is quite advanced adware (it has more features that usual), it shares many similarities with ArcadeGoNetwork, Pokki, Update Checker, Current Me, and dozens of other PUPs. As with Quick Searcher, these apps offer useful functions, however, these claims are merely attempts to give the impression of legitimacy.
Adware-type apps are designed only to help developers generate passive income. These programs provide no real value for regular users, but pose a direct threat to their privacy and Internet browsing safety.
How did Quick Searcher install on my computer?
As mentioned above, Quick Searcher typically infiltrates systems without consent. Developers proliferate this PUP using "bundling" and intrusive advertising methods. "Bundling" is essentially stealth installation of unwanted apps with regular software.
Developers hide "bundled" PUPs within "Custom/Advanced" settings or other sections of the download/installation processes - they do not disclose these installations properly. Many users rush these procedures and skip steps. Furthermore, they click various "tempting" (yet suspicious) links/ads without understanding the possible consequences.
This behavior often leads to inadvertent installation of PUPs such as Quick Searcher - 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 cautious when browsing the Internet and downloading/installing software. Intrusive advertisements typically seem legitimate, but once clicked, redirect to gambling, pornography, adult dating, and other dubious websites. If you experience these redirects, immediately eliminate all dubious applications and browser plug-ins.
Furthermore, select "Custom/Advanced" settings and carefully analyze each window of the download/installation dialogs. Decline offers to download/install additional applications and opt-out of those already included. Software should be downloaded from official sources only, using direct download links.
Third party downloaders/installers are monetized using the "bundling" method (promoting PUPs), and thus should not be used. The key to computer safety is caution.
