removal by Lucia Danes - - | Type: Browser hijacker

Search.searchquco.com is browser hijacker that forces to use a questionable search engine

Search.searchquco.com search engine

Search.searchquco.com is a potentially unwanted program (PUP)[1] that spreads bundled with free programs and can hijack targeted web browsers. Due to its ability to change default search engine and homepage, it is known as a browser hijacker.

Summary
Name Search.searchquco.com
Developer Polarity Technologies Ltd.
Type Browser hijacker
Danger level Medium. Takes control of the affected browser and makes modifications to the system
Symptoms Default homepage, search engine and new tab URL address with its domain, reverts user's attempts to set preferred search tool, displays commercial content
Distribution methods  Software bundling
To remove Search.searchquco.com, install Reimage and run a full system scan

Search.searchquco.com virus spreads in the form of a browser extension called Quick Coupons which seems to help people to find discounts and best online shopping offers. After the installation of this add-on and system restart, users can find unknown search engine instead of their default one.

The Search.searchquco.com might look like an ordinary search tool that offers quick access to social networks and mailing services. However, it’s just another Yahoo-based search engine created by Polarity Technologies. This company is known for creating numerous similar tools to participate in Yahoo affiliate program and generate per-per-click revenue.

To achieve this goal, authors of the browser hijacker created a tool that after infiltration might:

  • take control over the affected browser by altering system settings and browser’s shortcuts;
  • set either http://search.searchquco.com or http://query.searchquco.com as built-in search tool;
  • replace startup page to one of the previously mentioned domains;
  • prevent users from setting their preferred homepage and search engine;
  • display ads and other commercial content;
  • redirect to affiliate websites;
  • track and share information about users;
  • allow third-party tracking technologies.

Browser hijacker cannot cause direct damage to the computer or files stored on the affected device. However, Search.searchquco.com redirect tendencies might lead to infiltration of one of these cyber threats. According to the analysis, this tool can redirect to infected or at least potentially dangerous sites that are used for spreading malware.[2]

Security specialists highly recommend staying away from ads, pop-ups, and banners because they might be misleading and created to get your click. This PUP is capable of tracking information about user’s browsing history and preferences and using it for targeted advertising. For this reason, ads might seem interesting and useful, but in reality, they might lead to malware-laden sites.

To avoid privacy and security issues, you should remove Search.searchquco.com with all its related components from the system. Probably, you have tried to get rid of it by replacing this domain with your preferred domain, but it was not enough.

Indeed, elimination requires putting more effort. You have to either follow manual Search.searchquco.com removal guide given at the end of the article or run a full system scan with Reimage.

The sneaky way how hijacker enters the system unnoticed

Browser hijackers just like thousands of other PUPs usually arrive in the system with the help of freeware and shareware. The program can get into the system when users download any free software using Quick/Recommended settings. Security experts from bedynet.ru[3] warn that this setup does not reveal what PUPs might be included in the software package.

Keep in mind that any free program can be a “package,” not a single program. Thus, you have to always check it by using Advanced/Custom settings. Follow the installation guide attentively, and remove the ticks from pre-selected optional downloads. Simple as that, your computer is protected from unwanted ads.
