The secret of Quick Searcher – a hidden CPU miner

The image representing Quick Searcher extension

Quick Searcher virus functions as a browser extension which has a significant drawback – it mines crypto-coins[1]. It is promoted as a handy browser assistant which facilitates browsing process. However, it does more than that.
Once you install it, an additional message will appear in every web page:

Our extension uses your CPU power to mine cryptocurrency. By continuing to use the extension, you are agreeing with the rules.

The boom of hidden crypto-coin miners

Interestingly, there is no mention of such behavior in the description of the plug-in. You cannot find it in Chrome or other browser’s web store. On the other hand, it is very likely to lurk in gaming, gambling or websites promoting adult content.

Proportionally to the hike of bitcoin price[2], hidden crypto-miners have become a new wave among cyber criminals[3]. Now they tend to shell miners with apps or browser extensions.

The key problematic aspect that miners tend to “generate” coins on behalf of visitors’ PC energy resources – particularly, CPU. Therefore, you might get an urge to remove Quick Searcher from the browser ASAP. Updated security apps, such as ReimageIntego or Malwarebytes, will assist you in this procedure.

Unfortunately, cybersecurity experts have also detected more than 200 websites containing the miner script. Some of their domains are hacked and the site script compromised with the miner, while others deliberately place the script, however, without informing visitors.

When it comes to hackers, the greed for money might encourage them to employ vivid malware to direct users to specific crypto-mining sites. Considering a great number of legitimate sites engaging in such business, there is also a possibility that some of them might team up with felons.

Ways to detect miners

This crypto-coin mining extension also has alternative name – Quick Searcher CPU miner. It also suggests the aspect how you can determine its real origin. If you notice one of the browses web pages consuming more than 30% CPU resources, it is a direct sign that this or another miner is draining the energy from your PC.

Note that there are a number of other extensions which bear miners, e.g., Safe Search. Even if you do not have any of these extensions present on the system, but the computer crashes regularly, and new web pages take an eternity to load, take anti-miner measures.

If you tend to install new extensions, check their rating, users’ reviews in (various forums), and privacy policy. The same applies to downloading new apps or using specific website’s services. Finally, since this miner is also called Quick Searcher Miner Trojan, you should be wary of trojans as well. Security tools will help you evade them. Now let us discuss Quick Searcher removal options. The picture suggesting Quick Searcher Miner TrojanQuick Searcher crypto-coin miner, unfortunately, is only one of numerous samples present in the cyberspace.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
