By continuing to use the extension, you are agreeing with the rules”. This means you should check the list of active add-ons. If you notice Quick Searcher extension, please hurry up and remove it.

As we have always reminded our users, crypto-mining is a legitimate activity if program or website owners receive consent from users to initiate it. If this permission is not granted, then the mining occurs without approval and users are not informed of it (Cryptojacking lets strangers mine). This is the same for Quick Searcher extension: it does not inform its potential clients about a crypto-miner. Crypto-Loot is another miner that might compromise your browsing experience.

Users are informed about a miner after it is injected. This is not an appropriate method of delivering crypto-miners. You might think that it is no big deal that your CPU resources will be used for mining. However, you will soon notice that this feature is complicating your browsing activities.
Infected browsers will require more time to be launched.

If you regularly launch a multitude of programs, your it will be very difficult to switch from one to another.

The corporation plans to develop a permission to block crypto-miners and put an end to in-browser mining Trojans.

Put a stop to crypto-miners and other potentially unwanted programs (PUPs)

Currently, users can block crypto-miners via AdBlockers. This is a very convenient feature to consider if you do not want to have your CPU resources exploited for illegal purposes. In addition to this, some antivirus programs are also starting to feature miner-blockers. If Google succeeds and provides users with an ability to block miner, then avoiding these vicious Trojans will be way easier.

On the other hand, you might be offered to install a malicious or potentially unwanted tool via Setup Wizard of another program. Choose advanced/custom modes to be able to properly review the installation process. If additional programs or browser extensions are proposed, please refuse them.
