Enormous hike in prices of cryptocurrency over the year has turned many into billionaires overnight. Leading cryptocurrencies include Bitcoin, Ether, Litecoin, Monero, Ripple and many more.
What is Cryptojacking?
The trade world of cryptocurrency has come across to a newer phenomenon called cryptojacking where scammers use your computer’s resources to mine cryptocurrency in your browser thus compromising your online security.
The cryptojackers, as those scammers are called in crypto-world, normally use porn sites for their evil deed of mining without your approval and even when your browser is closed. But a number of blogging websites have also been reported doing the same.
Why to Block Cryptojacking?
As mentioned earlier, the scammers can hike into your machine through your browser and do crypto-mining, an extremely resource-intensive process that may overwork your PC’s processor while draining system resources and damaging your hardware.
In other words, your computer will be used by someone else without your notice through a malicious website, in many cases running crypto-mining scripts on your computer.
How to Block Cryptojackers?
If your PC or laptop slows down while accessing a specific website, chances are there that the website is using scripts to mine cryptocurrency using your processor.
You can check your CPU utilisation in Windows Task Manager by tapping Ctrl+Alt+Delete on keyboard and selecting “Performance” tab in the Task Manager for Windows 7, 8 and 10.
If the “CPU Usage” reads around 80-90% while viewing a certain website, beware that your system resources are being used in the background.
Fortunately, browsers like Google Chrome and Mozilla Firefox support add-ons doing the job whereas Opera comes with pre-installed tools to protect you from cryptojacking:
- Google Chrome does not come with a built-in crypto mining blocker but you can use an add-on Crypto Miner Blocker to protect your computer from being hacked into.
- Likewise, Mozilla Firefox has no built-in blockers but the NoMiner plugin may be used to get rid of cryptojacking.
- Opera, on the other hand, comes with built-in crytojacking blockers for desktop version’s beta build as well as Opera Mini for Android | iOS and Opera Browser in Android.
