How did I get infected with?

To travel the web, JS:Miner-E uses corrupted spam email attachments. You have heard it a thousand times, yet you will hear it once more: do NOT open emails from strangers. Verify the sender first. You can simply enter the questionable email address into some search engine. If it was used for shady business, someone must have complained online. Also, the crooks tend to write on behalf of well-known organizations and companies. If you receive an email from your bank, for example, do not rush into action. Go to their official website and compare the email addresses listed there with the one you have received a message from. If they don’t match, delete the pretender. Furthermore, a trustworthy organization would use your real name to address you. If the letter stars with “Dear Customer” or “Dear Friend,” proceed with caution. Do not download anything. If the email contains links, don’t follow them. The hyperlinks may be corrupted, or they may lead to infected websites. Your first step should always be the verification of the sender. When you download files, scan them with anti-virus software. The key to clean, virus-free computer is caution. Always do your due diligence!

Why is this dangerous?

JS:Miner-E is a menace. This Trojan enters your computer in complete silence and roots deep into your system. It is using your computer resources without permission and leaves your PC useless. To carry out its malicious processes, however, the Trojan needs one more thing — electricity. It may sound odd, but such is the reality. The Trojan can double, even triple, your electricity bill. But what do you think happens with this electricity. Your computer turns it into heat. If your cooling system is not efficient enough, your device will crash. What is worse, the Trojan will not hesitate to use your CPU under high temperatures. This will shorten your device’s life significantly. If you don’t remove the Trojan promptly, it may even cause irreversible damage to your hardware. As we already explained, the mining process is only profitable if you don’t use your resources. You paid for the hardware and the electricity. Yet, it is the crooks that make the mint. Do not allow this to continue any longer. Remove JS:Miner-E[Trj] immediately.
