KeyBTC virus: how aggressive is it?

There is a recent boom among ransomware and KeyBTC virus happens to be one of the new ones. This virtual threat is programmed to infect computer and lock valuable data. Moreover, the ransomware seems to be a new headache for cyber security specialists since it behaves differently than other viruses of the same kind. If you are reading this article, most probably, your data is locked by this virus as well. Thus, here you will find out about KeyBTC removal methods.

Let us start with the prevailing peculiarities of this ransomware. KeyBTC ransomware might look intriguing as it doesn‘t act the same way as other ransomware. First of all, let us discuss the ransom issue. Contrary to other viruses which instantly declare the amount of money, this malware asks you to contact the developers by this provided email — keybtc@inbox.com. All the encrypted files are put into File1.bin and File2.bin. Afterward, if you are desperate to retrieve them and send the email with the attached files you receive a reply with the indicated amount of ransom and further instructions to remit the payment. Some might speculate that these spurts of new ransomware might be the wrongdoings of the same hackers since currently released ransomware use emails for contacting rather than anonymous browsers or domains. Thus, it might be one of the weaknesses of the ransomware. Detecting the source of infection might be easier. Additionally, KeyBTC malware attaches its .keybtc@inbox_com extension to the encypted files. Cyber security specialists have also revealed that the virus mainly targets the files with these extensions: .mdb , .pdf , .rtf , .accdb , .slddrw , .zip , .rar , .max , .jpg , .xls , .xlsx , .doc , .docx , .cdr , .dwg , .1cd , .cd. Thus, its target scale is smaller in comparison with other ransomware.

The example of KeyBTC virus

The transmission ways of KeyBTC

The virus has been spotted traveling via infected spam emails. Often they contain a zip folder which has a .doc or .js file in it. You should be alert if you receive an email from an unknown address entitled as Postal_Notification__0000863254.doc.js. Be aware that hackers have developed persuasive techniques to convince users into opening the emails. They might look like postal notifications, shipment reports or fake invoices. Thus, stay vigilant and avoid opening them. In case it is already too little too late for such advice, you might be interested to know that KeyBTC starts downloading malicious files on your system to root deeper into your computer. After the files are encrypted, you should not foster any hopes that hackers will return the data even if you make the financial transaction. There are some programs (PhotoRec, R-Studio, etc.) which are designed for data recovery. However, we do not give any guarantees that it will succeed in decrypting the files or recovering them. Likewise, it would be wiser to think about possible ways to remove KeyBTC. You can use Reimage for such purpose.

Is there a way to remove KeyBTC?

Mainly, there are two solutions — automatic and manual elimination. If you opt for manual method, keep in mind that you must delete all the files associated with KeyBTC virus. Some users might struggle to identify the malignant files from legitimate. Thus, you may accidentally delete registry files. Such mistake only worsens the situation. That is why we suggest saving time and energy by opting for KeyBTC removal. An anti-spyware program will eliminate the virus permanently in the relatively short period of time. After your system gets to its previous mode, make sure to use a back-up function to create copies of your important information.
