Ykcol Ransomware is a dangerous and severe threat that is indeed a new variant of the infamous Locky Ransomware. The creators seem to lack creativity and ended up with a reversed name of the original vicious program. Unfortunately, this ransomware can be rather destructive as it encrypts all your important files that cannot be recovered without the unique decryption key and decryption tool, which are stored on a secret remote server and can only be accessed by these cyber criminals. It is a real nightmare if you do not have a recent backup saved on a removable drive or in cloud storage because you could lose all your personal file in this malicious attack. Even if you are offered the key and the tool by these crooks for a rather high price, we do not advise you to pay them because there is never any guarantee that you will really get anything as promised. It is more likely to get further infections from such criminals than anything you could recover your files with. And, it is even more likely that you will never hear about them again. This is why we encourage you to act and remove Ykcol Ransomware right away so that you can restore your PC and copy your backed up clean files back if you have any.
It is most probable that you have opened a spam mail recently and saved its attachment. This spam can claim that it is related to some problematic invoice, such as an unpaid, overdue invoice. Obviously, the attached file is supposed to be a proof of that, i.e., the invoice in question. This file attachment may be an image, a document, or a ZIP file of some sort. You should never open a mail that you have any doubts about because it can end very badly for you like in this particular case. Whenever you are in doubt, you should always contact the sender to send you confirmation that this mail was meant for you personally. Of course, this spam can appear to be very convincing and misleading as even its sender name and e-mail seems authentic so why would you question it, right? The subject is also chosen to possibly relate to anyone. This is why so many users fall for this trick; even more experienced computer users. Please note that you cannot delete Ykcol Ransomware from your system without losing your files to encryption unless, of course, you have a backup. Remember that deleting this dangerous threat does not recover your encrypted files. This is why it is vital to prevent such an attack from happening by being more cautious and possible installing a decent anti-malware program to protect your PC.
This malicious program uses a combination of AES-128 and RSA-2048 algorithms to encrypt your important files, such as you photos, videos, documents, databases, and archives; well, the usual files targeted by most ransomware programs really. These are the files that some victims are ready to pay for to get back. The encrypted files are easy to spot as their name changes to a long code of letters and numbers plus a ".ykcol" extension to look something like "1R3CK50J-WX31-76KX-0FF2943B-B6A0A941AC64.ykcol." This dangerous infection drops two files onto your system. Both files are the ransom note but in different forms. One file is a .bmp called "ykcol.bmp" and is created on your desktop; this file is the one that replaces your desktop background once the encryption is over. The other file is an .htm file called "ykcol-abc9.htm," where "abc9" can be any random characters, and it is placed in every folder that has been affected by this threat.
When the encryption is over, your desktop background changes and your default browser is also opened with the ransom note .htm file. Basically, both the background image and this .htm file contains the same ransom note information and instructions. You have to download the Tor browser in order to be able to visit the website where you can learn about the payment. You have to pay 0.25 BTC (around 1,078 USD) to receive the decryption key and tool so that you can decode your encrypted files. However, we believe and experience shows that it is always risky to pay such criminals because you may be simply scammed and you will never see your files again anyway. So, if you do not want to lose your money as well, we suggest that you remove Ykcol Ransomware immediately from your PC.
