Mik Virus (. miK Files) — How to Remove Virus?

What is Mik?

Mik adds its own .miK extension to every file’s name. For example, an image entitled “photo.jpg” will be turned into “photo.jpg.miK”. Likewise, the Excel table with the name “table.xlsx” will end up as “table.xlsx.miK”, and so on.

In each folder containing the encrypted files, a ДЕШИФРАТОР.txt file will be created. It is a ransom money memo. It contains information on the ways of paying the ransom and some other remarks. The ransom note usually contains instructions on how to purchase the decryption tool from the Mik developers. That is how they do it.

In the screenshot below, you can see what a folder with files encrypted by the Mik looks like. Each filename has the “.miK” extension appended to it.

How did Mik ransomware end up on my PC?

Nowadays, there are three most exploited methods for tamperers to have the Mik virus planted in your system. These are email spam, Trojan infiltration and peer-to-peer networks.

If you access your mailbox and see letters that look like familiar notifications from utility services companies, delivery agencies like FedEx, web-access providers, and whatnot, but whose “from” field is unknown to you, be wary of opening those emails. They are very likely to have a ransomware file attached to them. Thus it is even riskier to download any attachments that come with emails like these.

Another option for ransom hunters is a Trojan file model³. A Trojan is an object that infiltrates into your computer disguised as something legal. For example, you download an installer for some program you need or an update for some software. However, what is unpacked reveals itself a harmful agent that encrypts your data. As the installation package can have any title and any icon, you have to make sure that you can trust the resource of the things you’re downloading. The best way is to trust the software companies’ official websites.

As for the peer file transfer protocols like torrent trackers or eMule, the threat is that they are even more trust-based than the rest of the Web. You can never guess what you download until you get it. Our suggestion is that you use trustworthy resources. Also, it is reasonable to scan the directory containing the downloaded objects with the antivirus as soon as the downloading is done.
