Qmak Virus – Main Activity
Qmak virus is part of the large family of malware known as DJVU. It includes hundreds of variants, like the recently detected .cool, .palq and .vtua. Just like these variants, the virus may spread via one of the two main strategies that are most often used by crypto viruses:
- If you have received it as an e-mail attachment or a link sent in a spam message.
- In case you have downloaded it from some third-party websites offering freeware executables.

- Work-related documents.
- Invoice of some sort.
- Tickets for flights.
- Purchase e-receipt.
However, one of the most often used methods by malware authors to infect computers is to upload the files on some websites that offer free downloads. According to our research, the most often infected victims by this particular virus have often downloaded executable files, such as:

- Documents (.docx, .pptx, etc.).
- Images (.jpg, .png, .etc).
- Video objects (.mp4, .avi, etc.).
Once it has selected the files, the virus changes key data in those files and the outcome of this is that they begin to appear like the following:
Removing the file extension will not fix your problem as these files have blocks of data in them changed by the encryption mode used by this virus which is known as AES or Advanced Encryption Standard. The only actual solution remains to be a description software that is able to get the files back by reversing the encryption process.
