HKGT is a ransomware from the STOP/DJVU family that will take over your computer functionality and lock your computer until you pay a “ransom” in order to get access back. What it does is encrypt all user files with the .hkgt extension and leaves a _readme.txt file which contains contact details and payment info. It disguises itself as a legit official warning when in reality it is all fake. Don’t fall for the trap and don’t pay any ransom fees. With software, you can remove the HKGT ransomware easily.
This type of infection can be downloaded on your computer for many reasons such as malicious websites, codecs, or downloads. Be sure to remove it immediately.
