Infected with CtrlAlt Ransomware? Need to decrypt your files?

What is CtrlAlt Ransomware

Recently, various potentially unwanted programs and adware is gaining momentum, however, ransomware viruses are the most dangerous. Directly in this article, we will talk about CtrlAlt Ransomware (also known as District Ransomware). CtrlAlt Ransomware has spread around the world almost despite the fact that it is initially aimed at English-speaking users. For a start, I would like to remind you that the cryptovirus encrypts all user data, including office, archive, audio, video documents. After encryption, this changes the file extension by adding a prefix. After that, of course, the files become unsuitable for further use. In particular, this cryptovirus adds .сtrlalt@cock.li.district extension. Recently, according to our newest data, it has been noticed that it can use the .altdelete@cock.li.district extension. After encryption, the cryptovirus creates a ransom note. In the original version, this is the READ_IT.district file indicated below:
