The infection with such a virus is always a great surprise, as the ways it can spread imply a imply a stealth. For example, hackers widely use various executable files, which are made as if it some official installer of a famous program or something necessary for the system. Moreover, they often send the virus by email. For this purpose, they inject the code of the virus into a regular harmless file. In this case the virus activates, once the file has been opened. If BigLock successfully got into the system, it begins to modify Registry keys and tries to infect important system processes. By the means of it, the virus stays unnoticed by the built-in system protection. Then AZOR scans the hard drive and searches for the definite files. Such files, as the rule, are documents and media files. Later, BigLock modifies file structures and adds the “.corona-lock” extension to the file names. This is the clearest sign of the infection with BigLock ransomware. Next the virus drops the ransom note called “README_LOCK.TXT”, by the means of which criminals try to make victims pay for the decryptor. Unfortunately, it’s the surest way to decrypt your files, but in the most cases, criminals don’t respond to the messages after being paid. Moreover, they can make the situation much worse.
