Today I will talk about another free antivirus Avira Free Antivirus, which recently settled on one of my computers. The situation with it is special, since this antivirus is not a simple scanner, it does not need to be downloaded every time you need to check the system. This antivirus hangs in memory and does everything on its own. Independently downloads and installs updates, independently checks files accessed by the operating system and various applications.

A massive attack by the WannaCry ransomware (WannaCryptor, WanaDecryptor) led to the infection of tens of thousands of computers in organizations and public institutions around the world. The malware uses a known vulnerability described in security bulletin MS17-010 and a combination of EternalBlue/DoublePulsar exploits, which allows it to attack other vulnerable Windows systems on the same network. As a result, infection of one computer can lead to compromise of the entire corporate network In the organisation.

Once a vulnerability appears on a computer due to successful exploitation, WannaCry ransomware encrypts all files and documents of certain formats, performing remote commands, sent over the SMB protocol, and spreading to others Windows computers online.

Perhaps you are too trusting and therefore have not installed an antivirus on your PC, or the license for your antivirus has already expired, or the antivirus you have installed does not provide maximum protection, and... maybe your PC is infected!
