In order not to become a victim of a virus-extortionist, it is necessary to adhere to the most simple, but at the same time, effective advice.
The rules are as follows:
do not open attachments, do not follow links from letters from unverified and unknown senders;
carefully read system notifications and if something is not clear to you - better press "NO" and consult with specialists;
do not update Adobe Flash in the next few weeks.
To reduce the risk of infection with the aforementioned viruses, it is advisable to implement the following recommendations:
block Internet access for all processes except the minimum ones (use the "white list");
configure as main DNS-servers the addresses of the OpenDNS service (for example, 208.67.222.222);
block execution of files with the names C: \ windows \ infpub.dat and C: \ Windows \ cscc.dat;
block the launch of executable files in the% appdata% and% temp% directories;
block (if possible) the use of the WMI service.
