Yeah! I do. Thank you.

To prevent, protect and raise awareness, it is necessary to estimate the damage that this virus will cause and to charge this amount from the US Government and Microsoft.

Microsoft has created a "flaw", a port for the NSA to spy on governments and businesses around the world. When the "software", created by the NSA, to use that port was hacked, the NSA informed Microsoft that it released a patch to "fix the flaw". And did it quietly, not to arouse suspicion.

This distinguished company still tried to get high gains with the misfortune of others by selling patch to OS prior to the W7. Until a young Englishman created a key to unlock hijacked computers. And this patch became free.

Do you want to criminalize the hacker who is hijacking computers? Wrong! Be grateful to him as you should be to Snowden.

However, since we believe that the infection and propagation rate may go up on Monday when people return to their workplaces, we would like to ask you to please help us distribute information that can help contain this threat. To this end, we have compiled a list of recommendations and also prepared an infographic (see attachment). Please feel free to use this information for reaching out to your network and to complement your advice, if and where useful.

> Back-up! Back-up! Back-up! Have a backup and recovery system in place so a ransomware infection can?t destroy your personal data forever. It?s best to create at least two back-up copies on a regular basis: one to be stored in the cloud (remember to use a service that makes an automatic backup of your files) and one stored locally (portable hard drive, thumb drive, etc.). Disconnect these when you are done and store them separately from your computer. Your back-up copies will also come in handy should you accidentally delete a critical file or experience a hard drive failure.
> Use robust antivirus software to protect your system from ransomware. Always use the latest virus definition/database and do not switch off the ?heuristic? functions as these help the solution to catch samples of ransomware (and other type of malware) that have not yet been formally detected.
> Keep all the software on your computer up to date. When your operating system (OS) or applications release a new version, install it. If the software you use offers the option of automatic updating, enable it.
> Trust no one. Literally. Any account can be compromised and malicious links can be sent from the accounts of friends on social media, colleagues or an online gaming <https://blog.kaspersky.com/teslacrypt-20-ransomware/9314/> partner. Never open attachments in emails from someone you don?t know. Similarly, don?t open attachments in emails from somebody you know but from whom you would not expect to receive such as message. Cybercriminals often distribute fake email messages that look very much like email notifications from an online store, a bank, the police, a court or a tax collection agency, luring recipients into clicking on a malicious link and releasing the malware into their system. If in doubt, call the sender at a trusted phone number to confirm the legitimacy of the message received.
> Enable the ?Show file extensions? option in the Windows settings on your computer. This will make it much easier to spot potentially malicious files. Stay away from file extensions like ?.exe?, ?.com?, ?.vbs? or ?.scr?. Cybercriminals can use several extensions to disguise a malicious file as a video, photo, or document (like hot-chics.avi.exe or report.doc.scr).
> If you discover a rogue or unknown process on your machine, disconnect it immediately from the internet or other network connections (such as home Wi-Fi) ? this will prevent the infection from spreading.
