Made changes up to 7, which may affect the building of the system and take important updates. What trapilosya and how iz tsim fight.
At the beginning of 2018, the researchers revealed two main differences between processors – Meltdown and Specter. In order to often solve these problems, Microsoft released an update through Windows Update.
However, there are many who appeared insane with these updates, which caused the computers of the coristuvachs to crash. Through Windows Update it is no longer possible to install a new patch, as the antivirus compiler does not install the registry key, which confirms that the software is safe for updates. The problem is that you don't have antivirus installed, the patch won't install, it's possible to check if the antivirus is present. As soon as Windows 8.1 is introduced to Windows Defender, then for Windows 7 it will be possible to find an antivirus, as if it had already updated the system.

On May 12, around 13:00, the expansion of the Wana Decryptor virus began. Practically for a few years tens of thousands of computers all over the world were infected. So far, over 45,000 computer infections have been confirmed.
Over 40,000 evils in 74 lands - Internet hacks in the whole world became evidence of the largest cyberattack in the history. The list of victims has not only a few people, but also the servers of banks, telecommunications companies and law enforcement agencies.
The Wanna Cry infection with the ransomware virus has recognized computers as the most important cores, as well as working computers in various organizations, including the MVS of Russia. Unfortunately, at the same time there is no way to decrypt WNCRY files, or you can try to restore encrypted files using such programs as ShadowExplorer and PhotoRec.

There is a Trojan vimagach WCry (WannaCry or WannaCryptor). We encrypt information on a computer and pay a fee from the decryption of 300 or 600 dollars bitcoin for decryption.
Also, on the forums and in social media about the infection, they talk about the signs of infection:
Epidemic of the WannaCry encoder: how to kill, how to kill the infection. Pokrokov ceramics
On the evening of 12 May, a large-scale attack by the WannaCryptor (WannaCry) zdirnik was revealed, which encrypts all data on PCs and laptops under Windows OS encryption. The fee for decrypting the program is 300 dollars from bitcoins (about 17,000 rubles).
The main blow fell on the Russian koristuvachs of that company. To date, WannaCry has reached an astonishing 57,000 computers, including corporate MBC, RH and Megafon. Oschadbank and the Ministry of Health also spoke about attacks on their systems.
Rozpovidaemo, scho directly at the same time required to robit, sob to get rid of the infection.
1. The encoder exploits Microsoft's volatility in January 2017. To minimize the threat, you need to update your version of Windows in the term:
Start - All programs - Windows Update - Check for updates - Get and install
2. Remember that the system was not updated and WannaCry wasted on the computer - both corporate and home solutions ESET NOD32 successfully detects and blocks all modifications.
5. To detect yet unknown threats, our products use behavioral, heuristic technologies. Like a virus, like a virus - nayimovirnіshe, tse virus. So, the gloomy ESET LiveGrid system successfully defeated the attack from 12 May, even before the signature bases were updated.
What is the correct name for the Wana Decryptor, WanaCrypt0r, Wanna Cry and Wana Decrypt0r virus?
From the moment of the first manifestation of the virus in the merezhі, there was already a lot of different information about the virus of the cipher suite and it is often called by different names. It happened for a number of reasons. Before Tim, as Wana Decrypt0r virus itself appeared, it was a first version Wanna Decrypt0r. This first option is not gaining such wide popularity, like Yogo's younger brother, but zavdyaki tsyom, in some novelties, the new encryption virus is named after Yogo's older brother, and Wanna Cry itself, Wanna Decryptor.
But all the same, the main names are Wana Decrypt0r If you want more koristuvachiv to replace the number “0”, type the letter “o” to bring us to the name. Wana Decryptor or WanaDecryptor.
І rest іm'yam, nіd yakim is often called the whole encryptor virus - tse WNCRY virus, so that the extension is added to the name of the files that the encryption was recognized.
In order to minimize the risk of getting the Wanna CR virus on the computer of the Kaspersky Lab facsimile, it is recommended to install all possible Windows updates. On the right, in that the newly created program only affects those computers, as they work on this software.
Wanna Cry virus: How to expand
Previously, we guessed about the way to expand viruses in the article about safe behavior on the Internet, so nothing new.
Wanna Cry expands like this: A sheet of "non-sheltered" attachments will be sent to the mailbox screenshot - you can have a picture, a video, a song, or a replacement for the standard extension for these formats, an attachment to a file extension - exe. When such a file is launched, the “information” of the system is detected, and through the infl uence in OS Windows, a virus is entrapped, which encrypts the data of the koristuvach, about the russiantimes.com.
Wanna Cry virus: description of the virus
Wanna Cry (among the people, Yogo has already been nicknamed Vaughn the edge) is included in the category of cryptographic viruses (cryptoviruses), which, when it gets on a PC, encrypts the files with a cryptographic algorithm, so reading these files is not possible.
At the moment, there are some popular file extensions that support Wanna Cry encryption:
Popular Microsoft Office files (.xlsx, provided by therussiantimes.com.xls, .docx, .doc).
Archive and media files (.mp4, .mkv, .mp3, .wav, .swf, .mpeg, .avi, .mov, .mp4, .3gp, .mkv, .flv, .wma, .mid, .djvu, .png, .jpg, .jpeg, .iso, .zip, .rar).
WannaCry is a program called WanaCrypt0r 2.0, which attacks a turnkey PC on OC Windows. Program vikoristovu "dirka" in the system - Microsoft Security Bulletin MS17-010, the reason for which was earlier unknown. For deciphering the program, the “wikup” at the rozmіrі vіd 300 to 600 dollars. Before the speech, at the same time, over 42 thousand dollars went to the hackers' rahunki, for the tribute to The Guardian.
Jerela:
On April 12, 2017, information appeared about the streaming of the encryption virus under the name of WannaCry, which can be translated as “I want to cry.” Koristuvachіv z'appeared power updates Windows in the form of the WannaCry virus.
The virus on the computer screen looks like this:
WannaCry negative virus that encrypts everything
The virus encrypts all files on the computer and makes it possible to redeem Bitcoin for $300 or $600 to decrypt the computer. Computers in 150 countries of the world were infected, Russia suffered the most.
MegaFon, RZ, MVS, MOZ and other companies were stuck with the virus. Among those who suffered, and just koristuvachі Internet.
Before the virus, everyone is equal. Retail, perhaps, in those companies where the virus is spreading across all local borders in the middle of the organization and infecting as many computers as possible.
The WannaCry virus encrypts files on computers like Windows. In June 2017, Microsoft released the MS17-010 update for various versions of Windows XP, Vista, 7, 8, 10.
Look, if you, who have Windows automatically updated, are in a risky zone for a virus, the shards took the update off at the same time, and could yogo disappear. I do not presume to assert that it is so true.
Mal. 3. Notification of the hour of the installation of the update KB4012212
The update to KB4012212 after the installation caused a restart of the laptop, which I didn’t deserve, more I don’t know, what can I end up with, but where can I go to coristuvachev? Vtіm, rezavantazhennya passed normally. Otzhe, live calmly until the offensive viral attack, and there will be such attacks - doubt, unfortunately, not be brought.
Have some kind of vipadku, importantly mother, schob bluo zvіdki vіdnovlyuvaty operating system and its files.
Windows 8 update like WannaCry
For a laptop with licensed Windows 8, update KB 4012598 has been installed
