Ransomware virus infection which encrypts files the hard drives of computers has become a global problem.
In yesterday held the highest cyber attack with the type of virus. Called WannaCry or WannaCryptor, By the ESET virus affected tens of thousands of computers from countries over 100. From government institutions, to hospitals, mobile phone companies, companies providing electricity and natural gas, all reported huge losses and delays in providing services after damage of folders by encrypting ransomware virus.
We have already published an article in March 2015, about this type of virus and gave some tips about As can prevent the spread of PCs.
Think there is a method 100% sure, would be to deceive. From experience we say that over time, there was a measure / a software that provides security for a long-term system. We do not think they would like it. Always or security breaches occur, always interested companies producing anti-virus will be to have these breaches Safety. But this is another discussion, starting from the idea that 2015, when ransomware was still "pioneered," came to 2017 to a massive attack with this type of virus. How many dollars and euros will be invested in security software after this attack? ;-)
If you are "home user" and do not want to have such a "surprise" measures to prevented from infecting your computer with ransomware are simple.
Waiting can you say that first you must have a antivirus software updated (and with a license), and again Windows to be updated regularly. Not. In addition, you should pay attention to what sites you access, what links you open and especially what download attachments in e-mail computer.

Never enter your e-mail never download atasemente automatic email server. Do not open the links if you do not check before source sender. Find here some information on how to do this.
Another method of infection It is through websites that offer "premium software"Unlicensed or serial (license key). That called sites "cracks". Try as much as possible to install on your system only the programs that are really useful to you, and download them from the manufacturers' sites.
When installing a program "broken", besides being illegal, no one can guarantee that the hacker who has made the changes to run without license, has not made other changes to create "entries" into your PC.
Portals for adults are a source of infection greater than any other. Over 99.9% of these sites are full of malware / adware and require installation on PC to various executables suspect in exchange for viewing content. Avoid as much as possible these websites or search for them on the reliable 0.1% :)
