For instance, banks, online shops and other sites that are working with private information need to ensure that user’s or customer’s data is safe and invisible for third-parties.

When browsing the web, you might find that different site addresses might start either with HTTP or HTTPS. The letter S stands for security; thus, the website has a DigiCert certificate. However, you should not think that sites with HTTP are not safe to browse.[3] It’s not true.

Actually, the majority of websites use it because they simply do not have to deal with private information and they don’t need to spend money on this certificate. However, if you browse through online shops and think about buying something, you should pay attention to the website address. If it does not have HTTPS, you should look for another retailer in order to protect your personal information. HTTPS uses data encryption to protect your data from third-parties or cybercriminals.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
