Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

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.
