It may look completely legitimate since scammers tend to intimidate victims by claiming that it may lead to data loss, identity theft, loss of passwords for social networking platforms and credit card details. The developers urge to contact “Microsoft Network Security Advisor” via toll-free +1 844 699 8351 number.

You should be aware that fake warnings are created to collect victims’ mobile numbers and later, offer their “help” to fix the nonexistent problem. Cybercriminals might choose between several ways to swindle money:

  1. Insist on purchasing sponsored or expensive security software that is unnecessary for you;
  2. Ask to provide access to manage your computer remotely and infect it with high-risk computer infections to continuously charge money for their services;
  3. Distribute malware through spam text messages.

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
