Effective and immediate virus removal.
How often do you check if your computer is infected? Rarely? Never? It’s time to change it!
I recommend the highly effective proven Malwarebytes application designed for Microsoft Windows, Mac, Android, Chromebook. There are two versions for home and company use. Malwarebytes effectively locates and removes malicious software (viruses, worms, Trojans, rootkits, dialers, spyware).

Virus removal is very simple and effective, limited to a few clicks.

Free and effective open source disk encryption software for Windows, Mac OSX and Linux.
VeraCrypt is a free and effective open source disk encryption software for Windows, Mac OSX and Linux.
I recommend VeraCrypt, it is an advanced data encryption application, based on the popular TrueCrypt (currently it is not recommended to use TrueCrypt). VeraCrypt differs significantly from TrueCrypt, the level of encrypted data security has been increased to a large extent.
VeraCrypt can encrypt entire disks, partitions, folders and portable disks, USB memory stick, you can also create virtual encrypted disks (also hidden). Encryption in VeraCrypt is done using very strong algorithms.

The free VeraCrypt encryption program can be downloaded at:

Use strong access passwords
Who doesn’t use passwords today? Email, bank account, social media.
The computing power of computers increases, so it’s important to create strong passwords.
Use a minimum of 10 – 12 characters to create a strong password. Uppercase and lowercase letters, special characters and numbers.
