I use Avast in two of my computers at the shop and every now and then something pops up from avast and it says my privacy is LOW and i should enable this avast SecureLine vpn. If anyone knows anything about this please let me know. It says it makes you invisible while surfing and encrypts your online surfing and never logs your internet activity. Let me know what you computer professionals think. I do have customer information on my office computers so i want them secure.
