Uses encryption to lock users out of their computer or hold some data hostage until some form of ransom demanded by the attacker is met. It is a form of malware that denies a user access to their files, accounts, or computer until they’ve paid the ransom. After the ransom is paid, there is no guarantee that the user will be granted access to their locked files, accounts, or computer.

Old Chromebook With Outdated Virus Protection

I have an older model Chromebook with built-in virus protection that Google no longer updates. The C-Book works fine, but I was hesitant to use it due to outdated protection. I also didn't want to buy a new model since mine still works quite well. Guardio to the rescue! Thank you for a good product.

It works very well ... I like it no telling how many times they have saved my computer from crash and burn and it also alerts you of suspicious sites ... love it and it is reasonably priced.
