This is when a vulnerability is used to access or infect a computer. Zero-day exploits are those that are used before a software vendor is made aware of the vulnerability. When the vulnerability is identified, software vendors release a patch to fix the vulnerability, which renders the exploit useless. This is why it is important to install software updates recommended by your operating system and programs that you use.

TrustpilotOld Chromebook With Outdated Virus Protection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 The C-Book works fine, but I was hesitant to use it due to outdated protection.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.
