Will this product guarantee that you will not be hacked, I doubt it! but will it make the task of hacking your private / business information thousands of times more difficult than if you did not have this, this is like 2 cars side by side with the same specification, one has the top of the range alarm, the other does not, which one will be hacked! A slight concern due the size of the YubiKey 4 Nano there is a potential to lose, while they are options available should this happen.
You are seeing strange posts ‘made by you’ in your social feeds. Or maybe your ‘Friends’ are receiving inappropriate messages, allegedly from you.
Your friends are reporting receiving strange spam or emails from you. You could have been hacked!
Adopting a ‘Think before you Click’ mentality is the most valuable action you can take where you consider each email attachment or URL link and the sender it came from before potentially launching some malware on your Laptop / network
If you feel that your Windows PC may have been hijacked, you should disconnect from the Internet and boot into Safe Mode and run a full deep scan of your antivirus software. If your security software has been disabled, use a good on-demand antivirus scanner. and run it from an external disk or USB.
A great positive on this product, you purchase once with no annual subscription fee each year as you get with e.g. most antivirus. This is not a replacement for good up to date antivirus. If your considering two-factor authentication / preventing hacks certainly worth a look at YubiKey 4 Nano.
