I can;t get onto paypal as the error below keeps coming up! Has my computer got a virus??

You attempted to reach http://www.paypal.co.uk, but the server presented a certificate issued by an entity that is not trusted by your computer’s operating system. This may mean that the server has generated its own security credentials, which Chrome cannot rely on for identity information, or an attacker may be trying to intercept your communications.
You should not proceed, especially if you have never seen this warning before for this site.

Help needed please!

Hmmm… possibly malware.

Certificates are issued by trusted authorities, and your computer knows they are trusted authorities because it has a list of all the people who are allowed to issue them.

Either the list on your computer has become corrupted, or you are being redirected to a website that is not actually paypal and is run by some dodgy people – because they will not have access to a proper certificate issued by a proper authority (since it is easy to make your own certificates, but you will be your own authority and hence not one of the trusted ones).

Your computer could have malware which is waiting to redirect your browser to a dodgy site when you type in paypal.co.uk

Can you click on ‘more details’ or something on the error message and show us what the message says? Take a phone pic maybe?

It says this

http://www.paypal.com normally uses encryption (SSL) to protect your information. When Chrome tried to connect to http://www.paypal.com this time, http://www.paypal.com returned unusual and incorrect credentials. Either an attacker is trying to pretend to be http://www.paypal.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

Network errors and attacks are usually temporary, so this page will probably work later. You can also try switching to another network.

Technical details

http://www.paypal.com has asked Chrome to block any certificates with errors, but the certificate that Chrome received during this connection attempt has an error.

I googled HSTS failure, and got this:

Looks like there might be a problem with Kaspersky.

Is your clock / date / time zone correct?
