I've tried installing a free VPN "Windscribe" to watch wimbledon tennis streams from outside the UK: sadly the stream was chopped, so i uninstalled it using Comodo programs manager (with the hidden files too)
Then on most betting sites (with some exceptions) i always get  "Your connection isn't secure" with  "NET::ERR_CERT_AUTHORITY_INVALID" and "someone is trying to steal your details". In all browsers.

I've checked their SSL certificates, and they're all valid.


Though home banking and gmail are ok on all browsers too.


I of course know there are a million reasons to get this warning, and i checked them all.

So, just to be safe, i reinstalled all my windows 7 system from an image: but it didn't fix the warning.


So, am i paranoid, or do these free VPN install malware? It would have to be on my router, as i get the same warning from another computer connected to the router.

They just want to entice you with a free VPN, ultimately leading to their paid service for what you term as 'unchopped' content.


Nothing is for free today.....remember that, and you will be able to make the best choices!


I doubt very much that they promote malicious content, installed on remote systems........as a rule, they would be blacklisted very quickly!


Your warnings are most likely 'false positives' from your noisy (free) security software.

1) can you confirm that I understand this correctly: you reinstalled your Windows 7 machine and you still get the same errors?

2) what about other machines in your network, like PCs, tablets, phones, ...: do they show errors when you visit the same sites?

3) can you check the clock of your machine and confirm that the date is correct?

That could just be from the browser unless it mentions the Vpns or something like that in which case it may not be totally unistalled properly but this wouldnt keep happening after a reinstalll from a clean image.
Id say it might just be the your system trying to tell you to be very cautious which isnt really something to worry about although you'd be better off not going keeping from these sites in general.
