Privacy error on all browsers

[Billy_1]

I don't really know if this is the right area to post this, but i couldn't find a more suitable category.
So as the title says i am having trouble connecting to any website (minimum to none exceptions) with any browser (google chrome, ie, firefox).
Google Chrome states that it is a privacy error and at the bottom ERR_CERT_AUTHORITY_INVALID. The thing is that i am using windows 8.1 and there are 3 profiles on this pc, but this problem occurs only to me. I have tried using google chrome from my brother's profile and everything worked fine.
Please a little help would be just great because i couldn't find any solutions for it that work for me.
Thanks in advance!

As I know, it is certification error, install GeoTrust Global CA certificate
1. Go to IE browser - Internet options - content - Certificates -Intermediate certificate authorities
2. Click on Import and install that certificate
3. Click apply and OK
4. reopen the chrome or IE, it should open all the websites

I checked that, didn't work for me, but i found what was messing with my browsers. It was just a program we were using to limit my brother's time on the pc! Thanks anyway though
