Limited connectivity help?

[Dylan]

So, my computer ha recently been unable to access the internet recently, and whenever I try, it says limited connectivity. I have tried restarting my computer, router, and starting my computer in safe mode with networking. IDK if this has anything to do with it but shortly before it happened, my computer wanted me to verify my windows program, and punch in my product key, and thats around when the problems started happening. Also, when i looked at drvices and printers on the control panel, the wAs a yellow triangle with an exclamation point on my computer. I ran a troubleshoot but nothing came up. Please help if you can and thank you.

Sounds like you caught a virus or spyware. Try restoring your computer to an earlier restore point, from Safe Mode.
