Help! deleted virus and lost internet!

Hello,
i used a squared free and it found a high priority virus in my computer (i have a laptop and a pc, this happened to both of them) and it sait it could not be deleted, but i thought it was just the virus manipulating my computer, so i waited a min and it let me quarintine it after a while, and then i deleted it, and then it's where things went wrong, about that time, my computer lost connection to the internet, and it said "limited or no connectivity" and then i tried to repair it and it said it was getting new ip settings, but it fails every time and im completely lost and it's like that with both computers... i dont know what to do, please help me, i really need my internet, what should i do?
