Why did my IP address change?

Why did my IP address change without my permission? Yesterday I acquired a back-door virus when I click on a link from Facebook that sent Microsoft Security Essentials through the roof. I scanned my computer with the program Malwarebytes' Ante-Malware and erased 6 files. Then I restarted my computer. I had to uninstall Essentials to reinstall it. Then I check my IP address and wasn't the same as before. Should I be worried? Can you help me?

Unless you get s Static IP from your ISP your IP addresses will time out and rotate. Unless you talking about your Private IP. Which IP are you talking about the on on your Router or the one on your workstation. If it is the latter then it is probably because you have your Network Card set to Automatic which will cause the IP address to change from time to time depending on how you have DHCP setup on your router.

No, I'm sure it's the IP address on my workstation. I don't have a router. I use a USB internet chip from Cricket. But to make things clearer The last three digits of my IP address changed from (xx.xxx.xxx.123) to (xx.xxx.xxx.115). and just now when I signed on I checked it again and it was xx.xxx.xxx.14. My computer seems to be running just fine. Is it serious? In kind regards - Mark
