First of all, hello to the BleepingComputer community. I have been to this site before to find answers to problems, but I never had one so bad that I felt the need to create a topic. Here we go:
I'm using Windows XP Service Pack 3. I'm on a desktop computer with a wired connection. The computer has a Trojan tracur virus that Malwarebytes cannot remove. Every time I run the scan, it pops back up and this is what it says:
Registry Keys detected: 1
So I decided to install Ccleaner and run a scan. (I know, I know).
I clicked on "Cleaner" not "Registry" on Ccleaner. It removed over 400 MB. I thought that the "Cleaner" scan was relatively safe. But when I tried to get on the internet afterwards, it kept saying "Unable to renew ip address", "Unable to contact DHCP server". When I do ipconfig/all, my default gateway is missing and the ip address and dns servers start with "fe80".
ipconfig /release, ipconfig /renew,
I went to Network connections and made sure that "Obtain an IP address automatically" and "Obtain DNS server address automatically" were checked.
I have reset Winsock and reset TCP/IP.
I went under "Services" and everything was automatic and started.
I'm on a wireless network and the other computers work fine, but the desktop computer cant log on to the internet. I'm at a loss, and I don't know what needs to be done to reestablish a connection. Any and all help would be appreciated.
