Windows 7: Two computers, same network, same IP?

joecrash · 15 Aug 2011

I am using Windows 7 HP, with a broadband connection, on an Intel i3 quad core, and a DLIINK router.

I was browsing the internet, when all of a sudden it stopped (browser=Chrome) loading pages, and a pop up appeared saying there was an error, and 2 computers on my network were sharing the same IP address.

I don't have 2 pc's, just the one, and don't understand how this could happen. I did have a virus last week - Trojan.ADH.2 but do not know if that is related to this problem.

I closed my browser, and opened a cmd line and typed ipconfig /renew, then restarted my computer, and since then I have not had any problems I am aware of.

Does this mean I have a virus or mal/spy ware on my PC?

Kaspersky Virus Removal Tool 2011
is a free software intended to disinfect infected computers, removing viruses, Trojans, and spyware, as well as any other types of malware. Kaspersky Virus Removal Tool 2011 uses the same highly efficient algorithms for detecting malware as Kaspersky Anti-Virus. Algorithms include a full-functional anti-virus scanner, technologies developed for detecting vulnerabilities in installed applications and operating systems, and a technology for running scripts intended for removing complex and compound viruses. The utility can be used as a free anti-virus software.

Kaspersky Virus Removal Tool 2011 is not intended for real-time protection of computer. After the disinfection of the computer is complete, the application should be uninstalled from the hard drive and replaced with the real-time protection anti-virus:

I'm sorry - I guess I should have listed the steps I have already taken so steps are not duplicated. I have run Kaspersky's online scanner, as well as their root kit scanner, but they came up clean.
I have also run complete scans with Norton, and Malwarebytes. These also did not detect anything.

Another question I would like to hear the answer to is: Can I disable the internet adapters such as the wan *.* adapters? I did disable the 6to4 adapter, but only because I used the netsh command to turn off Ipv6.

If you could open command prompt, and give us the output of an "ipconfig /all" (no quotes) then we could probably tell you which ones are safe to disable.

I think it's unlikely that your computer was infected by malware if you were showing duplicate IP's, (not that running a good scan with the Kapersky tool is a bad idea).

However... one thing I do wonder, do you connect to your router (if you have a router) wirelessly? If so, what sort of security do you have setup on the router? It's possible that someone was trying to hack your wireless network, and spoofed your MAC address, which would result in them being given your IP.
