error sending request: server name/address could not be resolved

[rrroz]

I'm having an issue with my home desktop so I registered on Spybot today from my work laptop. I saved the download file on a memory stick to run it on my desktop. I was told by my ISP to run V1.6.0 and it will search and destroy any spyware however when I try I get:

Error sending request:
The server name or address could not be resolved.

It is on the updallocator.php (1 of 1) file....

My initial problem is that I cannot connect to the internet although my ISP says I have a connection and my modem is working; we reset the modem and browser together. My MSN and YM both work. IE went down first, then a week later Firefox.... I now have NO internet connection whatsoever.

After turning off the Firewall I still cannot connect so it was suggested that I may have a virus or spyware.

How do I troubleshoot this? I cannot even run this spyware program! Please help me, somebody?
