Can't connect to internet/Can't find server

One computer can, one can't on same router

[Seoladair]

I have a cable modem and a LinkSys router. Two computers are plugged into the router.

One computer can't connect to the internet. Web browsers come back with "Can't find server" errors. Yet other computer can get through with no problem.

Now, the 1st computer did have a problem with being bombarded by spyware, adware, and pop-ups whenever a browser was opened. Installed 'SpyBot: Search & Destroy.' This cleaned things out. Rebooted, opened a browser, and got bombarded again. Ran SpyBot again and cleaned system out (some were same programs removed earlier. Installed Norton Anti-Virus, found 15, repaired 13. Last two were download trojans. System is running really slow and now it can't connect to the server.

2nd computer already had ZoneAlarm, NAV, and SpyBot and hasn't had any problems. This one can still connect to the internet.

I've tried rebooting the router, removing the network card and re-inserting it(after a computer reboot), and even trying a dial-up modem. Still no connection. 1st computer has WinME and is an eMachine.

Please Help.

This is almost like the worm that was around last fall - whatever it was called.... wouldn't let you connect to get the fix to remove it....

Was that the blaster worm? Senior moment + blond moment = approaching senility I guess!

I kind of had that problem a while back, one was fine but the other wouldn't connect to any websites, but port 80 was the only thing that wouldn't work...IM, pop3, ftp all worked though.

Can you ping your router? 192.168.1.1
or ping your modem? 192.168.100.1

I'm certain it was the scumware. Certain Hellbound programmers have figured out how to tie their software in with Winsock, so that if you try to uninstall it the Internet connection will stop working. This happened to me and what I eventually did was:
(a) undelete it temporarily (helps if you're using a tool that allows you to do that, such as AdAware)
(b) scan the Web for a more specific set of instructions for removing that particular product

At least by re-enabling infections one by one, you have a good chance of figuring out which specific infection is causing problems.
