Limewire and other P2P programs are notorious for installing spyware/malware or facilitating such. That is why I don't use them.
In SAFE MODE with system restore disabled:
* Scan for spyware with more than one antispyware program (use latest definition file).
* Scan for viruses (use latest definition file).
* Run WinsockXPFix.exe if you can't connect after disinfecting the computer.
All else fails, wipe HD and reinstall everything. Now, do you really want to use Limewire after all that?
I had a problem similar to this one on my desktop and my uncles. My Internet was working fine (DSL) but a propram to download music (Lime Wire) couldn't get Internet access because of the firewall in my PC so I whent to the firewall settings to allow Lime Wire Internet access again, it was working fine before as it does konw.
My uncle had the same problem with this Lime Wire program and I fixed it, he had Internet (DSL)for a while He lived in a different house when this happened and I think he had the same problem that he could't go on the Internet after.
Then he move to his new house and he has the same ISP (Verison) but with a different DSL modem and he still can't use the WWW. A friend brought his laptop to my uncles and the Internet works good. I connected the PC and laptop the same way with the RJ 45 cable.
Do you think the firewall is preventin the PC to use the WWW? the firewall is ''on''
