computers are online but cannot open page

[tpadowner]

I am remotely accessing a wired network of 4 XP Pro computers online without any problem but none of the computers can access a web page either through IE or Firefox. It happened yesterday afternoon to all machines.

* The modem, router (Linksys WRT160Nv3) and all computers have been restarted
* cleared the cache, etc.
* I have run AV scan - clean
* run Malwarebytes - clean
* I can ping anything successfully from a C:\ prompt
* as indicated in other posts here and elsewhere, IE 8 while installed has not recently been installed

I ran Network diagnostics and looked at the log file. I have included it here for reference

If you can, download hijackthis from another computer, copy it to your computer, do a system scan, and post the results on here.

What anti-virus security program are you using?
Have you tried removing it (them) using add remove programs (programs and features)?

I resolved the issue last night by doing a factory reset on the modem and router.

The router lost the IP addresses for each computer.

The systems are clean of any malicious items

Thanks

Glad you got it cleaned, and I honestly was not expecting malware on it. I have been seeing an odd thing happening lately on a lot of machines. A proxy server has been showing up on various machines lately, usually without infections. So that was my thinking behind hijackthis lol.
