Every once in a while, everything just stops. Pages don't load, etc. When it happens, all three browsers are affected; SeaMonkey, Opera and IE9. Also affects GoogleEarth, yet I can ping that by DNS. And all PCs on the LAN are affected.

I can still ping however, by either DNS or IP.

The only way I've found to restore browsing is to reboot the DSL modem.

Do you use an email client? In this state can you send/receive mail?

Keep in mind there is no comparison to web browsing and ping. Ping doesn't use TCP.

 

[wilbur_the_goose]

My initial hunch is malware. Try turning off each computer. Boot one up. Any change?

Have you run the Windows Malicious Software Removal Tool lately? http://www.microsoft.com/security/pc-security/malware-removal.aspx

The more I think of it, the more I wonder if your PCs are part of a botnet. The above removal tool should help. Also run complete anti-virus scans with an up-to-date A/V signature file.

Java has also been exploited. If nothing else works, try de-installing Java and see if you have any improvement.

(PS - I do Information Security for a living).

 

[SayWhat?]

Probably not in the sense that you're asking. eMail is all browser based. I'm not sure if Opera's mail client would qualify or not.

I'm trying the new Outlook.com, but I do not have the old Outlook client installed.

Why would rebooting his dsl modem correct the issue at that point? I know malware has changed the dns settings on them before but that's not what's happening here.

Also, are these all wireless, wired or a combination?

Do you have a talent or something that has the same issue? Couldn't remember of you had one or not.

 

[SayWhat?]

MSRT has been run, nearly monthly.
Malwarebytes is clean.
MSE is clean

PCs are wired.
DNS settings are unchanged as far as I can tell. They do revert to default when the ISP pushes an update, but when I notice it, I change to some Open DNS servers, picking servers at random.

Do you have a talent or something that has the same issue? Que?

 

[Shades228]

Clear your cache but ultimately it sounds like you might be experiencing the sign of a dying modem/router. Does it impact all devices? Such as a smartphone that can use a browser, tablet, or something like that?

Check for UDP and make sure it doesn't have some weird option or setting in the router. Make sure you didn't update something or install a firewall.

Yikes, didn't notice the "autocorrect". I meant to say tablet.

Why not set up an e-mail client for testing? Opera can do POP and smtp as well as mail via browser, but a simple mail client is easiest to test with. Just be sure to check "leave all mail on server".

 

[heathramos]

can you telnet to port 80 to a website?

telnet yahoo.com 80 for example.

pinging and dns lookups use different ports than opening a website

 

[dpeters11]

Pinging doesn't use any port, doesn't know about them.

 

[heathramos]

true...uses icmp protocol

I have had similar problems when I make changes to my router and have to reboot both my router and modem to get it working again.

maybe the router (or modem/router combo) has a firmware update?

 

[wilbur_the_goose]

dpeters11 - I didn't want the router rebooted. I wanted all the PCs shut down, and to start one PC back up. See if a single PC has the issue by itself.

Just a hunch, but a botnet sending spam would slow down a computer and its connectivity, especially on slow DSL. By having only one PC active, you would, in theory, reduce the outgoing spam by 2/3.

I can't run Chrome, all other browsers seem fine. Ran that malicious software from your link and it showed no malware. Got any other suggestions?

I really prefer Chrome and this is really annoying. Pages don't load, the home page locks up every time I try to use it and things like that. Any help would be appreciated, I'm stumped. I've tried suggestions from other forums, but nothing has cured this problem. I'm running a Lenovo G770 laptop, i5 System 7 with 8GBs of RAM.

[wilbur_the_goose]

Rich - did you turn off all but one PC?

Are you wired or wireless? If you're wireless, try running wired, and see how that works. Try taking your PC to a public wi-fi hotspot (Wegmans, Starbucks, etc) - does your PC work there?

What anti-virus software are you running?

PS - Your PC has plenty of power - that's definitely not it.

Yup.

I was staying in a condo on the beach a couple weeks ago and they had Wi-Fi and it worked well. I'll try it on a wire in a bit. I've never had it on a wire.

What anti-virus software are you running?

Norton 360

PS - Your PC has plenty of power - that's definitely not it.

Didn't think that was the problem, just info I thought you could use.

Though a long time Avast user, I've been settting up friends, family and client with MSE (MS Security Essentials) with very good luck.

Dump Norton, and any other anti-virus/malware protection as soon as you can. IF you can...

Did everything you suggested and it appears that my son's computer is the problem with my homepage being locked up.

The pages are loading as they should, but when I go to my homepage it freezes up.

Now my homepage is working correctly. What the hell is going on? Chrome is working as it should. How???

FYI...we use Microsoft Anti-Virus at work (business version) and viruses that end up in the java cache don't get picked up by Real-Time Protection but do get detected from the full scan.

it would be a good idea to schedule full scans periodically.
