URL Lookup Paralysis - Malware or Something Else?
I've never encountered this before, or even heard of it. Let's get a bead on what's causing this so I can make the appropriate moves...
The symptom is very easy to describe: My trusty Win7 laptop (which I can't use to post this or sysinfo, unfortunately) works fine, but after going to several URLs loses the ability to connect to any more until I reboot the system, at which point I can look up a few pages and then experience lookup paralysis again and the browser times out trying to connect to the URL. This is the case with ALL of the URLs I try including Google, Yahoo, etc., ones that are obviously not experiencing server problems.
This is the case with either Firefox (current update) or IE.
Everything else seems to be 100% OK on the laptop. I don't experience this problem on other computers.
I updated Comodo and Malwarebytes and ran the deepest, fullest scans with both, but no problems were detected. This really smells like a malware problem to me, but these programs say no.
Can someone give me an idea where this strange problem is coming from?
Thanks!

I'll check again, but I think it's about half-empty.How full is the hard drive?
Do you have an hp laptop?
Do you use any other browsers?
And exactly what versions of Firefox and I.E.?
Do you get any specific errors?
Vague memory of driver for network adaptors, and need for a re-install.

No. It's a Gateway NV53.Do you have an hp laptop?
None other than these two are installed.Do you use any other browsers?
Firefox 53.0.3, the latest. Cannot upgrade IE for some reason, as Microsoft says it won't work on my machine, but I doubt this makes any difference. The problem occurs with either browser, updated or not.And exactly what versions of Firefox and I.E.?
No errors. sfc /scannow shows "no violations" in the system files.Do you get any specific errors?
I don't follow.Vague memory of driver for network adaptors, and need for a re-install.
HD has ~375G of free space. I cleaned up the registry with CCleaner. No change.
Everything works fine otherwise. I still have an instinctive feeling this is some kind of malware that my scans aren't seeing.
Try to upgrade and/ or downgrade network drivers for your wifi or Ethernet.
Is this an AMD processor or CPU?
** On edit - Seem to recall that HP and Gateway with AMD processors had same problem with url's dropping out. Believe the fix was mentioned here 3-4 years back.
I almost remember a dos level command required refresh with my old POC Gateway NV 53? something, if I can find it. With a refresh of drivers.
Forgot I.E. is no longer supported on Windows 7, admit I've been lulled back to Lenovo and Thinkpads.

OK, here's the latest...
I've tried this with a different USB WiFi dongle and it changes nothing, so it's not the internal WiFi or its drivers. Yes, it has an AMD CPU.

I have to say that this is one of the strangest computer problems I've ever had.
OK, the above solution did nothing, but in desperation I did a rollback to a system restore point from a couple of months ago. It created a few other problems, but the one to which we're referring in this thread cleared.
So...in a goofy way, I guess we can call this "solved."
[LATER] Nope, after working fine last night, it's started up again.
I'm restoring it to an earlier restore point from March and will see what happens.
[Sigh!]

What security suite (or other anti-malware program) is, or ever was, on the system?
Comodo, very laboriously removed and reinstalled. Going to previous restore points really screwed that up, too.What security suite (or other anti-malware program) is, or ever was, on the system?
Nothing (0) has changed with the problem.
I've never seen anything like this before.
I've never HEARD of anything like this before.
Ridding a computer of Comodo and cleaning up after it appears to be a real mess. Maybe this procedure will help: https://forums.comodo.com/install-s...nstall-cis-to-avoidfix-problems-t58620.0.html
Do not reinstall it until you've run the Stack reset (post # 8) again and then tested to see if the issue has improved.

This is such an incredibly strange problem, I am not sure where to put this, but let's try here to start. If it needs to be moved, the mods can feel free to do so.
An earlier attempt to diagnose this petered out into nothing and was closed. See thread here and check to see if your suggestions have already been tried without success.

I got back on it tonight and got a little more information (which only makes the problem more mysterious, not less), but the problem remains... OK, here goes:
My laptop seems to be working perfectly. I connect to the Internet and a page or two load properly.
At this point, I notice a decelerating slowdown in further pageloads until page loading completely stops or is reduced to dialup-level speeds.
Other computer functions seem to work fine. I just can't load any more pages until I reboot...then the process begins exactly the same way.
* This happens with any browser
* This happens with internal WiFi, external WiFi or cable LAN connection
* Other computers on my home system show no problem
* Previous suggestions (see linked thread, above) made no apparent difference
* Thorough scans with Comodo and MalwareBytes show the system clean
* Restoring the system to a previous restore point made no difference
* This problem still exists on other Internet accounts, like at the library
Now, here's the REALLY strange new discovery I made tonight. Try to stay with me on this one:
I got online via LAN connection and tried a few sites before the web locked up on me. One of the sites was the Ookla speed test site, which ground to a halt before the test could be run. However, it was the most recent site in the "History" cue, so after I rebooted, I went into Firefox and brought that page up from the History menu as the first site. As the first site on a new boot, it loaded and I could run the speed test.
The down/up speeds were exactly what they were supposed to be, a little better than 15M down and 1.5 M up.
OK, so I keep the test page on the first browser tab and open a new tab to do further browsing. As expected, the subsequent sites eventually ground to a total halt, or very nearly.
BUT...when I switched back to the first tab that had the speed test page loaded I clicked on the "New Test" button to see what had happened and discovered that the throughput was still testing perfect, even with webpage loading virtually paralyzed! I retried it several times with the same results. Throughput is fine!
What?
Can someone PLEASE tell me how to fix this weirdness?
Many thanks for any remedy.

You have not yet responded to my post # 13.An earlier attempt to diagnose this petered out into nothing
Short answer: At the time of the post, I spent an entire afternoon going through that tsuris and doing a fresh reinstall of Comodo 10. It had no effect at all. Apparently I didn't report back on that.You have not yet responded to my post # 13.
BUT...I just now went in and did Comodo's online uninstall of their latest update on my box and re-accessed the web and accessed sites with no protection and everything once again worked perfectly, with no loading delays or choking out. My computer loaded sites faster than I have remembered it doing, ever.
Conclusion: THIS IS A PROBLEM WITH COMODO: NO COMODO, NO PROBLEM. Unfortunately, there's also no protection on my computer.
Apparently, re-installing Comodo will surely bring back the problem, as it did back when I did this before.
Now what, I wonder?
If you want protection and performance with Windows 7 use the built-in firewall and Microsoft Security Essentials.
