Solved Slow internet, virus scan clean, what next?

July 30, 2011 at 12:40:16
Specs: Windows 7, 148
Within the past week my home laptop is loading veeeerrrrrrrryyyyy slowly on the (wireless) internet. We have run 3 "deep" virus scans (AVG, Bitdefender, Avast) with no virus found. We are not gamers or heavy users, just news and information searches, mostly. A little help with diagnosing the issue would be appreciated!

Hi ??? - your last post suggests you have cured the fault.

Great news!

Further thoughts:-

Because of the complexity of modern systems, on occasions it is wise to power off completely, then after a few seconds (not immediately) power on. This perfoms a cold boot, loading its operating system 'fresh'. Often forgotten is one's mobile phone which can benefit from this procedure - mine does.

Freebie internet protection programs are never as good as those purchased.
e.g. I use Norton Internet Security 2006 which supports my w2000 os, whereas nis 2007 does not.

There seems to be two majors in this field, Norton and Mcavee. Shopping around (ebay) one can find last years or earlier at knock down prices. Must be unused though. They offer a years protection including virus updates etc. Thus every year I purchase another new one (from ebay).

Statistics can help with such problems.
Google is your friend, e.g. try:- 'w7 wifi statistics'

An example of statistics usage:-
My desktop pc is old and about 2 feet from the router. The wifi was an add-on using a bluetooth usb dongle. The program that came with the dongle provided statistics which showed 100% connection strength, yet a huge (and I mean HUGE!) failure rate on downloaded packets. These were having to repeat in order to be successfully received.

Was advised being too close was the probable cause. It made sense anyway to use a direct connnection as this port was twice as fast as the wifi one, plus not running wifi reduced the load on my pc.

At times there are two other laptops (plus sometimes a ps3) all connected by wifi to my router. One laptop is watching Italian tv almost constantly. Speed is very good (my isp is TalkTalk) on my upto 8mb connection. TT hope to be upgrading to upto 24mb, giving 17mb usable in the near future.

Using speedtest is interesting, because it recommends the best server for the test, AT THAT TIME.
However this can be over-ridden. Thus sometimes I compare my 'near London' results, to one in Naples Italy (where my wife is from), and then Sydney. The distances involved make quite a difference.

Regards - Mike

Try restore point.

Do a checkdisk on drives.

Check taskman for clues, See if memory shows what it should be or test it.

If you have stubborn rootkit or simple data errors it may need a clean reload from OEM disks.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Thank you for responding so fast! I'm running PC Matic (PC Pitstop) right now. I'll be interested to see what it comes up with. This is a pretty new computer, but I noticed that the PC Matic took longer on the "driver" section of it's testing, so that could be part of the problem. I'll chime back in when its finished.

Hi Worthitall.

Please clarify what you mean by 'loading'.

At what stage does it appear slow.

Here in the UK, TalkTalk recommended me speedtest.net as a good internet connection speed tester. Which it is.

Ideally for testing, a direct connection is required, but it works with wifi as well.

Good Luck - Keep us posted.

Thanks, Mike.

By "loading" I mean that when I go to website it can take *minutes* to open up the page. I can see the progress indicators, for example right now there is a little message at the bottom of this page indicating "transferring data from kona.kontera.com", so the various ads and links are still loading.

I ran AVG again yesterday and it found a rootkit, which it cleaned out. That seemed to help some. I also found an "internet optimizer tool" that was able to refine some of my settings. I also turned off a bunch of unnecessary auto-startup programs. I doubt that they were hampering my internet, but at least I'm able to function online. That has been a problem for the past week.

As I type this I have also been trying to open speedtest.net, but it has not yet opened to the point of being useable (dark background screen, no testing links). waiting.....waiting.....

BTW, we have another computer with a direct connection that we use for streaming video to our TV. My husband runs speedtest on it regularly and we get about 20mps download, so its not likely to be our internet connection. Speedtest is still not loaded on this connection...it has been about 10 minutes.

Other sites have opened up within 15 seconds or so this morning. Still really slow, but at least I can see what I need to see. I don't know why speedtest is taking forever...oooh - now it has a white square screen in the center of the dark background. "transferring data from cspeed.net". Maybe it will be useable soon!

In the meanwhile, I ran AVG rootkit scan again, and the rootkit from yesterday is back. The AVG message says "Inlinke hook ntkrnlpa.exe NtQueryInformationProcess+0x1C29 -> 0xE6D33E22" "Corrupted section ntkrnlpa.exe[PAGE] NtOpenThreadTokenEx+0x3DE, size 4 bytes".

Speedtest is still not up and running. I'll submit this and follow up with the test results if I ever get them.

Thank you for your help! As you can tell, I really need it! :-)

go here:
http://ftp.ch.debian.org/mirror/pcl...

download this and create a bootable cd:
pclinuxos-lxde-mini-2011.06.iso

boot from the cd, get to the desktop, open firefox and test.
post back

also, when you boot the cd, use the arrow key to highlight and choose the "run from the ram" option.

Sometimes rebooting the wireless router can do wonders. Unplug the power cable from the router for about 5 seconds, then plug it back in.

Hi ??? - below is what I would try.

If you are connected with wifi, can you try connecting directly to see if speed improves.

Have you loaded taskmaster (cntrl +alt + delete) which might help as it shows which tasks are running at the time.

How close is your pc to the router?

Are you able to see your wifi statistics, to ascertain frames sent/received/failed.

Are you using Norton Internet Security - if so which?

THX1138's suggestion is good, even if your husband's is ok, because his is using a different port/connection method.

How much spare space is available on your hard disk?

Bear in mind linking to some sites can be slow, (whereas others are fast), possibly because the server might be hibernating or whatever and has to 'wake up'. Thereafter responses are much quicker.

If you have Firefox, there is an add-on or two that stop unwanted dross downloading such as popup adverts.

As a matter of interest, where are you based? I am in Hammermsith, West London.

Is the slowness constant, or after a while does speed improve to normal.

Regards - Mike.

Good luck. Keep us posted.

Okay. So I FINALLY was able to bring up speedtest.net. My upload speed is a break-neck .11 (that is not a typo). Download, .22.

I opened my taskmaster, and my CPU usage is only 17-20%. Physical memory 48%. I don't see any processes that look wrong, but I doubt I'd know just by looking.

The only thing I see that looks a little strange is the scvhost.exe is on the processes list 10 times - 3 as user name SYSTEM, 2 as NETWORK SYSTEM, and 5 as LOCAL SERVICE. All are showing memory usage, but the two Network System processes are using the most (58,308 and 14,640). The description of this process says "Host Process for Windows Services".

We hooked the laptop up directly, and the download speed immediate was up to 21mps. So, it looks like our wireless connection is the culprit. Do you know if that means we need a new wireless card? Or is there some other "fix" to check?

Plus, I still need to deal with that rootkit issue, because that can't be good.

Thank you for all of your helpful input, Mike. We are in Mount Dora, Florida, U.S. Just a quick drive from Disney World, to give you a little perspective. It's amazing that I am able to receive help from London. I love it!

I neglected to respond to a couple of Mike's questions:

I my laptop is typically used within 7 feet of the router.

I do not know how to review my wifi statistics. It would be interesting to see what is happening, though.

We do not use Norton. I have some Firefox add-ons that block ads and alert me to dangerous sites. We use AVG 2011 Free version for virus scanning and removal. I have also recently loaded Avast, as a secondary scan.

My computer has 148GB of memory, with 111GB free space. It is a fairly new computer.

Maybe some of that helps. Thank you again, Mike!

My husband didn't think we needed to re-boot the router, but I read him the answer above and he went ahead and shut it down. You guys are great.

21MPS WIRELESS!!!!! Woo Hoo!

Thank you! I love it when its simple.

That rootkit is still on my radar, though.

Thank you, Mike, for your very helpful input. We only usually have the two computers running (unless we have guests who bring computers with them, which happens from time-to-time). And the laptop is the only one with the wireless connection. We have cold-booted the router occasionally due to power failure or other internet interference (Florida has LOTS of lightening this time of year). We now know to try that if we are having slow connectivity with the laptop.

Regarding the rootkit-thing - As I search around for information, I'm seeing occasional reference to "false positive" rootkit readings of Windows 7 by the free virus screening software programs. We may have to spring for the money to pay for a screening program to accurately diagnose the issue.

At any rate, your help has been greatly appreciated! Thank you!

My most recent purchase of NIS was around £10 which covered 3 pc's.

Hope you are taking precautions when lightning is around.

I lost two pc's completely in Italy, that I had installed at relatives, by them not being fully disconnected, and suffered much damage to a tv here in the UK.

Lighting is a strange phenomenon, it can come in on any cable, pass through some fuses without blowing, damage some equipement, leaving others untouched.

Good Luck - Keep us posted

Florida is a very lightening-rich environment! Our homes are built with lightening protection as part of the building code. That is absolutely no guarantee against damage, merely a tiny bit of insulation. Unless we intend to unplug everything each time we leave a room unattended, there is little we can do beyond install good surge protection. That is what homeowner's insurance is for, I guess...

I have lived in Florida most of my life (older than I want to mention). I have known two people whose homes were stricken by lightening. One lost all of the electronics in their media room (lots of $$$); the other strike came in through a telephone line and blew out the phone system, but everything else was spared.

It's a fact of life... :-/
