Hi all, Is there any program like adware that can disconnect our internet connection? Because yesterday I cant go online, even I want to access Router Admin. But my friend's pc can go online through the same router.
After I tried some solutions, but I still can't fix them. At last I decided to restore my system to previous day, then I can go online.
If you think its adware, then go through the normal adware removal steps... adaware, spybot, maybe do a housecall.trendmicro.com scan...
Sounds like another issue... adware wants you connection to the internet to upload its info. Viruses usually want your connection so they can spread, but this sounds like it could be a driver issue. Are you on XP? If you are, right click my computer, go to properties, find device manager and check out your network card driver. Then go to the control panel, find networking(sorry im not on xp right now, cant remember exactly), and see what it tells you. Sometimes disabling and enabling it can renew your connection, its worked for me in the past.

That might of been overkill... Guess its too late then.Quote:

Then maybe not overkill... that works too.Quote:
to previous day
Just out of curiosity, did you load any new software between experiencing the problem, and your last restore point..................if so what?
Sometimes these things happen because of conflicts, so it is useful to know of any potential culprits.
Cheers
Just acomment,
The statement is true and correct.. But..Quote:

The reality, throw a combination of poor code, Misrocoft, user's background progs and the phase of the moon into the equation.. and yes you will have problems connecting to various sites..
Note Also some Hijackers will want you to ONLY Visit their sites, but because of a problem during the installation of the HiJacker ALL sites get blocked..
Cure for next time.. "Take three Aspro's and see the doctor in the Morning.."
the pain killers are:
Spybot Search and destroy (Updated)
Adaware v6 (updated)
CWShredder (get the latest Version.. don't use last weeks version)
HiJackThis (save the Log - and give that to the Doctor)
And if you want a good "Home" remedy.. give "The Cleaner" a run in safemode
yep thats the nurses advice..
cheers
Just to add on that-
Running in safe mode /w networking will always help a diagnosis...
Most "The internet is broken" complaints I get around the dorms is because of mass adware, or viruses on the box... adware will maintain a connection, but when you throw mass amounts of programs into the mix, it will slow it to a halt, which can seem like a broken connection.
Adware and spybot haven't helped my hijacks in the past, so far Hijack This has been great, although its potential to screw stuff up is huge.
Yes. I did install(Trojan Remover but I remove it at the same day) and uninstall something also. I cant remember what program that I removed, because I just remove any unexpected program.Quote:

the truth is, it has nothing to do with any program installed. it is one of the recent attacks now on the net, i got hit too.
I have gotten hit to, but I have bounced back as always ;) . My problem was (and is likely your problem to) was due to a trojan/virus that alters your TCP/IP settings. This will "break your internet" lol. The best defense is an up to date AV protection or a system restore will did the trick, it did the trick for me.
hmm, now i had this problem. or so aol, seemed to think i had that problem...i kept getting a message that my connection wasn't secure and it couldn't be fixed with their autofix. so i said tell me how to do it, and i tried everything, and i couldn't get rid of the message, after a few tries, i then got an additional message that my system had just crashed ???, and ummm...i could (and of course aol couldn't either), seems to fix that. so once again, back to system restore......but i wasn't getting logged off, and my system didn't crash???? now its an attack on the web? man....and when i did my double checks and stuff, nothing, no bugs, no spam/ad-ware came up...... :confused:Quote:

did u check your system for viruses (trojans). try checking it out. might just be another case of d.o.s softwares (denial of service)
Maybe check your Modem driver.
Maybe you've somehow changed your Driver to be another one, and now your Computer cannot connect as it is not detecting the Modem?
Just a thought.
Did you try to Restore ur PC to early days? Maybe it could help if you did not find any solutions.
Hey hey,
I realize that John has already resolved this problem, but since this thread is still going I figured I'd clear up some fallacies, and give some pointers to others having the problem.
This comment is so far from the truth that it makes my head spin. It has everything to do with software installed. The software may have been installed unbeknownst to the user, but it is still do to software. The key player that comes to mind right now is VX2.ABetterInternet.Quote:

On any given day I will deal with 2 or 3 residence students who have lost their connections due to some sort of malware (I think that term is so much better than spyware and adware.. but anyways). It has come to the point where it isn't even worth our time to attempt to find the source of the problem (bad methodology if you want to learn, but it works well when you just need to solve the problem, get them out and see the next person.). Anyways we can usually tell in about 30-60 seconds if it's malware affecting the persons computer. They call down with their problem and the first thing we do is have them run ipconfig/winipcfg. If they have an IP address, yet can't ping anything... we assume malware. We're right about 98-99% of the time. Sometimes they have an IP and can ping, but they can't browse... again malware. Another scenerio is they have an MS Automatic Private IP address (169.) If this is the case it could be a cabling issue, so the next thing to do is have them check for link lights. If they have link lights... the assumption again is some sort of malware.
The student will then bring our PC to us, and we always follow the same path. Install Spybot S&D, update it and scan, next we install AdAware, update it and scan. Then depending on what I've found I may run CWShredder. After that we update their AV (if they have AVG or NAV), or uninstall it (if they have McAffee or eTrust) and install AVG. We also license eTrust, but we've found much better results with AVG. Several times we have scanned a machine with an up-to-date copy of McAffee or eTrust and then removed it and scanned with AVG and found several more virii. After the AV is installed/updated, we'll run a complete scan. After that we'll plug them into the network and usually they'll have a connection. If they don't theirs one last thing to do and that's to reset their TCP settings. There's a great utility to do this and I suggest if you ever lose your connection you make use of it, actually even if you notice your connection is slower than it normally is.. this is useful to run. Its Option^Explicit's WinsockFix (available here). It basically performs a net sh reset logfile (can't remmeber the complete syntax atm). I have a 3mbps DSL line and for a while I was lucky to hit 100K, I ran the WinsockFix and I was back up to full speeds.... so it's really handy for anyone.
Anyways, that's how we operate. Like i said it works about 98-99% of the time, possibly even a little higher, occasionally you'll have a PC with bad NIC, or an OS config problem... however that's rare, the primary cause of lost internet connections these days is malware.
Peace,
HT
i ran into the same problem when i was working for a computer repair shop. what happend was that the user installed adaware and found many spyware, mallware, ect. on his comp. he then removed it all.... after this his internet did not work any more....
i believe that the spesific kind of mallware alters your registry in such a way that your network connection could not be used ithout it.....
however this (like you said) can be undone by restoring your box to a preavious date...
thanks for that link HT, i know ive got use for that. just one question. in the file name WinsockXPFix does the XP stand for X-plicit or is this a version for WinXP?
Hey Hey,
That's an excellent question, we've got another one at work just called WinsockFix, and then we also have WinsockXPfix.exe. I'm not sure what the difference is.. the both run the same, we use the primarily on XP machines, however on occasion we've ran them on a 98 machine... just not sure if it has any real affect. I'll have to look into that.
Peace,
HT
Thanks all mate....
First time on this, pretty exciting looking, site.. ! :)
This subject first caught my eye, since it just happened to me a few days ago.
I got some additional info to what has already been said.
My computer was up and running fine. Downloaded the latest Critical Updates from Microsoft. (WinXP Pro) Rebooted, and now I can't browse anywhere! ICQ couldn't connect, MSN couldn't either, but PING did work!
I'm running Sygate Personal Firewall, that is supposed to show all programs that is using any kind of connection, but I couldn't find anything unusal in there.
Opened Task Mgr. and started End Task program after program. When I killed ICQ, it all started to work at once... if this was a coincident or not, I have no idea?! Maybe something has infected my ICQ program.. ?
So my question to all you who had this problem is, do you have ICQ as well?
Thanks!
HTRegz, your right, spyware/adware is mostly the cause for this kind of problem, but there is a trojan going around that alters your TCP/IP settings. I dont know if some of you AOers call that an "attack" but I do. The trojan is called Trojan.Qhosts, you can find more info about it here:
http://securityresponse.symantec.com...an.qhosts.html
It also has a removal tool on that page ;)
Hope this helps
friend of mine had the same prob, we linked it back to network card driver that was adversly affected from virii.... Had to reinstall everything but working now...
hijackthis,adaware,norton or mcaffee a must....
As I did, I restore my winXP to previous day.... to those who facing the same problem n want to reinstall everything, may be you can do as I did... ;) save alot of your time.
I'm using System Mechanic 4 Pro to eliminate spyware in my PC... I think it quite good utility.
Yes, I did the same thing, system restore, and it works. The problem is the trojan is still there, so I would suggest using the tool to get it out if you havent updated your AV already.
jus curious...who do you have for an internet provider? i've had only one "attempt" (or so Norton Internet Security 2004 Pro says) from an outside computer to TRY to access my system(not boasting jus curious)
Hes boasting,Boasting I tell ya....Woohoo go norton :cool: .Just kidding
