Internet Connectivity No Longer Works After Virus Infection
Mar 17, 2009
I'm running XP Home Edition. A few days back I contracted one of those viruses that hi-jacks IE, but I was able to catch it before it completely installed. I used Malwarebytes, AVG and SuperAntiVirus to get rid of it and (after several scans) I'm now pretty certain that my system is 100% clean.Nevertheless, under the one user account that was infected AND in Admin (Safe Mode), programs like IE, Firefox, and Rhapsody can no longer find an Internet connection. Also Malwarebytes and SuperAntiVirus can't find their respective update servers. However, Bittorrent and Outlook still work fine and I can still ping IPs and Web addresses from the command window. The other odd thing is that one user account (on the same computer and that does not have Admin privileges) is still working perfectly.

I have a HP Media Center Desktop PC with Windows XP SP2. I had no problem using my Screen Saver or Standby Mode when I had dial-up internet service. I decided to go with Starband Satellite Internet Service and I have had problems ever since. My PC goes into Standby Mode with no problem but will not stay, after a time my monitor and PC come back on, at times my Screen Saver fails to come on. I have checked my power settings and reset them, they are the same as they were before. The modem is always on but if I unplug the power cord Standby Mode and Screen Saver work normally. Starband says the problem is not because of their syatem. I would appreciate help to correct this issue.

I had a trojan Virus in the computer. I think that I got rid of it, but I am not sure could anyone that can read a log please tell me if there is anything else left in the computer. The computer now doesn't stay on-line it disconnects itself. I called the company that provides me with my internet service, and they said that I need a filter for the phone line. The person told me that, that will take care of the problem of the internet disconnecting. I think that it could be the virus I had in the computer. I wasn't able to get on-line for at least a week, I had gone and checked the disk for errors and finally the anti-virus program was able to find the virus's.

This is not a hardware problem as it just seems to have happened to both my home and work pc's. The exact same issue, the F5 key no longer "refreshes". The only thing I can think of that has been installed recently on both PC's is XP SP3.

I changed the computer which is running Windows 2000 server from a domain to a work group and then rebooted. When it came back up The password to get into windows was no longer recognized.Can I reinstall windows 2000 without losing files and still get back into windows?I have already done the F8 thing, It seems to be booting fine. It's just when you get to the login screen it won't accept the password.

I am running a computer with Windows XP SP2. When I put a card in my card reader it used to automatically open the picture download wizard. When I put in a DVD it automatically opened Power DVD. When I plugged in my MP3 player it automatically opened its associated software. Now, nothing seems to auto start.

Ive tried doing the audio tuning wizard, but it still says I dont have a mic plugged in and it doesn't detect it.

I'm not sure exactly what brought this on since this is a nearly fresh install of windows, but I have had a problem accessing any web content with internet explorer except for the web itself (thanks to firefox). This means, Help files, Windows update, web forms, and many other features are completely unusable. Whenever I acess any kind of content through IE or it's engine embedded in windows, instead of displaying the HTML I am prompted to download it (open/save dialogged) this is a serious problem and I dont want to re-install windows yet again but it looks like I might have to if things keep going this way.. any help? I havnt been able to find a single mention of this problem on google

So I can't update windows or anything. I can't gt automatic updates to start. When i go in services.msc in start>run i try to start the process for automatic updates and it won't let me. I go to manual, click start, and it says 'could not start automatic update service on local computer. Error 1058: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it'. Now when I go to auto updates in control panel, it is set on automatic, however it doesn't do it.

About 5 hours ago my pc crashed, since rebooting my usb keyboard no longer works when it reaches windows login. I'm completely lost with this and it's infuriating me.
- I'm running windows xp
- Never had this issue before with keyboard, it's always worked until 5 hours ago
- There is no fault with the keyboard, I've tried in on 2 other systems and it works fine
- There's no problems with the USB ports all other usb devices work and work on all the ports.
- The mouse as well as all other usb devices work fine
- I've uninstalled the keyboard several times and reinstalled with no luck
The keyboard is a generic dell one using a dell system.
- The device manager doesn't report any issues. The keyboard is listed as installed and working properly.
- The keyboard does work in BIOS just not in windows
The only way i can get into windows is to use remote desktop from another pc so i can use another systems keyboard to control this pc which is what im doing now.Having endlessly searched for a solution, nothing has worked. There was a registry fix but it hasn't worked. One thing I thought may have caused it was before I had made a registry change to IRPStackSize to try to resolve a network issue. I reverted this change back and still no response from keyboard.

My daughters Disk Cleanup Utility was hanging when compressing old files. Microsoft has posted an easy fix but the end result is that Disk Cleanup no longer works at all. Has anyone experienced this problem?

I don't use System Restore all that often, but when I tried to use it after the last Windows Update, it didn't work. I didn't think all that much of it at the time, until I found out that someone else I know has a similar problem. I tried it again and it still didn't work. I have tried disabling it and then re-booting, turning it on again, re-booting and then setting another resore point, hoping this will clear any corrupted files as well as all the other restore points. Again, this hasn't worked. It is refusing to go back to any restore point I set. What is wrong? I have found this facility really helpful the few times I have needed to use it - in fact a life-saver and wouldn't want to be without it. I am using Windows XP Home - SP3.

I'm trying to figure out what's wrong with my parents' PC. They have WinXP, 512MB RAM, and a 1.2 GHz cpu. They've had a problem wth spyware in the past and have had it cleaned up, but it still boots up extremely slow. Usually it's around ten minutes or so until you can finally do anything on it, and even then, applications seem to take a while to start up and run slow after they do. Is there something I can do to see what's the matter with it?

I have been fixing a computer with more spyware than you could imagine on it. Its all clean now , all trojans and spyware removed, however in the process of removing these nasties, the computer has now lost its ability to connect to the internet. Networks fine, all obvious things have been checked, firewall, proxies you name it. Is there a way to re-install the internet connectivity services and files?

My main computer's (XP, SP3) Internet connection is shared among 3 other machines via ICS. However, one machine (XP, SP3) - which runs a couple of P2P programs - usually loses its connectivity (even file sharing) after a few days. I'm running Kaspersky Internet Security on the main computer. I've tried disabling it (for testing purposes) to no avail. I've also disabled Windows Firewall on both machines with no improvement. Using a router is pointless because it freezes after a few days (due to the P2P programs). I've tried 4 or 5 different routers (even the "good" brands).
Is it simply an overload in terms of the number of connections possible? Does ICS, in principle, face the same problems as a typical router? Because I've even tried reducing the number of P2P programs to just one and also limiting the number of connections it makes. (Not to mention "fixing" the 'tcpip.sys' limit on both machines.) Any ideas what the problem could be and how to fix it?

I have formatted 2 separate computers this past week and both of them gave me trouble with the Adsl internet connection. Both computers have been formatted with the windows xp cd (1 home & 1 pro version respectively) & formatted in dos -> ntfs file system
computer 1
win xp home sp1
this computer worked well until i installed sp2 on it showing me 'limited connectivity)
computer 2
win xp pro sp2 incl on cd
this shows 'limited connectivity'
the strange thing about this is that i could connect both computers to my network without the warning & everything works fine but when configured as standalones and connect the internet adsl modem into the nic they give me this error. tried winsockfx & microsoft repair tool from their site but to no avail. the prob could be from sp2 as the computers dont give me errors without it but i installed my own personal computer with sp2 & never had any problems with my nic or adsl modem. Could it also be that i primarily connected them to my network b4 i tried configuring them?

My dads new laptop is running fine except for the fact that we cannot get it to connect to the internet at all.I've searched these forums, as well as on google and tried a few fixes such as the official microsoft fix with the regestry entry but nothing is working at all. I'm planning on setting up a wireless network pretty soon and would like to get his computer online.I know the modem is working fine because my computer connects perfectly and I know the cable is fine beccause at the moment I'm using the same cable, just switching them back and forth.

I lose internet connectivity after a variable period of time of being logged into my computer. I can actually ping and do tracerts to verify that I can "see" the internet. But, my any other methods of accessing the internet do not work! I can't surf using a web-browser, my IM clients do not work, and I can't play any of the online games. I can still share files with computers on my local network.

My users are unable to access the internet via Internet Explorer 7.With Firefox and changes in the proxy it works good, however, unable to access with Internet Explorer.
I'm thinking maybe the user's profile has problem.However, after deleting the user's profile and have her logged in to create a new profile, it still would not work.
How come it works with Firefox but not with Internet Explorer?

Microsoft Windows, SpyBot, and Norton all sent a deluge of windows saying they had detected changes. SpyBot sent 7-10 warnings, one of them saying "SpyBot. Search & Destroy has detected an important registry item entry that has been changed. Catagory: System Startup global entry; Change: Value deleted; Entry: elkfqxcj; Old data: c:windowselkfqxcj.exe; [allow change][Deny change].Each of these SpyBot notices had a different entry. Since then my computer is extremely slow, freezes up when left for any time. A window pops us when opening and when changing applications titled "16 bit Windows Subsystem", saying:
C:WindowsSystem32AutoExec.NT. The system file is not suitable for running MS-DOS and Microsoft Window's applications. Choose 'close' to terminate application. [close] [ignore]

I'm wondering if it's safe to do that. I would guess that individual documents wouldn't be infected. I wouldn't want to infect my new computer. Afterwards, I plan to reformat the drive and re-install the operating system. The infected machine is an older one, so I may use it for simple word processing or older games or give it away. I know that reformating won't destroy old files beyond recovery but I'd hope it would take care of any viruses. I don't have any personal economic info on it since I haven't used a program like Quicken or Money.
I know the machine has at least one virus (about.com) and may have others since many of the programs that should take care of this stopped working after I installed Windows Service Pack 2. I gather others had similar problems after doing the same. Perhaps the most annoying is that I can't access the icons on the bottom of the screen. That includes files you minimize.

My son was just using his computer last week, it was working fine. He goes to use it the following day and he cannot connect to the internet. We have multiple laptops in our home along with a desktop. We all can connect just fine. We can't figure out what is going on with his. I've tried to reboot,we've tried connecting to the hard line, we've checked out the wireless router and the signal is fine. We've played with everything that we can play with and nothing works?

Pc crashes the internet all the time, he is working on a ACER Laptop,everyone else gets internet just fine, it is his laptop that won't get it all the time, and when he does get it, it sometimes only lasts for up most to about 3 to 4 hours. if he is that lucky.could this be an internal problem? or could a file have been corrupted somewhere in the system?right now he is running a disk scan to see if it picks up anything but i don't think it will.

Audio died recently, though I realize that now in retrospect.Started running real slow, finally died 4 weeks ago, MOBO wouldn't recognize Hard drive.after trying everything under the sun, I finally bought new harddrive. I installed winXP sp2 After installation, No Network connections.After trouble shooting I discovered that when I change the BIOS to enable on board ethernet, the MOBO recognizes that the PCI ethernet card is there and installs network connections...BUT, when I plug in the cable from the router, It does NOT see the bandwidth. It reads 10MBps when my laptop (plugged into the sme router ) reads 100. Additionally there is a green light on the back indicating that there is a connection AND my router lights up like something is connected.My device manager WILL show the ethernet card and that it is working properly. BUT no network connection (can't browse the I-net, can't connect to other computers on my network, PC is not visible to others on the network. total bytes sent and received remains 0.
