I have internet access at home and about a week ago, when I tryed opening webpages in Mozilla or Internet explorer I was not able to access any sites, I have tried on different occasions. I suspected malicious spyware and installed and ran Ad-Aware SE, ***it could not receive the definition updates***. Although I did still run a scan. My internet connection has always worked, so I think something harmful is at work. Now I think it's a virus that has hijacked my internet connection or done something similar, because the connection status of my wireless access says that signal is strong and is connected. I am just not able to visit any websites. Should I check the hosts file or install AVG Anti-virus and run a full system scan? Should I make the HOSTS file read-only? Does the AVG 6 free edition have the latest virus definitions, or will I have to wait until they release the 7th free version? |

There is no answer at this time. |

So your connected but can't access the internet in two different web browsers. Could by a firewall problem blocking web browser access. I suspect your internet connnection is dead . try running ping your.isp.name.net.com or what ever from a console window. If your firewall is not blocking ping then you should get some results if your connection works. Try rebooting your router or access point. |

Hey - did you find out what's blocking your internet access? I've got a computer with a similar sounding problem. It is on a home network with other computers, sharing a DSL connection through an 8-port router. The other computers can get on the internet just fine. This one computer can ping the other computers AND ping internet servers (such as www.yahoo.com), but can't access web pages (through either IE or FireFox). I tried Spybot Search & Destroy, but it can't access it's update site. I know of another computer with similar symptoms! |

Just picked up a similar problem on my laptop, I have both a wireless broadband and a dial ip, which are connected, but neither Explorere or Outlook can acess the internet on either connection. Explorer always goes to the same address no matter what I type in. I had Nortons enabled and up to date. Has anyone else encountered this? |

Is this a new virus? I also have the same problem with 4 PCs connceted to my home LAN. The 4 computers are able to brwose the computers and access shared files in the LAN but whenever I try to browse the internet, these 4 computers are blocked. I have firefox 1.0 and internet explorer installed. I was so pissed off that went to format the hard drive of one computer and installed win98SE. But even after installation, LAN is accsible but no internet access! If you guys find a solution to this please advice by leaving a comment or a link here. thanks! |

I too am having trouble accessing all the major search engines. It's a miracle I made it here on a google server. Google and Yahoo better get the word out on how to fix this. If it keeps spreading, no one will be able to access their sites. Perhaps have Lou Dobbs on CNN tell us how to fix it. I may never be able to get to here again. I have used mcafee, msoft and spybot s&d to search for this malware. msofts antispyware finds and removes several culprits, but the problem keeps coming back. Help! |

OK Kids here is the deal. You got hacked by a spyware/malware bug and when that happened the bug modified your DNS server entries and inserted 2 ip addresses that are bogus: I found these although you may find others. 209.47.15.118, 64.157.143.38 . You will need to check with your ISP if you don't know your correct DNS Servers. If you find these in your config, just delete them and all is fixed. No need to reformat your disk. -CK |

Sometimes after uninstalling software, Winsock gets corrupt, or some of the operating system components at network level stops working. It happens due to some improper uninstallers. In this case, we always suggest to format machine and reinstalling the OS because there is no way to detect which part of software peice got corrupt. Its not any virus which stops you but its mailicious uninstaller which uninstalls something which we do not know how to bring it back. If you just reinstall the windows operating system or just reinstall Internet Explorer Service pack then there is possibility that it might solve the problem. - Akash Kava Our free IMAP/POP3 service at http://www.evenmail.com |

There are a number of possible scenarios. I've been dealing with this problem on machines on a daily basis for the past 6 months. If such software as AOL Instant Messenger, Outlook/Outlook Express, etc connects then it is a browser problem. There are a million Browser Hijacks that could cause this. I use HijackThis to remove them personally - but I also know what to remove. If none of your software will connect, but Windows says you are connected here are likely causes: Under your TCP/IP settings, your DNS servers may be set (static) to malicious servers. Your hosts file may be corrupted. Or the most likely cause.. Winsock is corrupted. In Windows ME and earlier Winsock was seperate from the operating system. It was easily uninstalled and reinstalled. In Windows XP (and 2000 I believe) Winsock and the TCP/IP stack are built into the operating system. They cannot be uninstalled. BUT there are a number of ways to fix a corrupt Winsock without reinstalling Windows. (reinstalling Windows should be a LAST CASE scenario) I suggest you first open a command prompt and type "netsh int ip reset resetlog.txt". This will reset Winsock. If that doesn't work, download LSPfix from http://www.cexx.org/lspfix.htm. This repair software fits on a floppy and can fix most all Winsock2 problems. |

CHNET (google answer user) was right, I had a computer tech fix the problem. It was a trojan horse that had modfied the IP addresses and DNS entries so that my connection was being hijacked. Possible Solutions: 1) install AVG Anti-virus (free edition) and run a full scan, if it is a trojan horse, it should find it. 2) install and run the free version of ZoneAlarm. ZoneAlarm is a firewall program that helps prevent unauthorized access to your computer by others. 3) have a computer technician call your internet service provider and get the correct IP addresses and DNS entries to replace the bad ones. Good Luck! |

Some good fixed for this are Windows XP With SP2 in the run command type in netsh int ip reset 1.txt hit ok then netsh winsock reset hit ok or on other OS this is a great fix http://www.supportcave.com/winsock2.html here's what the file does Windows 2000/XP __________________________________________________________________________ With Windows 2000 and XP, this was not possible, due to the fact that TCP could not be removed or uninstalled, and even if the Winsock keys in the registry were deleted, they will recreate themselves, but with no relevant data, therefore making them useless. Some research in this matter, it was found, that these Winsock Registry keys were not unique to any particular machine.... meaning they could be transplanted from a working computer, to a broken one. Other factors can play a part in successfully restoring these winsock values, such as disabling the network adapter before the import of the new Registry keys. Also with Windows XP came the very handy "netsh.exe" with the commandline to Reset TCP. Although this will reset TCP settings, also removing any tweaks and other modifications done, it does not touch the registry Winsock keys. The most common symptom would be a Valid IP address, but no ability to view any Web pages, as well as the "0.0.0.0" IP address symptom and Various Socket Errors. Manually Fix: 1.) From the commandline enter the following: Netsh ip int reset resetlog.txt 2.) These 2 Registry keys will need to be replaced with known good ones. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock2 The "Hosts" file. This file (having no extension) and residing in "C:\Windows\Hosts" for Windows 95 - Me versions and "WINDOWS\system32\drivers\etc\Hosts" for Windows XP. Often this file (blank by default) can become littered with entries, and again, after the removal of Third Party Advertising Clients, that were installed as bundled software with many P2P file Sharing programs, this "Hosts" file retains entries that may be no longer valid. Generally resulting in some web pages and Domains coming up "Blank". ____________________________________________________________________________ The Winsockfix Utility will: 1.) Detect your current Operating System 2.) Release the IP address, taking you "Offline" 3.) Reset the TCP stack using Netsh.exe (Windows XP only) 4.) Delete the current Registry TCP and Winsock Values 5.) Import new "Working" Registry Values 6.) Backup any Current "Hosts" file 7.) Replace the "Hosts" file with a default one 8.) Reboot the Computer ____________________________________________________________________________ No one should rely on "Quick Fixes" to resolve their connection issues, only by taking responsibilty for the software you allow to be installed, can you protect yourself from re-occurring problems. A Google search for information relating to "SpyWare" can usually point you in the right direction to get information on the Program you wish to install or Try. Chances are there will be many reviews of it, and you get a feel for the type of program it is,and what some of the issues with it will be from other peoples opinions. An understanding of why some programs are "Free" in cost,but you end up paying with damage to your system settings, Background running Programs, whose only purpose is to plaque the User with non-stop Pop-up advertising, and an overall drain on system resources. ____________________________________________________________________________ |

I am having the same problem as JackC. Have anyone found a solution? I am able to ping to yahoo.com or to google.com before activating internet explorer. But once I activate IE, I lost all connections. Not able to ping anymore. This happened only on 1 PC. My notebook, which gets access through the wireless router is not affected. Must be some kind of virus or spyware. I ran spybot search and destroy, but did not help. Yes, and of course spybot could not get access to its update site. Anyone, got a solution? I search out my ip and dns. It is set to autodetect, and I did not see any bogus IP address. |

Found out what was wrong with my internet access. But do not understand why? Appreciate if some techie fella can enlighten me. Apparently The problem lies with the graphics card driver. I uninstalled the graphics card driver and downloaded and installed a newer driver version. Once loaded it worked as a breeze. Now I can have good access to the internet. My graphics card is from Nvidia, Geforce 2, 128M memory. Question is, can graphics card block access to internet? I would expect that if a driver is not functioning properly, then there would be problem with the monitor's display. Instead everything fucntions well, except the internet. Anyone, have an answer to this phenomenon? |

Just a week ago around 7th of March, my xp got affected with almost same problem as described by banjobarry-ga. The symptoms are: - No web pages get displayed for any of the websites - If we reboot the pc/xp then internet web page access works fine for the first few minutes. After that it will not work. Tried both IEand Mozilla. But every thing in the setting seems to be fine. Checked the Tools Options, etc/host etc. All the connection settings are proper with DHCP enabled, Automatic IP address, DNS address etc. though: - ping works fine - nslookup also works fine. it shows the correct ip address to hostname mapping I tried MS Antispyware beta1 and AVG Free both found some viruses and of course rebooted the machine. But no use. I still ended up with the same problem. Finally I started removing winsocks entries in the registry. After that I could even use ipconfig and nslookup. I tried system restore from the control panel. Wow. It worked. I restored the system to the day where I had no problem to access internet. After restore, the pc boots on its own and then finally, the problem is gone. Since I restored the system to a backdate, all the visuses are also got restored. Again used Antispyware beta1 to scan the pc to remove all the affected Drives. Also, used AVG Free to remove remaining viruses. The solution: Use system restore. |

I was having a similar problem. I downloaded some junk off the Internet and suddenly my IE would not connect to google or various other sites, but my AOL software would connect. I tried cleaning it up in every way possible--system restore, antivirus ware, spybot, pinging, you name it. I was due for a new computer anyway, so i bought one, set it up and it had the SAME problem. I hand't transferred any of my old files, so it couldn't have been malware or viruses. I read that my IP might have been hijacked, but when i did a walk through with my ISP tech, they said everything was fine, and my IP was different everytime i logged on. I downloaded Hijack This, but don't know how to use it, and i downloaded AVG anti as well, but no viruses found. Finally, after my third call to my ISP, they told me that the bug may be residing in my wireless router, which goes to my non-networked laptop, which was also experiencing the same problems. I took off my router, and did the Winsock reset listed below, and voila--everything is cool. I just have to call Linksys now and find out how to get the bug out of my router, so my laptop will be internet ready again. Hope this helps someone. |

I encountered the same problem recently(can access internet by IM s/w but not trhu browser) and when i used Spybot S&D , it found a DSO Exploit. I fixed it by editing registry. http://forums.net-integration.net/index.php?s=ced7824ad304d2180fc68355cd0c6cdc&showtopic=17159&st=135 But now i have a similar problem. when Spybot searches, there is not detectable problems and no viruses found.

thanks a million for the advise about resetting winsock. The 2 step proceedure worked in a quick minute. I was ready to wipe the HDD and start over. I had even tried static IPs and putting in correct DNS servers, still no internet but I could ping the gateway and the DNS server. I am the only techie in our organization, don't know what I would do without your help! Thanks! |

This one might be strange. A couple of months ago my FireFox became unable to go on line after an update from MS website. After this, all of my protections of anti-virus programs and ZA firewall were unable to update. Norton AV 2005, SpySweeper, and FixIt did not detect any problem even in safe mode, and currently all are not updated. ZA's trueVictore is not working. I uninstalled and reinstalled all of them, but nothing worked. I restarted the pc with the emergency CD that came with the computer and revived it to its original factory state. The problem continued with no change. Moreover, I cannot download anything neither an update from MS, or download from CNet. I was able to download some tools from major geek and some European sites. Running these tools, I found TR/Rebootpc.B in about six files. After deleting them, the problem I described is still there. I have communicated with all companies, but no one has the answer. Is there someone to help with an idea? |

I had something pretty similar, was hoping for a suggestion. At home, whenever I launch IE, I'm okay - but if I go to a link that is a popup (say through a link in an email, or just a link on a website that has their links pop open another window), the popups all go directly to the mail.yahoo.com login page. I rebooted and this still happened. Then I brought the laptop into work, and everything works fine. The popups are going where they want to. But I assume when I get home I'm going to have the same issues as before. Would this fix: "Some good fixed for this are Windows XP With SP2 in the run command type in netsh int ip reset 1.txt hit ok then netsh winsock reset hit ok" Possibly be appropriate if I still have issues? Any other ideas? Thanks for any help. |

Scruff 12, I would check your hosts file, which can be found on your hard drive here: Windows 2000/Windows XP - C:\system32\drivers\etc\ You can right click the file and open it with Notepad to look at it. After it's open, if you see any entries for mail.yahoo.com , then you now know what the problem is. If there are any such entries, delete those lines of text, or call up a computer tech guy, and have him check out your computer if this does not solve the problem. |

location of hosts file C:/Windows/System 32/drivers/etc this is where the hosts file will be, and sometimes spyware, and even trojan horses can screw up this file so that your computer will always go to a certain website, instead of the one you've typed in. |

I have just had the exact same problem. Internet connnection fine for a while then it dies. I can ping, but any other connection is dead. I have a router for 2 PC's. After much searching and checking I found the solution... it was a spyware exe called sysram.exe. I found it sitting in my c:\windows\litmus folder. Had been there for about 2 months doing nothing till now. It must of been doing something when I disabled my network connection because the exe crashed and Windows kindly let me know and asked if I would like to send a report. I deleted the folder and searched and destroyed the registry for sysram.exe. And now fully working again. |
