Hi Dear,

I am here to share my problem and hoping to get the perfect solution. Recently my HP Pavilion notebook was infected by a dangerous Trojan horse virus and causing many problems. But I was successful to remove the virus by using Kaspersky Anti Virus 11.0.1.400 version and every program was running fine except Internet connection. I am using a wired DSL connection which is running on Windows XP. I have checked the local area connection and it says connected. By checking the LAN properties I have found that data sending is ok but receiving is showing ‘0’. Somebody please help me.

Thanks in advance for the response.

Hello Charlie

Trojan Horse really causes a great harm to our computers. so you need to be careful about your antivirus. Firstly checkout your firewall settings. If any firewall rule is created then the LAN port may start behaving like this. You can check the IPV4 address from the LAN settings. Check if the network is same with your pc. Ping your default gate and see if the ping is successful or not.

You can do one thing restore your system to an earlier time so that the configuration goes to a previous time. You can do it from Start, all programs and then accessories. From system tools you choose the system restore. There you choose a restore point where your computer worked all right. Then click next and this is how your computer goes to a good position. Then check your connection.

I have here some advice that may help you fix the problem:

1. Try Unplugging wireless router then plug it back after a few minutes and check the connection.

2. Troubleshoot your connection by going to control panel > network and internet>network and sharing center> then change adapter setting. You will see the LAN and your wired DSL connection. Try to disable and then enable the local area connection.

3. Renew your IP address.

Though viruses cannot affect the hardware itself like the network card but it can damage the driver because it is still a program. If your internet connection is no longer working properly after getting infected, the virus probably damaged or corrupted the network card driver. To fix the problem, just uninstall and reinstall the network card driver.

First, since the computer recently got infected, you should scan it first with a virus removal tool. Download Sophos Virus Removal Tool and install it. Once installed, start Sophos then wait for the virus signature database to get updated. When updating is complete, click to start scanning your computer. You don’t need to uninstall or disable your antivirus to use Sophos Virus Removal Tool.

It works alongside any antivirus program you may have. The tool scans everything on your computer including external devices connected via USB port. When a virus is found at the end of the scan, remove or delete it then repeat the scan over and over until it no longer detects a virus.

When it is finished, close Sophos then download the free version of Revo Uninstaller and install it. Once installed, start Revo Uninstaller then select your network card’s software among the applications and click “Uninstall”. Follow the normal uninstall process. When you are prompted to restart the computer, click to restart later.

When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer. When it is finished, close Revo Uninstaller then restart the computer. After booting, install your network card’s driver back. See if this works.
