Good afternoon

My notebook is Acer 8930G and my network adapter is an Atheros AR8121/AR8113/AR8114 and i used to have as a wired router a Dlink 524T, which i changed with a Netgear DG834 during my many attempts to resolve in vain my internet problems as i did with my ethernet cables.

About a week ago,suddenly my notebook ceased to have any internet connection and my status varied from local only to limited connectivity while both the green and orange lights on the adapter came and went continiously.
After a casual scan with Malwarebytez antispyware,it turned out that i had 9 infections from the trojan BHO.After innumerable efforts and formats,i somehow cleaned(so it seems without being 100% certain) my PC.The only thing is that the problem persists with the connection,while two other computers that share the network with me didn't have any problems whatsoever.

Is it possible that my ethernet card was damaged by the trojan?If anyone could help me out or at least enlighten me,i would be much obliged!!!!

Thanks in advance

If you ever get a local only connection try opening up a Command Prompt and typing in ipconfig /renew to renew your IP settings. I see that you're running Windows Vista and I've found out with experience as a Commercial Computer Technician that Windows Vista can be pretty troublesome when it comes to networking.

Have you tried to unplug your router, and wait a minute before plugging it back in? If so, try doing a hard reset on your router. If you have to set your ISP's information statically, then take a note of those settings first to save yourself a phone call.

If you have any firewalls installed on your computer, possibly included with your antivirus software, try disabling those and try to reconnect to the internet.
