*Solved (Kinda)* Windows 7 x64 does not find any wireless networks after virus

[Oifish]

My roommate's brand new pc (which I just built for him) recently had a virus. The virus was queryexplorer.exe and "click potato". I've removed them and ran multiple scans using malwarebytes, avast, and hijack this showing that the pc is clean. Only problem is that now windows doesn't find ANY wireless networks. I've fully uninstalled and installed the wireless card multiple times, but no change. I have no idea what to do next.... His system specs are as follows:

Western Digital Caviar Blue WD3200AAKS 320GB 7200 RPM SATA
G.SKILL Ripjaws Series 4GB DDR3 SDRAM DDR3 1600
ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner
Thermaltake Silent 1156 CLP0552 92mm CPU Cooler
EDIMAX EW-7128G PCI Wireless Card
GIGABYTE GV-N460OC-1GI GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5
GIGABYTE GA-P55A-UD3
CORSAIR CMPSU-550VX
OCZ Vertex Series OCZSSD2-1VTX30GXXX 2.5" 30GB SATA II

How about doing a system restore if you can...or...[ cough ] restore your latest backup. You did do a backup after completing your build for him/her..right ?

By "Uninstall," do you mean you just unplugged your card and plugged it back in? Used a CD? Or manually installed the driver?

It sounds like you have a driver issue.

I uninstalled the driver using the installer program from edimax's website, restarted, then reinstalled it.

Is there a separate way of installing the card manually? Like just the .ini file or anything like that? Sometimes I find that manually installing a driver helps, but it still sounds like a driver issue to me. Only other thing I can think of is that your wireless zero configuration service may be turned off (at least this is what it's called in winXP, I'm not sure what the equivalent is in win7 in terms of a service name).

The virus may have corrupted your Winsock settings.
Try running this program, it also works with Win 7: http://winsockfix.en.softonic.com/

Or try Microsoft's Fix It tool: http://support.microsoft.com/kb/811259

I tired both ways of fixing winsock, but it didn't help. Still doesn't find any networks.

Try this.
The Edimax card uses a Ralink RT61 chip. Download the Ralink drivers: PCI/mPCI/CB (RT256X/RT266X)

Uninstall the Edimax drivers, in Device Manager uninstall the Edimax card, reboot and install the Ralink drivers.

I would also recommend popping in the Windows 7 install disk and doing a repair install. If any windows files were infected, they may have been deleted.

Tried these driver and it still didn't change anything.

The only repair option on the Win7 disk was for a boot repair which really doesn't help anything since windows boots fine. And the only system restore was for a date after the virus.

Solved (Kinda). I just deleted the partition and completely reinstalled windows. Everything is working fine...
