Here's my problem:

I have a laptop and a computer. Both are connected to the internet via wireless adapters. Whenever I turn on my desktop the Internet goes out, but when I only have my laptop on the internet's fine. When the internet does go out because of turning on the desktop I have to turn off the desktop, turn off the routers, wait 5 minutes, and then turn the routers back on. I have Panda Antivirus on the desktop and Norton Antivirus on the laptop. whenever I run the scan on Panda on the desktop it keeps saying theres a trojan/spammer and it always says it has been neutralized, but everytime I scan it it's still there. I found the file that has it but I'm scared to manually delete it because its in the Windows system 32 folder. Its called perfc000.BAT.

-Laptop is Dell Inspiron 8100
-Desktop is an HP
-Wireless ROUTER is Netgear So the Desktop is also connecting wirelessly ? ?
If so travel to Control Panel/System/Hardware/Device Manager...
Right click the wireless adapter and select advanced...under power uncheck "allow Windows to shut this device down to save power"

Re-boot.
Then on the Desktop machine go to Start/Run and type cmd and hit Enter...in the Command window type in ipconfig /all and hit Enter.
Save it to .txt and post it here...It's very unlikely, that you have any legit ".bat" file in system32 folder.

Just to make sure...
