Networking Problem

Well,my laptop was working fine, until earlier yesterday, i got a virus, the virus was wmcodec I Was using Norton Internet Security too....
It didn't let me open up Mozilla or IE ( I am unaware if this is the problem which caused it, i was able to use msn and stuff whilst i had the virus [ when i opened Mozilla it came up with this window saying Mozilla FireFox has crashed, IE just shut down and said it didn't work])
I need to find out what the driver for the wireless is so that i can redownload it and install it/ update it. could you please upload a direct link to the dowload if you find it? I have searched for hours.
And if i put it on a Memory Stick and then put it onto my laptop, will that work?

Or if i got a ethernet cable, would i be able to connect to the internet off that and update my drivers?

All feedback is welcome, im a noob when it comes to stuff like this

close all your inertnet applications do a network reboot of your system . see id your network comes up without any warning then every thg shld be fine . use some other browser.... hope this works.:rofl_2:
