hello,

my laptop is dell ispiron n5010 and I have win 7 64bit home edition , I had a virus called win32.sality or something like that , that made all my program stop working , O downloaded an antivirus , and some message asked me to activate some kind of firewall and I presses ok , the wireless network changed to limited connectivity , I tried to reinstall the wireless driver , nothing happened , later , the available wireless networks disappeared , so I connected the network cable to connect to the internet using ethernet , it didn't work as well , and after many trials with the wireless drive , it's name doesn't appear now in the device manager , it says network adapter and has a yellow ! next to it , there is also something called realtek pcie fe family controller and it also have a yellow ! next to it , so I tried a usb broadband stick to connect to the internet that should have nothing to do with any drives , it said that the connection can't be established .

the network troubleshooting sais that there could be a problem with the realtek pcie fe family controller drive , and it used to say before that there is a problem with the (intel ...) which is the wireless adapter (but i don't remember its full name)

and I have no backup or restore point

can someone help me with that
