Let's deal with the printer first. The file you deleted should have no bearing on that.
We'll try the short version first. Go to the Control Panel and open Printers and Faxes, right click on your printer and choose Delete. If there is more than one printer, Delete them all. Make sure your printer is powered on and reboot. Windows should detect and install your printer on restart...if it doesn't we'll reinstall it manually.
How do you connect to the internet?
What I mean is when I go into my printers folder, what was two printers listed have vanished so the folder is empty. And I can't print and for some reason when I plug the printers into my laptop it doesnt automatically detect it like it used to. So when I try reinstalling the software manually nothing happens.
I connect to the internet via my broadband modem, but since the software in Network Connections have been deleted I can't connect anymore. So now I'm using my wireless card and it has automatically connected to someone else's wireless router. (I know I should start using my own internet connection)
Ohhh I don't know how this has happened, I just wanted to get rid of a virus. V_V
Do u think I should just reformat it? Looks like they're gone forever.
