How to re install a program from my laptop?

Last night I was cleaning up my laptop of random virus program files.

My laptop is windows 8 and somehow I deleted a program that lets me connect to the Internet using my hot spot on iPhone and many other network selections.

I have tried setting up a new connection or network but my laptop can't find my iPhone or any other networks.

Do I have to re download this program file or is there something else I can do? I have no idea what the program file was called.

Any ideas?!

If all you did was follow your antivirus options to clear virus threats, then it is likely that the application you are now missing was infected with a virus.

I would suggest you use an alternative application, ensure you virus check the application before installing it, and also make this precaution your standard procedure.

You don't need any software to connect your computer to a personal iPhone hotspot. To connect to a hotspot all you need to do is turn on your 3g or LTE connection and create personal hotspot. You need to enter the password once only.
