This is probably a firmware problem...

Have you installed the USB Flash driver? Link: USB Flash Driver Installation - Guide Without it your phone is invisible to flashing tools.

In this case I haven't said anything. But I couldn't know if you installed the driver or not.
The PC viruses cannot do anything with phone(totally different OSes), so don't worry about them.
When you connect the phone, hold down the 2+5 buttons instead of C, and try to connect it. Now what says the XS++?

Did you try removing the battery and putting it in again and then connecting it to your computer.
