Wow, thank you very much! All devices are virus-free now 
It seems like the phone was not infected after all, just had some .lnk files and hidden folders (which MCShield corrected), but the virus was not there because I did run the avast antivirus and found nothing. For the USB I reformatted and it’s fine now. But I still have a question: in the phone appeared a file called “config.dat”, should I delete it?
