SosVirus

Hello,
I have USB Premium installed on two W10 systems (HP PC and HP Laptop)
I do the PCs backup with USB discs .
Last time I connected the PC backup USB unit in to the PC the USBFix shows it was infected.
The same thing happen with the Laptop backup USB unit at the Laptop.
But I switched the USB units: PC backup in to the Laptop and the Laptop backup in to the PC
and in both cases USBFix find the units clean.
What is happening?
Thankyou in advance for your help.
Regards,
