Kaspersky won't catch mobile device viruses in most cases.
It appears that when you connected your phone to your PC--you transmitted a virus to the PC from the phone, or vice-versa. In either case, on the PC side you should ditch the Kaspersky (uninstall it), which should re-enable
WD (Windows Defender) which is the built-in AV that comes free with W10. Use WD to scan/remove all viruses found on your PC. Make sure to disconnect your phone when doing this scan. Additionally, download the free
MALWAREBYTES antispyware from
malwarebytes.org and scan/remove all spyware viruses found on your PC.
Next, you'll need to immediately make a backup of all your personal data on that phone to external media such as external HDD, flash drive, or Cloud storage account. Then you should do a factory reset on the phone (to remove any viruses if the phone was the infection vector), and when the phone reboots the very first thing you should do is to purchase a low-cost phone AV such as Lookout or Avast for $9.99 per year. That's protection on your phone for less than $1 per month. Run the Lookout or Avast scanner on install, and it will automatically find any viruses lurking in your phone (most will be wiped out by the reset), and remove them. Avast makes their AV for Android, Mac, and Windows Phones; Lookout makes theirs for Android and iPhone (IOS).
Posting back specifics on your phone such as Make/Model as neem asked, will allow us to further advise you.
