The aswnet.sys file is part of the Avast Antivirus software package. You can try uninstalling Avast and reboot. Restart the computer again and then download and install a fresh copy of Avast (if that is what you are using). After that, reboot again and hopefully everything will be good.
now to actually uninstall it, I would download the
Windows 10 media creation tool and use it to make a win 10 installer on USB
change boot order in BIOS so USB is first, hdd second
boot from installer, on 2nd screen after languages, choose repair this pc, not install
choose troubleshoot
choose advanced
choose start up options
hit the restart button
choose a safe mode (it doesn't matter which) by using number associated with it.
PC will restart and load safe mode
ONce in safe mode, right click start button
choose control panel
choose Programs - uninstall a program
remove Avast
reboot PC and do rest of steps suggested above.
