I running windows 10 64bit and oracle virtual box which runs windows 7 32 bit with avast and have used this for the last 2 years with no problem
Just updated to version 17.1.3394.0 and the virtual box and programmes inside have now slowed down to a sate that they are unusable!
any suggestions?
Reboot the virtual OS 2 or 3 times and see if it makes a difference.
Running W10 in the Oracle VM here without a problem.
