Virtual Box not opening with Windows update KB4579311

Post by saketb »

I am using Oracle Virtual Box Version 6.1.4.
A few days ago, Microsoft has released a new cumulative update KB4579311 for Windows 10.
After this update, the oracle virtual box fails to start, giving below error.
"This app can't run because it causes security or performance issues on Windows. A new version may be available........."

How to solve this problem?
