With the Stats RealTime data open:
1. the CPU peaked at 56% and settled to about 50% for as long as I kept it open.
2. There appears to be a memory leak as it just keeps on increasing, currently 1.3GB and still going; 1.5GB.
I have now closed the Stats window:
3. the CPU returns to 00% and memory is returned to a modest 34MB whilst the UI is still open.
4. Closing the avastUI screen and CPU remains at 00% and memory of around 9MB.
Edit: it's still in v2261.
