Hi Chrome
You are saying that AVG bogs down systems , can you say what its behavior pattern will be so I know what to look for .

I use AVG & have not experienced any problems.
I like it because it can do automatic scans at 3.00am for me, every day.

Maybe I should swap to Avast
Can that be set to auto scan each day or does it have to be activated manually each day.
