I have AVG 7.0 paid and it has been set to scan all my partitions.
If AVG FREE 7.0 does not have that facility use the scheduler, to set up scans for the various partitions you have.
You should set each scan to start at least 1 hour after the previous one.
Is it possible with this latest free version to scan ALL partitions during a scheduled scan? I'm sure one of the older versions used to scan everything, but this latest one just seems to scan within the C:\ drive.
I've tried all the settings with no luck. I have to manually scan the entire system.
