I rarely run scans other than during beta testing (or in relation to forum topics) and I certainly haven’t run a custom scan, so its Smart, Quick and Full virus scans only. I have found some scans a little slower to little difference.

But that isn’t what I’m on about, it is about scans that are so quick, e.g. straight to the big Green tick and Great No issues found with nothing in between. No logs etc. etc. But what is more of a pain is the inconsistency, sometimes it works just file with no ‘big Green tick and Great No issues found’ until the scan progress has actually completed.

If you are only talking system CPU/RAM performance (I wasn’t), I haven’t really noticed it one way or another. I don’t sit at my system with a stopwatch to directly compare (which most users aren’t), not that I have retained any such data from the prior installation. After all most of us just notice when things are much slower.
