I don't think so. I frequent quite a few forums but mostly lurk on similar sites. I really don't see what my results not meeting your expectations has anything to do with possibly knowing me, lol...
Heuristics aren't "off" by default and I don't know why you'd assume I would disable them. However, let's see what happens. As I had already uninstalled it, I plopped the installer onto a usb stick to let it run on another rig with recursion depth left at default 20 and everything else maxed - including heuristics, which was set to 'high'.
Result: 0 hidden objects, 0 detections, 0 suspicious files, 2 warnings
You were right on the 2 'warnings', but unfortunately merely due to coincidence as both are unrelated to Win7:

One is obviously the avira installer whereas NPVR/uninstall.exe is from WinTV. It begs the question why Avira is even flagging its own installer. Then again, it does have a reputation for false-positives as well.
I spend far too much time on the net, more than I should. I download quite a lot and don't exercise any extra caution save for some plain old common sense - and take care when websites are flagged by Norton. What I don't download is pirated content and I have no interest in cracks, patches, or keygens. If someone ventures into that area and gets infected it's their own fault, regardless of what protection they're running... good for them, really.
At the expense of freedom? A resource hog? What are you running, a C64?
Norton is currently sitting in the tray, memory usage is at 6MB and CPU usage isn't registering. Considering 6MB a resource hog is downright comical. Further, if you're running the free version of Avira, Avast, etc, they won't be sufficient to safeguard your PC on their own. Most people using free protection typically run 3 individual apps.
Anyway, seeing as how I currently have both Norton and Avira installed again, let's see what happens when I ask both to actually do some work:
The Norton "resource hog":

(csrss.exe isn't part of Norton, btw... I should've cropped it out)
Avira:

Seriously?
Both are set to normal priority and are running on similar i7 machines. I even ended up installing Avast, which shows similar usage to Norton while actively scanning.
You know, I'd actually consider apologizing if it weren't for you labeling people idiots and what not
