While I agree with you in theory, this will only help a small fraction of us techie users. The average user is going to see a new, weird icon on their eBay Auction tab and call their computer company to ask them what it is and if they're being hacked.

When I did support for Apple Care, every single update if it had new or extra icons we always got lots of calls like this.

I'm sure some good UX could alleviate this. Maybe a spinning gear icon? Maybe a battery draining animation? Something to signify, 'this tab is doing some heavy lifting right now'.

It's actually a pretty rational response for someone who is only moderately aware of what is going on in their computer. If they are aware that malware and adware can cause unwanted changes on their computer, perhaps because they've been bitten before, then a new icon -- even one that is easily interpreted (which this one would not be) -- looks scary.
