Earlier quoted context omitted.

Twice daily "Adobe updates are available, please download and install!" - annoys me to no end

It frustrates me that EVERY day when I open the Pandora windows desktop app(lication), an Adobe AIR popup asks to install an update. EVERY day! I know Agile is hot and all, but is their AIR framework so fresh that they constantly have to fix things?

This is an exaggeration. I did not have to update Adobe AIR today.

I did update it yesterday though!

One bit of advice that should be up there is to run an ad blocker and a flash blocker (not so relevant anymore now that FF started blocking by default). I know, I know, websites depend on ads for revenue. But ads are also a great way to deliver exploits, in addition to all the personal tracking ad networks do. Our number one priority is to protect ourselves, not to protect website revenue.

ublock origin is the original creator maintaining the code. it is better than ublock!

Some others potentially worth installing:

But are the security experts actually safer online? The study seems to assume that they are. It may be a fair assumption, but it would be interesting to know if it actually is true or not. It would also help validate the security practices. If it turns out that the security experts got infected just as much, or only slightly less than the non-experts, then following their practices might not be worth the effort...

Are the security experts are target more likely to attract those who might want to compromise them for bragging rights?

Yes, plus it might be true that security experts visit riskier websites because of the nature of their research. It's a difficult task to try and balance these factors out to make a useful comparison.

The thing that software security people do that most normal people don't do is: browsing and accessing email in a virtual machine, not their actual machine.

Browsing makes sense, but why email? Unless you run an OS and email client that 1) renders HTML mail by default (making you vulnerable to browser engine attacks) or 2) makes it too easy to run executable email attachments, then is an email client really higher risk than many other pieces of software?

My personal work email flow involves clicking a lot of links. Email is quite tied to web browsing for me, so if I wanted to make sure that all of my browsing was done in a VM, and I wanted to make it convenient, I would do my emailing from the same VM

Any time you provide a vector for an attacker, you run the risk of being exploited. Email is even worse than web browsing, because an attacker has the ability to send it to you, rather than waiting for you to go to their site.

I would never claim to know my email-renderer so well that I was 100% confident that it didn't have any attack vectors, particularly with all the crazy things you can do with unicode nowadays - much more straightforward to just read it in a virtual-machine. That way, even if you guessed wrong on the attack surface of your email client, the damage is contained.

Or due to the fact, that antivirus companies make money on selling antivirus software to non-experts and have a long history of advertising it to non-experts as a security solution.

It depends on what your definition of safety is. The perspective of this paper probably relates to compromised accounts and information leaks, not adware infections.

I haven't completely read the full paper yet (it's pretty big), but in a brief scan, I can't actually find any definition they use for staying safe. They talk about 'protecting their security online' and 'to stay safe online', however I didn't spot anything more specific.

As you point out, there are a variety of attacks and big differences between e.g. leaking a password or getting a virus infection. But since their highlighted techniques cover both of these attacks (virus scanners, password best practices), you have to assume that they are relating to a whole range of attacks.

Non-developers probably do everything that would be valuable to an attacker in the browser and/or via email. (Heck, what else do people do on a computer?)

You really don't want to hook up your company's network storage to the internet; running a browser without domain credentials should avoid that, in a typical enterprise environment.

[Non-experts] mistakenly worry that software updates are a security risk. I think this betrays a lack of thought about the risks to non-experts. Tons of malware masquerades as legitimate updates, and non-experts don't always have the knowledge to distinguish legitimate updates from malicious ones. Therefore, to non-experts software updates are a security risk. Edit: And this is why Chrome's policy of updating automat…

With windows 10 they're doing forced updates for home editions, so there's that.

What should I use as a VM environment/OS? Obviously I know GNU/Linux distros, but if all I'm going to be doing is using Firefox, I don't want a 8GB+ VM file hogging space on my normal system. Right now, I only have a 256 GB SSD in my laptop, and have my VMs on an external hard drive, which when plugged in to use uses up 1 out of my 2 USB ports. I would love to browse in a VM if I could get away without using a ton of space on my SSD. Also if you have any suggestions for options that also support high-DPI, that would be great, but not strictly necessary.
