    What can I say? Last recovery was about 2.5 years ago, and my system has been healthy since then. Maybe it wasn't as nasty a virus as all that.

    FWITW I use Avast and Malwarebytes, and I have never ever had a virus, spyware or malware of any kind. Also I do not visit questionable sites. But I understand that there are effective removal tools for TDL4 and similar.

    I think I wasn't clear enough on what my point is: Just because you don't experience any symptoms (anymore), a system is not necessarily clean. Malware is clever enough to hide and anti-malware software is not perfect; and on a compromised system it potentially is useless altogether. And TDL4 is just one of many, many examples – just look at recent news on what stuff is floating around and how it manages to breach even highly secured environments.

    Nowadays it is a misbelief that every malware can safely and easily be removed with a simple tool. It might or might not be enough, but the tricky part is that either way, you won't know for sure. It's not that I don't trust the software, but I don't trust my infected computer to run that software the way it is intended to be ran once it is not under my control anymore. Malware, that was "good" enough to bypass my security on a clean system surely might be good enough to bypass it on the system it now controls.

    So please don't take it the wrong way – I just meant to give a little "warning" that there are in fact very good reasons to format (and even more than that) the entire hard-drive upon an infection.

    By the way, Philip, I don't visit questionable sites either. Unfortunately, even pretty common websites act as infection sources these days, for example through ads or downloads. Look at all the popular websites that have successfully been attacked just over the last few months. Or how tools used by server administrators got infected at the place of distribution. And many servers are not completely up-to-date in their software, which leaves many security leaks open that can be used to infect every website running on that server, for example.

    I am sure that you know what you are talking about. I admit that I don't really as I have never had a virus or malware infection. But your suggestion to reformat my hard drive is not practical. My computer is an HP which came with Windows pre-installed and without any O/S disks. In any case the task of reinstalling and reconfiguring all the software is far from trivial.

    I have not the slightest reason to suppose that I am infected with a nasty disease. Same goes for my computer. I'll continue to put my faith in Avast and the integrity of sites (such as Coding Forums) which I visit. But I do agree that constant vigilence is required. At the same time I do not pay excessive attention to scare stories.

    My policy is to paint the fences around my house bright green in order to keep the tigers out. If you say that there are no tigers roaming around here, my retort is that proves how effective it is.
