I'm interested to know what people do to keep their system secure, other than installing an anti-virus package. I'm asking this as although it is possible to keep a system secure through taking plenty of sensible precautions, it's hard to stop being compromised via vulnerabilities.
I've run anti-virus software for many years now, and it mainly seems to detect e-mail virus attachments which I wouldn't open anyway. However, once it found a trojan on my main system which I found it very difficult to trace. It turns out I was using an insecure version of Adobe Acrobat reader... this started the problem as I ended up visiting a blog which had been hacked and had some iframe code injected in to each page. The iframe contained a PDF file which exploited this vulnerability and somehow contained a trojan payload.
I don't know how serious the trojan actually was, as by the time my AV scanner recognised it a few days later there was no information available about it (as it was so new). Taking no chances, I just formatted and started over - as it gave me a chance to have a spring clean.
This was a long time ago now, and since then I used tools like Secuna Vulnerability Scanner to make sure all my applications are up to date (and I've switched to Foxit Reader instead of Adobe, as any vulnerabilities aren't often exploited in that).
I'd be interested to hear what precautions people here take, aside an anti-virus package and common sense. Do you use other tools or perform manual OS hardening?
