Of the 31 papers not written by El Naschie in the most recent issue of Chaos, Solitons and Fractals, at least 11 are related to his theories and include 58 citations of his work in the journal.
And it's actually a theoretical-physics journal, with a relatively high impact factor of 3.025 for 2007.
There are solutions for each one of those circumstances:
1. You never open links in search results to sites you have never been to? - If you are running windows using Firefox or IE there have been many cases of 0 day exploits
Run your browser with lower privileges (even if you are a not an administrator, which by itself thwarts most of the virus, which expect otherwise, run it with a constrained token). See http://blogs.msdn.com/nigelwa/archive/2005/07/29/445155.aspx. Additionally, IE7 protected mode under Vista has an excellent record.
2. Do you not use any USB storage devices? - Just this Christmas I purchases a digital photo frame for a family member that had built in storage. low and behold when I went to preload it with photos it was already infected with a virus that was set to use auto play to install.
This one is straight-forward: just deactivate auto-run.
3. You 100% trust EVERY thing your friends or family send you? Document infections are still somewhat common. I suppose using Open office would get you around macro infections but you also might not be able to open company documents then.
This may be a bit more problematic, but macros are usually not set to be run by default. If you are paranoid, you can always run Office apps with less privileges.
