- I check the location for any cameras that may record my screen
- I make sure I have administrative rights, otherwise I'm going on to the next place.
- I use task manager to check for the obvious viruses
- I plug in my USB drive to get access to all my tools.
- I execute my script to kill all user processes.
- I manually check how well that worked and kill the remaining application.
- I shut down all third party and non-essential Microsoft services, I really should write a script for this too.
- I run the www.sysinternals.com RootkitRevealer to find any root kits, which are not visible to the Windows API or Anti-Virus software. This takes a while to run and you have to look at the results carefully.
- I use Firefox to connect to my bank's site, never use IE, it's much easier to track keyboard and mouse clicks in Internet Explorer.
- I double check that I'm using SSL/https and that the certificate looks okay.
I would say that I'm now possibly more secure than many workstations within Microsoft, just look at all the stuff those guys are having on their laptops during presentations.
