• Russ Cooper's NTBugTraq. Russ moderates two independent Windows mailing lists: NTBugTraq and NTSecurity.
  
  
• Sygate Security Scan. This service will port-scan your computer from the internet, so that you can see if it's publishing any unwanted services. Then consider installing personal firewall (or just use the one in Windows XP), but bear in mind that it won't protect you from malware in email or on dodgy websites.
  
  
• SysInternals Techie info and some nifty utilities. Formerly Sysinternals.com, but recently bought out by Microsoft. Let's just hope the men in suits don't delete the good stuff.
  
  
• BootPart from WinImage Stuff for messing with partitions and boot sectors.
  
  
• TeraByte Unlimited. BootIt Next Generation offers a free download that boots off a floppy, letting you resize partitions and (optionally) install a Boot Manager. If you keep the Boot Manager, you have to pay for it after 30 days.
  
  
• Wireshark The excellent network sniffer/analyzer, formerly known as Ethereal. Runs on Windows, Linux, MacOS etc.
