|During the installation of Windows XP, one of the screens mentions setting a password for an account called "Administrator", but this account doesn't require a password (security risk!) and people often skip through installations with out reading the screens. A few steps after that is when you create your everyday user account (again no password required) that has administration permissions.|
After installing Windows, make sure you install all the appropriate device drivers (particularly motherboard chipset, video, sound, networking) and get a real-time anti-malware program like Avira Free or Microsoft Security Essentials. In addition, download/install Malwarebytes Free or SuperAntiSpyware Free, or even both for even better protection. The free versions of Mbam and SAS are on-demand, so they'll only scan when you tell them to. Update, then perform quick scans when them once a week, and full scans with all your anti-malware programs (not at the same time, of course) if any of them ever detects a threat.
SAS will detect and remove tracking cookies which aren't necessarily malicious, but a good thing to remove anyway. Don't be alarmed if it finds many tracking cookies.
