Unless there's a site that absolutely needs it for form entries or some other script based function - DO NOT, repeat DO NOT USE EXPLORER! (It's like putting a key to your house hanging on the front door.) That's how all the bad crap gets on your 'puter. Only use Explorer if there's a form or some script at a site that is necessary to use (such as a bank or govt. services), and only use it at trusted sites that you've visited before. For casual browsing and surfing the net, use a Mozilla based browser. This way you can disable popups w/o having to install any more software, and it will not execute any malware. Also Mozilla will let you know if it does start a download for some reason, and this always has the option to cancel. Also be wary of some types of free software. Usually the P2P type programs are bad this way. Unless it's open source or from a trustworthy site, they're likely to host trojans and crap up your computer.
