If you've come from dial up to broadband and not beefed up your security, you would do well to check for intruders and plug up a few holes. Run the AV and malware programs suggested over and over in these forums. Invest in a router with hardware firewall. Most importantly, avoid the dark corners of the web that will be luring you in at this higher speed. Hope that offers some insites. Fast cars need better brakes than slow cars.
