First excuse me for writing a lengthy review, but there are a lot of ground to cover. For those who like the short version, with less information is here: Norton slowed my DSL connection by a third party. I spent a day with Verizon, could not understand why all my other machines on the network received 756k, which has a maximum of only 4 or 500. Norton removed, and bingo, instant 756k. AVG Free Edition is beautiful but has a lot of time to start, while updates on every boot, unless you disable this option, then sends your Outlook e-mail with a message that your antivirus is not to date, and this message could be dangerous or something. Zone Alarm used to be the best, now on the verge of the worst. My Windows 2000 went after a blue screen update, took me 2 days to discover that the problem was, so it removed after discovering the problem in a forum, and it solves. ZA after also recommend to my friend, would not work at all on a Windows XP Media Center machine. Ask ZA and say they no longer count on the Media Center. 50 U.S. dollars down the drain. Now, take my regular XP SP2 edition and more than 5 minutes to start with Zone Alarm Security Suite, and I am referring to more than 5 minutes, is ridiculous. I removed the burden of McAfee Virus Scan (MVS), and the machine immediately shot just 2 minutes and 15 seconds to the point that I was able to take a page from Google. Therefore, the MVS load and start the machine in just 2 minutes and 45 seconds, once again a page from Google that appear. In both cases, I clicked on an icon Google Desktop as soon as it appeared, and then wait for the results. It clicks, is dark blue, and wait while the burden, including MVS before allowing a page to appear. Thus, MVS took only 30 seconds burden, and in accordance with Scotty in the WinPatrol watchdog, the burden on 7. Exe. Therefore, it is fast. Now, it is with a machine that is loaded with a ton of programs.
