Norton Internet Security: No installation issues, inexpensive, functional, and still no viruses in 10 years of use!I've written reviews in the past on Norton products. I personally, have never had any issues installing, uninstalling, reinstalling, or upgrading any Symantec product. I know that they happen and I feel for all those who have had issues. I know for many in my family who have had issues that I've had to rectify, the majority of the problems arise from installing Norton over the top of a different (or even other Symantec) security/antivirus software package.The first thing you need to do before you install this software is go to Add/Remove programs in your control panels. Remove all of the 3rd party security software you have installed (any Norton, Symantec, McAfee, Panda, Kaspersky, etc). Then Restart. You may need to restart more than once as directed by the software uninstaller. Following this procedure I have successfully installed this software without problem on more than two dozen of my own computers and probably more than two dozen of my family's and friends' computers. This seems to be one of the most complained-about issues in the other Norton Reviews.Second, price. You can pretty much always get Norton almost free. There are always twenty dollar rebates for upgrading. All you have to do is send them an old Norton (or other antivirus software) CD or box top. If you don't have one of these you can usually buy an old Norton or other security software cd on ebay for under $5. There are other rebates usually available as well tied in with Turbotax. I think this year I actually got paid $10 to buy Norton Internet Security Suite 2007 - 3 user suite. I split the 3 user licenses among other family members making it an even better deal. The 3-user package is priced almost the same as the single user package, so make sure you buy the 3-user package.
Thirdly, while the software does indeed slow the computer down, I rarely am annoyed by it. The only real problem that I have had that makes me drop my rating from 5 to 4 stars is that the process of downloading emails into outlook is slowed down quite a bit as it doesn't move onto the next message until the previous one is totally scanned. I have noticed an improvement in the functionality of Norton software since 2005 when it was particularly bloated, but still functional.
Finally, and this is the gold standard for any review I will write of an antivirus software: I have never gotten a virus almost 10 years of having computer and running Norton products. This is more than many of my friends and family can say who have tried to save money or mildly boost computer performance by going with a different package. I don't know if I can attribute this to Norton or just cautious internet use. But I do know that my computer and those computers of family members that I maintain who have had a never-lapsed Norton Antivirus software package installed have NEVER gotten a virus that was not immediately detected, quarantined, and repaired or removed. That is why I will continue protecting all of my computers with Norton Software.
