If you have a multi-user subscription, you should be able to load it onto other computers at any time during the period of the subscription, and the clock starts ticking when you load the first one on. I have a 3-user subscription to Norton anti-virus and I loaded one right away, and another 6 months later. However, I have the disc. Since you downloaded yours, did you save the program on the first computer? If so, you could make a copy on a flash drive, and plug that into your netbook and install it. If you don't have that option, you should go go the Symantec web site. When you put the program on the first computer, there is typically a registration step that establishes an account at Symantec. Each time the program is installed and registered, the registration process takes you to the web site and the number of program installs is kept track of in your account. If you log into this account right now, it should show that you have two installs left of what you bought. If you don't have the program, and/or you can't remember how to get into your account (or can't retrieve the info), call Symantec tech support and explain the problem and they should be able to walk you through this. It would probably be helpful if you had your online receipt of the purchase handy when you do this.

I believe Windows Defender is integrated into the OS and couldn't be uninstalled even if you wanted to...unless of course you were willing to risk damaging something else. If you launch Defender manually, you can click TOOLS>>OPTIONS, then scroll to the bottom and uncheck the box marked USE WINDOWS DEFENDER if you want to disable it. I don't think it will conflict with avast! but would be very surprised if it finds a bona fide nasty that avast! does not.

wait you don't have to take those off just turn them off while you try to get AVG to install and work. They are all fine good programs and should be on the pc. I would bet some of Norton may still be hanging in there causing the problem, so definitely use their removal tool for the version of Norton that she had that should clear up most of it. then go to right click start then explore in the tree> program files see if there is still a folder for Norton if so delete the entire Norton folder, anything you see labeled Norton or Symantec should go. You did not do anything wrong sometimes things just have conflicts and especially with Norton. So do the removal of that then just turn off those programs and try AVG again. The reason I suggest using the method in the AVG faq is that it keeps it from installing some of the extras that have caused problems on some pcs. It is a much slimmer version. You are doing a good deed! You are helping someone ,that is always a good thing. As I said it may require doing an add remove on AVG then reinstalling it, that is why it should be disconnected from the internet since you will be with out protection while AVG is not working. If AVG continues to fail you could try AVAST free, I use it on one of my pcs. avast! 4 Home Edition - FREE antivirus the install and user guide are on that same page off to the left. I do not use Vista so if anyone is aware of any conflict issue that I don't know about hopefully they will let us know.

AVG (from Grisoft) is an excellent free antivirus and they have a more robust pay version available. I prefer it to Avast, but it's good too. Avira AntiVir has a loyal following too. There's a lot of free programs out there and in reality, if you keep them updated and use them properly, they'll all serve you well. McAfee is, well, McAfee. I wouldn't use it on a bet. That's one that I've had so much trouble in the past that I wouldn't use it, but in fairness, I haven't used it in years so they may have changed. Norton still is a fine program but it's not as user friendly as are a lot of others. People with limited computer experience don't understand it and that causes a lot of trouble. Historically, amateurs liked McAfee and pros preferred Norton. I quit using Norton about 7-8 years ago. Been using AVG for 10+ years on various machines. It's standard equipment on all machines I set up and has been for a long, long time. Now let's clear up some myths. Especially this one about Norton taking over your system.... Did you know that's for your BENEFIT?. Many viruses, spyware and malware programs will go in and turn off your anti-malware programs. By having it deep in there like that it helps to prevent that from happening. The ones that chant conflict seldom know of what they speak. For many years I ran 3-4 antivirus programs, just not all at the same time. When I was with the PI firm and handling a lot of sensitive data I couldn't risk infections so I'd run a minimum of 3 AVs on any attachment. Anyone that says only a tech can remove Norton is full of crapola. Period. But it makes for good gossip doesn't it? With McAfee and Norton both, you simply run the removal tool you can download from the manufacturers' web sites and it's pretty much automatic. Far worse is the way AOL embeds itself into a system. Or at least how it used to worm its way in. That program did truly approach a virus-like embedding. And the fool that says you can't get malware from dialup? Spray her in the face with a water bottle and ask if she's been eating paint chips! Totally untrue! An antivirus is only one part of a layered security approach to maintaining a safe computer. You should have a good firewall and I like Comodo. One of the easiest and most effective ones out there. Don't forget to get Windows Updates regularly. Especially if you use the swiss cheese of browsers and mail clients - Internet Explorer and Outlook/Outlook Express. You're begging for trouble by using them but many refuse to secure their systems. Antivirus has been covered. Keep it updated. Anti-malware. Malwarebytes is one brand of antimalware software. I prefer Spybot Search and Destroy and A-squared but I keep Malwarebytes and SuperAntiSpyware on my machine for an occasional backup check. Ad-aware used to be my program of choice but I stopped using them a few years ago. Ccleaner is an excellent program for cleaning up your machine and Iobit's Advanced SystemCare is an excellent program for both cleaning and tweaking your system. WinPatrol is an excellent program to guard your system. It'll tell you when things are added to your startup, changes made to your browser and more. Another important thing is use common sense. Don't believe everything you get in an email for one thing. Any important documents should be backed up regularly in a variety of forms. That way if you have one bad backup you won't lose everything. I don't have sympathy for people who keep their entire lives on the computer and then lose it to corruption or theft. Again, common sense. You should do disk checks, clean out temp files and defrag your machine often. All this helps keep a machine performing better. If you use Opera and customize it, you can back up your settings with Operafly. Firefox can be backed up with Mozbackup and FEBE. Any program with a built in backup, should also be backed up regularly if it's of any importance to you.
