When should more memory be added to a computer?Can the same antivirus software be used on laptop and desktop?

Answer 1

Memory-
More is generally better, but there can be economic factors as well. If you need to improve performance on an old computer, this is the best way.

Anti-virus-
I assume that you mean you have purchased one copy. It is generally not legal to use on more than one computer. The very best antivirus programs are free though-

Spy-ware, etc: Ewido.com, ad-aware (www.lavasoft.com), spybot search and destroy (www.security.kolla.de) Google a websearch specific toolbar too.

Anti-virus, there are two free ones that are superior: www.grisoft.com has AVG, and www.free-av.com has avira anti-vir. You can only run ONE anti virus at a time, but can run multiple spywares. Download and install these programs, and boot your computer to safe mode (hit f8 on a re-start BEFORE windows comes up). Run them from safe mode. Good luck.

Answer 2

There is no such thing as too much memory. Add it at anytime and the sooner the better. You won't believe the difference that it makes.

Yes, you can use the same kind of software on both types of machines. You are supposed to have 2 separate licenses if you install it on 2 different computers.

Answer 3

First question: When your computer begins to take a long time running applications, when it freezes often.. I say if you check your current memory (Right click My Computer and go to Properties) and it is less than 512MB, you need to upgrade.

Second question: Yes. Just copy the setup file to your second computer. Or, install using the disk. You can use the same serial number for a limited amount of times I believe, but it can be done.

Answer 4

You'll have to check with the manufacturer before just adding memory. It depends on your machine. Antivirus can most certainly be run on both (same).

Answer 5

If your Laptop or desktop can take more memory then add it...there's no such thing as too much memory...and yes you can use and antivirus program for both laptop & desktop...
