Question: My understanding is I do not have to install Norton Virus.  Is this as good as the security that my Mac has been providing me these past 6 years?
Document: Sometimes it seems like it takes a while for something in my files that I've clicked on to come up. That's why I've only given it 4 stars. But I like the default sounds that they have installed on it. Love the variety of desktop personalizations they give you. I still haven't been able to find where the solitaire game is hidden on it yet (if it even has games installed). And this is the first time I've been able to install Java in years without any problems.
This is a good quality computer for a great price. This is the second Dell I've owned and I've had the first one for many years. I expect this one will be just as good.
I can't understand why, when using power cord, the screen is not nearly as bright as when I am operating on the battery mode. I am sure that it will straiten out when I get used to the new system. I am 93 years young so there is a good chance I am the problem and not the laptop.
I thought the price was good, but it came with Windows-8, and lacked a slot for the memory card.I paid to install Windows 7, and now my computer guru says &#34;It doesn't have very much 'power'&#34;. I'll have a friend evaluate this laptop. and may set it aside for one that is better.Even brand new, sometimes it's so slow, it seems like I've returned to dial-up!
Great computer, the only problem I have with it is there is no app's  install with computer to play my  DVD videos automatically.
I've had trouble with this computer from the start. There seems to be some kind of virus nobody can help me with....
I can't rate this computer because I spend at least 50% of my time deleting popups-some that regardless how often I push the X don't go away, I had a Windows Vista for several years and easily set it to block most popups. When I change the settings on this one it blocks sites I want to visit. It might be a nice computer, but the popups are so annoying that I hate it,
I am not sure who cheated me but I think it is DELL> Ten years ago I bought a Dell Tower with XP at the Dell site. It said I would get an A drive. When it came I could not add an extra drive to the inside, no place to put it even though the outside looked like there was space on their photo and no A drive even though it was on my description. Sending a computer back and forth in the mail is a pain. So I kept it.
Junk!! 2 Dells over the lastb 2 years the harddrive crashed. Both XPSs. DO NOT BUY A DELL!! And customer service is terrible! Unless you like curry!! !
Just what I needed. The old desktop is a dinosaur and just needed to upgrade. Getting used to windows 8, it's not too bad. Have had no problems with Dell products in the past, so decided to purchase this. Love it, fast, portable.
Answer: There are multiple excellent free antivirus options out there.  Microsoft's own Security Essentials is free and fast.  Spending money on Norton or McAfee is a huge waste.
