What our customer's say!

"A great program", When I first started to use this program (this is my 3rd year) I was told by my computer literate friends that I would be sorry. The word was that Microsoft couldn't write a good error-free program. Well since then they all have gone to One Care and feel that it is by far the best there is out there. If like me you want a program that does it all and keeps on top of everything that needs to be done when it needs to be done then this is definitely the one for you. Not long ago one of my machines (I have three that are protected with the one program) died and when I plugged in a new tower, went on line and then to the One Care site it found the program (from points on the monitor is my best guess) and brought my new machine back up without a hitch. Now that's service.

"BEST", If you go right now and ask any stores like best buy,that which antivirus is best they would tell you one between these,MCAFEE-NORTON-PC CILLIN,but i am a computer technician,i tell you that non is like Microsft antivirus!since i am working with internet a lot!before i used to change my widows everymonth becuase of virus!but now no more!i have my windows for 1 year!also i installed this for several people and they always appropriate me!just think about it for a minute!who made windows!microst!so wow knows better about windows and can make better antivirus!microsft!trust me!go to [...] and get 90 free trial!I am sure you will never go with anyother antivirus!

"Great Product/Awasome Price", Great product. I am using it for second year. Have been very satisfied with OneCare and decided to continue with it. The price is amazing especially this time. I got it from Amazon market place for $5 because it is an old version but this does not matter. All you need is the subscription key and you can get the latest version online unless you already have it as in my case (I was renewing my subscription).

"OneCare will never completely defragment your hard disk", I just bought a new laptop with OneCare 2.0 preinstalled. My system is much faster than when I used Norton and (so far - 1 month!) I have been mostly happy with it. However, I noticed that the weekly tune-up kept coming back with a message saying "C:/ Defragmentation partially completed*. Because of high levels of disk fragmentation, starred volumes could not be completed in this Tune-Up and are marked for defragmentation in later Tune-Ups". I presumed this was because my computer was new and I had recently installed lots of new programs so I ran the defragmenter included in the Vista operating system which took a few hours but did the job. I then immediately ran a tune-up through OneCare and the defragmentation came back as being successful. However, 2 days later (during which time I only used the computer to check my email), the automatic tune-up returned the same message of "Partially completed... High levels of disk fragmentation...". After connecting with a OneCare representative via chat, I was told that the defragmenter would never complete the defragmentation process. To quote directly from the chat: "...as for the tune-up process on OneCare, it really doesn't complete the tune-ups." and "In order for you to complete it, you have to manually do that defragmentation on your local disk." In answer to my question of what's the point of including defragmentation in the OneCare program then, I was told: "As part of the tune-up process, and since OneCare is only sharing some services of your Vista, it doesn't complete it.", which makes absolutely no sense to me! Obviously, the defragmenter is included for free in your OS but if OneCare says it will automatically defragment your computer during programmed tune-ups, it should do this 100% every time, especially if you just did a complete defragmentation two days ago. As I say, apart from that, I have not (so far!) had any other problems but I now understand the paranoia in relation to Microsoft.

"Very happy with OneCare", I was fed up with Norton so when my husband asked me buy anti-virus software for his new laptop I knew it wasn't going to be Norton. After reading the reviews here on Amazon I decided to try OneCare.

We like it so much that we installed in on new desktop, as well.

I haven't had one virus and I like that it let's me know what's going on with my pc while I'm online.

"Windows Live OneCare", I have used this product for three years and am very pleased with the results. Microsoft Windows Live OneCare 1.5 Online PC Care Subscription [12 Months]

"So far, so good", I originally used McAfee on my Vista-equipped laptop. After many software and stability problems and an eventual hard drive reformat, a review of various message boards suggested that Vista stability issues were often related to overzealous anti-virus software. I installed the free trial version of Windows Live OneCare, assuming it was more likely compatible with Vista since it was also a Windows product. So far it works well and is less intrusive than the McAfee product. The hard drive scans and update downloads do not interfere with normal operations or slow the system as McAfee did. And the auto-backup works seamlessly as well.

I don't normally recommend Microsoft products, but this one works well and is a good value. It is less expensive that other alternatives, only $50 for a one year 3-user license. However, you can usually find it advertised for $10-$20 at the major electronics or office supply chains. Try the free 90-day trial at the Microsoft Live OneCare website.

"Warning: Your computer will crash after installing this product!!!", I liked the idea of having an all in one security software so I went ahead and installed this product. What a mistake!!!. I had been using AVG antivirus for a while without any problems but I wanted to have the firewall and backup feature. Everything went OK till I tried to shut down the computer, I got a blue screen (and you know what that means) and waited 10 minutes, finally I had to turn it of using the power switch. I rebooted the computer and it worked ok, I tried to do a system restore and guest what, the computer did not restart, yes; the blue screen again. After spending several hours trying to make my computer work normally again I gave up and went to bed at about 6:00am, later that day I had to reinstall windows XP again and lost all my data, lucky for me I had a backup and recovered most of it. Now my computer is working and I switch back to AVG after spending three days and lots of Tylenol for the headaches, so that was my experience with Live Onecare. DO NOT BUY THIS PRODUCT!!!.

"windows live Onecare is awesome!!!!", awesome anti virus by Microsoft..Work's great on vista,it work's automatically and quitely. although if your not sure just try the 90 day's trial first. I reccomend everybody to buy this software..I been using it, and I dont have a problem with it...I'm completely satisfied with this product.."hint: DO'SNT WORK ON VISTA 64 BIT"

"Live OneCare Just Ok", Microsoft's LiveOneCare (LOC) seems to be a good solution for "all-in-one" protection. I switched to this service after experiencing feature bloat and general slowdown from other anti-virus/anti-spyware suites. It runs pretty much in the background, staying out of the way of other applications. Just make sure to schedule the "tune-ups" away from the time you need to do other things. The virus scan is pretty slow - effective -?? can't really tell, but my machine seems to be malware free at this point. The software is still a little rough around the edges in places. There are very few parameters that can be adjusted to personal preferences and some of the report results are a bit obscure. I like too much information rather than "sparing me the details." LOC has pretty decent support from a users forum on-line but not much help from Microsoft itself. A couple of bad update patches caused grief for a number of users during mid-2007 but those seem to be resolved now. Overall - not bad - I am staying with LOC and would not hesitate to recommend it to others.
As a nit-pick - I don't like Microsoft's new software packaging. It is a hard plastic box that presents an interesting challenge to open the first time it is encountered. Much too big for a single disk - hard to store. Hopefully recyclable material :)
