Pros AV, ASpyWire, Backup, Tuneup, Sharing, Circles, Family Controls...
Cons You lose all settings when upgrading or reinstalling
Summary The new 2.0 version of Onecare really adds to an already strong 1.5 Version. In this version, you can now manage multiple Pc's as part of your circle. I'm able to review status of computers in my circle from my laptop plugged in at work! In addition to AntiVirus, and AntiSpyware, supports backups to centralized network storage, optional online photo storage, performs tune ups, patches, file cleanups. Just noticed they added Family Support, which is an optional and free add on to monitor and control child usage of systems. It really is paying for itself in all the add ons!
Pros Cheap - reminds you to run it.
Cons Does nothing well (defrag or backup anyway)
Summary I bought it on sale for $9.95 which is dirt cheap even for 1 PC and it can be used on 3 for a year. The problem is that it's clumsy, slow and you have virtually no control over backup and defrag. I only installed it under Vista (where I have little to lose) because I had heard the 1.x release was awful but 2.0 was better. Think about this: to run a "tuneup" you have to let Onecare complete a sequence of spyware scanning, defrag and then backup. In my case the defrag will run for hours so I can't backup Vista unless I'm willing to sit thru a full (and slow...) defrag - it's just stupid... The backup applet does not seem to integrate into a full system restore that I can see so it's just a file level backup and you have crazy choices like "mail files" and "financial files" which are based on extensions. This might be better than nothing for somebody but I think most people would be better off syncing to a USB key and doing the rest by themselves.
Pros This was simply the best. However Microsoft is ending it and replacing with a free Suite...
Cons The end of onecare nears.
Summary Microsoft has introduced MICROSOFT SECURITY ESSENTIALS which will be taking over onecare and will be FREE so do not buy onecare.
Pros Ease of Use, Smooth Operation, Very Helpful Feature set
Cons The only con I have is that it may be going away.
Summary I purchased my current PC brand new from HP in March of 07 I believe. I was originally running Zone Alarm Security Suite however, it was not ready for Vista so I gave OneCare a try. The result is that I dropped Zone Alarm and purchased OneCare and never looked back. I have to admit that I was doubtful that Microsoft could pull it off but I'll say that Live OneCare is the FIRST Security Suite that I have owned that ran so well that I don't notice and even forget that its installed.
After the first month of operation I was constantly checking to see if it was operating because it never seemed to get in the way or show any signs that it was scanning or downloading updates. Granted I always run scans and updates when Im asleep but even with some of the highest rated Security Suites out there the strain they put on your PCs performance is beyond noticeable.
I have pretty good web surfing skills so I tend to block a lot of things for getting placed on my PC.....even cookies from sites I don't know so even after having OneCare for two years I was surprise and kinda excited that I had finally bumped into a site that try to download something malicious to my PC and OneCare stopped it in its tracks.
The reason I was excited by this event is because the program runs so quietly that I often wonder if its protecting me at all. At one point; after originally installing OneCare after eight months I uninstalled it and installed Zone Alarm, ran a complete scan of my system and found that it was clean.
Of course I removed Zone Alarm and reinstalled OneCare and have been fairly confident that its doing its job and doing it well.
Pros Very Light, Nice UI, Fast, Backup, Tune-up, Low Price. control 3 computers.
Cons None. Everything is a pro about onecare.
Summary Worth the money.. get it for 29.00 at walmart.I highly recommend OneCare but I would not purcahse it right now. Microsoft has began phasing it out to make room for "Morro" The FREE antivirus in windows 7.
