    Very nice. One thing I don't like, is that I bought protection for 3 PCs, but I had to give the same Windows Live ID, which isn't a very good option, since I would be giving my friend my hotmail's password. But we found a way around it.

    quite good AVG is better in my opinion, it detects viruses well, although even when the trial is up it will keep promting you to subscribe
    and i'd rather just use avg than subscribe

    Microsoft done alright for once (Y)

    Easy to use, and simply the greatest software for your computer. It protects your computer from 99% of viruses out there. I'm only saying 99% so I can leave a margin of error... but this really is a great tool and a must have.

    Using it for a year and a half now, great stuff. Helps me manage the security and backup of my parents computer, who live elsewhere, as well

    Best AV suite out there. First thing I install after a Windows Install. Easy to use and light on system resources. 'nuff said.

    OneCare really rocks. Easy to use. Simple Interface. Light on system. Tough on rogue. Kudos to Microsoft.

    I had this program for 1 year after Microsoft gave it to me for £10 for completing their beta testing of the application.

    It does detect threats really well and doesnt use many of my system's resources

    but

    This program FAILS wayyyy too much, this is why ive moved to using windows defender with AVG antivirus and Windows firewall, which together provide me with the same level of protection using roughly the same amount of system resources.

    What I hate about this program is that on one of my computers the firewall part of the application wasn't working and on my laptop the antivirus wouldnt start with windows. I spent over 5 hours on the phone and on remote assistance with a Microsoft support technician who was unable to fix any of my problems.

    Overall I feel that this program has a lot of potential, but Microsoft must sort out its reliability for it to be successful.

    Honestly, this is better than nearly any other anti-virus, anti-spyware, firewall, all in one optimization program available. It doesn't clunk down your system, it runs silently in the background, and alerts you when needed. If you need one, and don't mind spending a few bucks, it's the best!

    I find this program great, doesn't slow down my machine and does the job. Have recommended it to other people too.

    Just finished installing v2.0 beta on four computers...2 Vista Ultimate, 1 Vista Home Premium, and one XP Home. There wasn't so much as a hint of any problems.

    Overall:

    Have been using this product since it first came out in beta. Have not had a single problem...it sits there quietly has does the job extremely well. It was recently awarded the VB100 award from Virus Bulletin. This award comes on the heels of OneCare’s recent re-certification from West Coast Labs and the ICSA Labs.

  • FreshRob devotee

    2.0 is actually quite good, it doesn't slow down my system and the 1year free subscription thank to the beta serial code can't be bad
