I installed this software several weeks ago. Worked fine for about a week, then one day after rebooting, message came up and said I was unprotected because my firewall wasn't on. I could not 'change' the setting. Read all the instructions that Windows Onecare gave me, nothing worked...nothing. After much frustration, I disabled Onecare, downloaded AVG Virus program, ran a scan and it found 27,000 virus's and 79 spyware on my computer. Onecare did NOT catch any of this at all.
In my opinion, Onecare is a piece of *** I wish I hadn't paid for. I highly recomment AVG, it's free, has caught all my virus's and cleaned them, has removed all the spyware and Onecare won't even work now (after spending $59.00).
