As to HP's Health Check, what does it say that you're not protected? Is it referring to antivirus, firewall or security updates for your Windows?
You do not need to pay for Optimization tool for Windows. Windows have built-in defrag, disk clean-up and there is a better alternative:
CCleaner from http://www.ccleaner.com
I just got a new computer and am using a trial version of Norton 360.
My ISP is Comcast so I get McAfee for free but even for free I thought it was a horrible program and downloaded a couple of free ones recommended on Cnet, one I would leave on all the time the other I would leave off and just update and scan every night.
I also had System Mechanic but I got such poor support from them I am not hot on using them again. But do like PC optimization tools also.
It seems that Nortons program has gotten much better since the last time I used it, I like the updates every few minutes, the fact that it scans fast, and it has both the security against viruses and some PC optimization but not as many things as System mechanic, though I am not sure I need it system mechanic would defrag RAM for example.
I am willing to pay for the program if it is the best, but if there is something better I would like to know and use that. I also would like to know if the PC optimization with Norton 360 is comprehensive enough as it could be.
BTW I also turned on Windows Defender.
I have read that it is not good to have more than one anti-virus program on your computer but I used to have two loaded on and only one active then would shut that down and update and run a scan with the second one every night.
So what is my best protection I can get and is there a better optimizer than Nortons 360 has?
Finally does running Windows Defender count as running two anti-spyware programs that could conflice with each other or is it ok to leave it on as well as other things.
Even for free I would not use McAffee, it did not seem to ever find any problems when the free programs would.
Since I am moving from a 5 year old computer to a new one I am happy at how much faster and better my computer runs and also how much Norton has improved their program, but I dont know if there is something either better or that I should also use for full protection.
I have an HP computer and in the Health Check it tells me that I am not protected for the Internet even though I have Norton and Defender running and the firewalls on. I have tried to run the scan again and it still says I am not covered for online threats but the Norton programs says that everything is just fine and it does find things when I run a scan and it is much faster than the old program, but it could also be I have a faster computer. I am running Vista Home Premium 64 if that makes a difference, so far I have not had any problems with this OS at all and since I used to use XP it is similar enough to not need to be told how to use it.
Thanks in advance
