I wouldn't touch panda with a ten foot barge poll it's use less I had it on my system ages ago and it let in a nasty virus that destroyed my system. Not to mention the pop ups from it every so often can be mighty annoying.
Microsoft security essentials is a good bet too, and its free
A few things to consider, you can get free av protection from microsoft for use with w7 - microsoft security essentials it's called, seems to work fine for many people. http://windows.microsoft.com/en-GB/windows/security-essentials-download
Also worth checking what the isp provides, some provide excellent av s/w at little or no cost, e.g. Virgin supply the excellent f-secure.
Thanks Mandy! Doesnt sound good.
I have that on my system, didnt realise it was available for download, i thought it was a preinstalled job.
They used to offer McAfee free for 12 months, don't know if they still do.Thanks for the link. There bb is with sky, as is ours not sure if they offer anything.
for free software I would go with avast and zonealarm. If you want to pay don't renew Norton via the software, buy it new from Amazon for £20 for 3 PC's for a year.
