once in Tunisia a village hairdresser proposed to massage my head with it... I had to tell him all tourists aren't fools
Panda 2016 AV Pro bricked my rig, locked system partition I had to make a clean install again, never trust Panda.
I opted to use Panda and the other bits and bobs but found Panda to cause far to much problems from crashing system etc... so trying out 360 total security, pleasantly surprised so will stick to testing this for a while.
A word of warning to those trying one security suite after another. These things get so deep into the system that you wont get rid of every trace, say security suit number two or number three is a complete turkey, is it really? Or is your system so full of rubbish from the first and second installation that your latest choice is unable to function correctly? A system refresh or re-install is the only sure way to cleans your system of some of the AV software on offer, the cleaning tools these companies provide vary from useless to just about acceptable. Can I suggest that you do your homework and only install the AV you are going to stick with. I am using Avast [free] but I would not argue with those who choose to stick with Windows Defender, its already there and its free.
personal choice, backup often, save hard drive read times. Things like ransomware become no big deal this way
