jerryc41 has a good point and for that reason i use windows 10 on line but a different computer with xp for my apps. If you play on line or cannot afford two computers then a fresh clean load of win 10 is your best choice. For those limited to xp i have found Kaspersky anti virus easy to maintain and effective for the past 4 years.
xp is a great operating system, simple enough for us non geeks to use and interface. I'll take it anytime over this stupid bloated window 10 anyday. You can have your swipes, pokes, and connectivity; all i want is a keyboard and file structure I can arrange to my desires, an operating system i can talk too.
There once was a time when cars were meant for driving and youth was ours to spend. I'm not sure which of my two girls i loved more... 40 years has not erased the pain of their loss...
