Knowing that MS will not update XP after April 8, 2014, how do you keep XP secure? I've heard that exploits found in later versions of Windows might also pertain to XP. With MS not patching XP, those vulnerabilities, if they indeed are in XP, will go unprotected. I'm wondering how effective protection supplied by Malwarebytes, Avast, ESET, etc will be at protecting against attacks on XP vulnerabilities. Has anyone heard any news on this angle? I'm asking because I have several customers who are still on XP. Actually, most of my customers are still on XP. Many are elderly and will have a hard time adjusting to anything. I have some business customers who will feel strapped if they have to purchase new equipment.
