I have Secunia on my Acer Windows 8 laptop. According to latest scan today it's telling me I need an update for Microsoft XML Core Services (MSXML) 4.x That I don't understand since I've updated the laptop every time updates have been offered unless Microsoft failed to send it. (However, I haven't undated to Windows 8.1 yet -- I always hang back on that kind of major update to see what happens with everybody else.) I might be savy about a heck of a lot of things to do with computers but I don't know anything about that particular program. I started to read some stuff on it on the net, however, there's so much disagreement on it I gave up trying to figure out what to do. I hope I can get some good advice on that issue here. HELP!
