In response to several warnings, I responded to my browser and mail provider. It's been a 12 hour on and off conversation with some guys in Delhi. They seem to know exactly what they are doing, and are polite with perfectly-grammatical if accented English. I am fairly sure one of the guys learned English from a Scottish teacher.
The point is that I had a few hundred attacks on my computer over 48 hours, some foiled and some not. Some of these evil programs penetrated my email and my laptop. Of course, nobody cares about my info, but I do not like roaming intruder programs, worms and all that, messing with my machine. Russians?
So the guys in Delhi sold me on a fancy new firewall and got rid of a lot of stuff that CCleaner could not. My old firewall was obsolete, about 4 years old. As readers know, it is a bit creepy the way the techies can take over your machine and do whatever they need to do. I guess you just have to trust them.
