You can't say I don't know what I'm talking about when I have a client who had these pop-ups and the computer ran very slowly, but installing Linux on the computer made it run much faster, and there has been no further complaint about pop-ups, even though the client's browsing habits haven't changed. And yes, I know all about that CCleaner mess. It misses a lot of obvious stuff, just like all the other crap they put out there, expecting us to wrestle with our computers trying to get them to work properly with this easy fix and that easy fix that just makes the problem worse. And actually, CCleaner was one of the better "easy fixes," even though its best feature was just removing temporary files. I never noticed the claimed speed improvements and performance enhancements that were supposed to come from letting yet another little cleanup tool do its thing, probably because the Windows registry is a huge thing that is very hard to clean completely, and one wrong move can make your machine completely unbootable, whereas in Linux, if I get bloated configuration files due to multiple upgrades and such, even if I just go in and rm ~/.??* I just have to reconfigure my settings again, because all the configuration files recreate themselves from defaults, and I'll never have an unbootable system that way. Let me just say that I know enough about Windows to help people find better alternatives, and I know enough about computers in general enough to help people find alternatives to broken and outdated software. And yes, I know enough about Linux to help people find alternatives to broken Linux software also. ~Kyle http://kyle.tk/ -- "Kyle? ... She calls her cake, Kyle?"
