I try to avoid the seedier portions on the 'net
However, I'm constantly researching and so can't avoid everything plus I do most of my shopping on-line, although from the same places and they're all good.
I don't really know what Linux is or what to do with it if I had it.
I had Ad Aware on my computer but when I got the virus a few months ago and Dell cleaned out my computer, they uninstalled Ad Aware telling me that it wasn't totally compatible with McAfee. My free Ad Aware hadn't operated correctly for some time anyway. I never could get the damned thing to update correctly.
