I tried Superantispyware on my mother’s computer (ME). Although I don’t find it particularly user-friendly, and mother found it incomprehensible, I would definitely choose it over a-squared. But after a few months, it stopped working, just wouldn’t open, maybe due to limited memory (the minimum required by Superantispyware) on that computer. Superantispyware requires 300 Mhz CPU or above, and minimum 128 MB memory. I’ll probably try it again after the next reformat.
