I do my work and communications on personal laptops. I have four of which three are currently working on System 10 and 7.

Query: I want to do a software 'teardown' on my most used laptop to clean it of malware and extraneous apps and cookies that have been installed on it over the past years, not all of them with my knowledge. While it works, it doesn't work particularly fast.

So I'd like to run a benchmark on it or if that is the wrong term a performance index program. This will allow me to compare it to new items on the market, but more immportantly it will give me something to compare to when I've finished the cleanup / reinstall of the system.

And, as a by-the-way, not that I need to know, but I'm curious, is there a cross platform method to compare performance of a particular PC using Windows to a PC using Linux or a Macintosh?
