Frankly, if it's on TV, you should not try it.
We've all seen them....programs advertised on
TV, often late at night, which promise to speed
up your PC many times, etc. This summer and fall
has been especially loaded with such ads,...
I would like to see how many have actually used them,
and whether you think they actually -
A. Helped a great deal
B. Didn't help at all, and maybe made it slower, or
C. Messed up my machine to the point I had to re-install.
The program seems to have installed a virus I couldn't
get rid of without doing a re-install.
