I've used Download.com also for years, and the affiliate Cnet, and was surprised to hear it rated lowly as a security risk .A lot of downloads from Microsoft , utilities etc. re-direct to it as a download site.
Cnet have free online courses, I did one on Anti-Spyware last year , and asked the "teacher" why am I getting all these
tracking cookies when I login to do this course (?) . He replied they were harmless advertising collection data . Really quite funny, as we were learning all about Spyware, and they were spying on us
, . Good Free Courses at Cnet actually .
