Programmes like mcafee site advisor etc?

show sites as red or yellow if they are of "dubious" nature

ie:adult x sites and some video clip sites similar to youtube

warning of spyware adware etc.

Well i regularly visit video clip sites other than "nice and proper"youtube and i have never had a problem with spyware malware yet .And i have and use most of the best free anti malware anti rootkit programmes that there is.

Are these" prevention better than cure" programmes like site advisor a form of self imposed censorship

by turning the over cautious user away from visiting Sites that are not seen as being appropriate.Funny how mainstream youtube heavily regulated with the usual 1001 rules of use put in place is always as clean as a whistle and almost reccomended you should visit,afterall lots of people all active in one place is so much easier to monitor and censor

If you don't have probs with the sites that McAfee shows red on, fair enough, but it's not trying to censor anything, it merely shows results obtained from using the site in question. A red setting doesn't always mean spyware is present, if you click on the McAfee indicator to view site details it shows why they've rated it the way they have, could be spam e-mails if you enter your address.

To go back to the censorship thing, some really hardcore porn sites show green. So I'm told!!

Mcafee Site Advisor is worthwhile and you should not, uninstall it but, if you do you will get infected by adware or malware. If you wish to experiment by uninstalling it then why not do so and therefore prove to yourself that Site Advisor is worthwhile.
