Affiliate Marketing Secrets

My sister does the virtual school online but we’ve been having problems with her going on Facebook and other stuff and not doing her work. We’re trying to find a program that will block all of that. I downloaded K9 web protection which did a really good job. I thought I could fix it where certain sites were only blocked certain times but I wasn’t able to do that (or I couldn’t figure out how). I heard Net Nanny was good but someone said it didn’t work well on Windows 7.
I really like K9 and will probably stick with it unless I find something with more features so please don’t bother suggesting anything unless it’s capable of blocking only certain sites at certain times like I said. The idea is allowing her access to her school work while blocking Facebook and other things but also completely eliminating a blocker during the weekends and such. The software we have now blocks constantly and can only allow constant access for an hour at a time. It’s a pain to continuously put in a password every hour just to use the computer.
I’ve tried several Chrome and Firefox add-on’s and some were fantastic but could be easily worked around by disabling them or just using another browser.
