every website that has ever been accessed, take screenshots of web pages, block web pages according to content and even send you messages via e-mail once conspicuous(可疑的) activities have been reported and logged. Just think, you or your children could be browsing and searching through the Internet and inappropriate content pops up with several different windows. You try to click out of the windows but you accidentally click one which releases spy soft-ware, infecting your computer. Guardian Eye blocks unwanted content from popping up or appearing to the users, which I thought was extremely convenient. In this way there is not even the slightest temptation.
This product helps prevent damage from being done to your computer and worse, your identity. It's quite the product and it offers a small version so you may try it out first. If you'd like the full package, it's a one-time fee of $39.99 and can be installed on unlimited computers for your convenience. It's a nice deal and I'm considering getting it again considering I do a lot of writing on various websites myself.
