Have been suspicious Keeper download modules come from?

Today, I noticed an ad on a page, I visited. This announcement has been labeled 'Download Guardian' and showed a few pictures with products and prices in dollars. I wasn't expecting these ads on the site in question and so I looked more closely at it.
In addition, I find a lot of items contains classes starting with SF_ as SF_IIAD_EXPL and URLs starting with http://www.superfish.com. In addition, some javascript files are loaded from http://rvzr-a.akamaihd.net.
Then I looked at my modules and found 4 suspects:
Guardian dDoowload 1.6
Download KeeEper 1.6
Download keeper 1.6
DownnlOadd guardian 1.6
How could they have come here? I'm certainly not a not add them intentionally. Are they came with some installation software? Is it possible I can avoid these types of modules to install?

I should mention that in the programs and features of Windows 8 Control Panel that you can sort by date as a tool to study the programs installed together or very close in time.
