First of all Google uses algorithms that can't be rigged...they can be swayed by popular searches but it's not rigged internally. Secondly, Google is a private company so they can do whatever they want. If they were publicly-owned then they have a responsibility to be impartial but as a private company then can do/say whatever they want.

I have Kaspersky anti-virus link on my website and yesterday to check the links I clicked them. Today when I am on other websites I am getting google adsense/ads for Kaspersky.
People who click on Kaspersky from my website and they may buy later, they can click on google ads when they see them on other websites.

It's a common misconception that Google is a private company, so they can do whatever they want. Let's investigate that and see what the facts are. I'll just google the subject....
Anyone see a little problem there?
There is quite a bit on google about it.
You could use duckduckgo which is privacy oriented. There are also plenty of other search engines.
Or use a google account with your "nickname", no friends and no personal email.
I have a facebook, twitter, linkedin and google+ with no friends and maximum privacy settings. All of them are parasitic applications that track, sell your private data and block you from viewing content if you don't have them.
I also use a different computer for online activity than the one I use for work / exchanges & wallets and contemplating getting another for even more hardened security.
Privacy often is also not taken into account by Government departments and authorities. For instance when making a submission on a law change or certain complaints your name is publicly available. Then there are the databases that we don't have access to. Or private information about us stored by foreign governments.
