Unauthorized charges to my credit card

I Michael W Thompson, Oct 13, 2016 was charged $74.99 to my Discover Card by DRI' Kaspersky for a recurring that was not authorized by me. Furthermore I was charged $66.99 on Oct 18, 2015 that was not authorized on my Discover Card by me because of not being able to download DRI' Kaspersky anti- virus software to use. I suppose the recurring charge may have came from Oct 18, 2015. I request DRI' Kaspersky to return my funds to my Dicover Card in the said amounts of $74.99 & $66.99. I can be reached by e-mail at mwt12003@yahoo.com or by phone 925-209-4098. I await your prompt response.
Thank You
