thanks for asking your problem on justanswer.com
which operating system is installed in your computer is it windowsXP/vista or some other else
please cancel my request. i found that this site was spyware from an advertising firm.i delete all cookies that i found with "mediaplex.com". I also turned off receiving cookies. i think this will solve the problem.
Actually even though all you found was a tracking cookie removing that wont stop the process or the spyware on your machine. It will only stop it from seeing where on the internet you are. It may also recreate that cookie. Please do the following to remove any left over remnants of it.
Please download and install malware bytes from here: Click here Once it is installed restart your computer and continuously tap F8 Choose safe mode from the menu and log into windows Then open malware bytes and run a full system scan Click on show results and then remove anything that it finds After that restart the computer normally
