iPhone advertisement infected my Google Chrome

Few min ago while launching SKYPE I got a vibrating advertisement about how to win an iPhone, I've immediately closed that screen since understood it could be harmful to my laptop, and run Norton scan. While Norton 360 was working it displayed that it could not clean my Google Chrome browser since it is opened (while it was really close) and repeated this same display infinitely, something that forced me to cancel the task of cleaning the browser. I repeated this several times with same failure to clean the browser. What is the best way to overcome this problem. I run the quick scan and all problems were seemingly fixed according to Norton 360. However, each time I run SKYPE the same iPhone vibrating malware advertisement appears again. Should I uninstall SKYPE and re-install it or this will not solve the problem or this step would not solve this issue? I used my up-to-date Norton 360 antivirus software and it said there is no problem on my laptop, nonetheless this is already a problem. Thanks for any idea.
