The thing with malwarebytes free is that is doesn't offer real time protection. I would also like to add you should run a antivirus program with real time protection, this will help with things like usb drives dropping payloads, websites running malicious scripts, etc. Then lastly run something like a adware cleaner http /or http /better yet use both. Next delete all history, cookies, data etc. First download and install the app web of trust to chrome or WOT it will block any websites that people have reported, 2nd disable java script, and then slowly build your trusts back allowing them to run JavaScript on your page again from websites that you normally go to.
