safari problems

Thanks for your quick response, reboot it. When I went to safari extensions I found something called "Mix Builder" which a quick search revealed was some kind of adware or malware. I deleted it. So far, safari has been ok, but it's only been less than an hour since I deleted Mix Builder so I'm not sure what will happen over time. I'm betting that was the problem only because no other extensions were shown and there were no unknown apps in my applications folder. Thanks again for your help.

Thanks for your quick response, Eric Root. I believe the suggestion made by reboot it will work so I may not have to download any other program to solve my problem. Nevertheless, I am saving both responses just in case. Once again, thanks for your help.

Hi.  I just wanted to update you on my problems with Safari.  The solution you proposed and I tried did not work for long.  So I proceeded to download Malware Bytes as Eric Root suggested and you suggested as a second possibility.  Unfortunately, Malware Bytes disabled the antivirus app I already had on my mac.  I did not realize the app I had detected adware.  Long story short, I had to contact tech support to get things fixed.  They told me that adding an antivirus app can result in disabling any antivirus app already have.  I wanted you to know this can happen so that in the future you can decide whether to add to your advice that having more than one antivirus app may cause a problem.
