Here at home almost cease to be able to use the computers to access the Internet, because after 5 minutes of having Firefox open Firefox is slow and did not let him do anything.
This started after the last update to the SiteAdvisor Live.
I hope this error is corrected as soon as possible.
Does it happen when using Internet explorer?
Try removing Siteadvisor via programs and features and when asked remove only Siteadvisor. Reboot and try the net and see it issue still occurs. It it does or even if it does not reinstall siteadvisor from the Mcafee site.
If still happening best to call support as they will assist you.
I've uninstalled McAfee Total Protection 2014, and returned to install and the same thing happens.
I used the MCPR tool - 6.8.709.0 and Mcpreinstall - 22.214.171.124.
This problem only started happening after the last update to McAfee SiteAdvisor Live, which was prior to version 126.96.36.199 and Firefox has always worked well, after upgrading to version 188.8.131.52 started this problem and Firefox get slow process Firefox cpu above 50% reaching 100% usage.
Welcome to the Community. As with anything, it is entirely each individual,s preference to which Browser in which one chooses to use. I have used both Chrome and Firefox in the past. However , after having to remove infections obtained through both Firefox and Chrome from my Daughter,s machine.
And to include their frequent Version updating of their Browsers respectively. Which as you can see does create issues with popular Extensions-Add ons. I have chosen to use Internet Explorer 11, for It renders pages just as fast,if not faster than the others. And I never have the reoccurring issues it seems, as Chrome-Firefox users do.
Plus I have never once been compromised by doing so. ( That doesn,t mean it couldn,t happen )
By showing your Screen Capture above... Are you experiencing the same issues in IE8 with Site Advisor,as you are in FireFox- Chrome? Just wondering?
