I am using Firefox 35.0.1 and I recently refreshed for the 3rd time to get my Plug-Ins to work. Still can't Adobe Flash Player to Work. So I took the advice of the-edmeister on page Flash Update Loop Although It Is UPDATED (with FF 35.0 never any problems!) [https://support.mozilla.org/en-US/questions/1044203] So I uninstalled Adobe Flash Player Read over the page, Used the Uninstaller as seen in first picture attached Next I checked the folders as directed to make sure they are fully Deleted. Yet You notice in the first picture Files are still left in the C:\Windows\SysWOW64\Macromed I have Win 8.1 and I found That there are other files than ones listed. How do I do a clean install of Flash Player? | Adobe Community [https://forums.adobe.com/thread/928315] these files will not Delete and created My issue. I have to load the Program *****Unlocker***I guess to allow me to delete them. They will Not delete also in Administration side of Windows. ""Warning"" do not use Unlocker it WILL NOT download in Firefox So I downloaded different Browser and scanned it using Virustotal Website and it has Malware why firefox blocked it for a reason! LockHunter is a free 64/32 bit tool to delete files blocked by any processes [http://lockhunter.com/] I scanned it using Virustotal and ok. I will be back in a bit after I do this all.
