1) I recommend to uninstall this:
Skype Click to Call (HKLM-x32\...\{873F8E7C-10E6-449F-BD7E-5FBA7C8E1C9B}) (Version: 8.5.0.9167 - Microsoft Corporation)
Unity Web Player (HKU\S-1-5-21-336042120-3881833094-1070839671-1001\...\UnityWebPlayer) (Version: 4.6.1f1 - Unity Technologies ApS)
2)
Download fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST/FRST64 and fixlist.txt are in the same location or the fix will not work.
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system.
Run FRST/FRST64 and press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run. When finished FRST will generate a log on the Desktop (Fixlog.txt). Please post it to your reply.
