Spybot not fixing DSO Exploit

Please help. I have run spybot over and over, yet I still get DSO Exploit Errors. I installed dsosto2.exe and that (I guess) got rid of one of four errors. MY IE settings are secure, per https://www.wilderssecurity.com/showthread.php?t=27971. I have also researched this forum, but no luck. I just want to know if I have a potential problem here?

This is the spybot log:
