IE often runs slow and freezes, Windows Resource Protection found corrupt files but was unable to fix some

Hi, I notice often it seems IE runs slow on my laptop (fairly new HP laptop with windows 8.1)

Today I had to print a shipping label as I usually do, and after I paid for the shipping label I pressed download pdf, and it successfully downloaded the pdf label. However it did not open, it said "running security scan" and it froze on that for about 3 minutes.

I rebooted the computer and figured I would try again. I got the same results. Finally after 3 minutes the pdf file opened and I was able to print the label.

I did a google search for "security scan freezing" and came across a post which suggested running command prompt as admin, then typing sfc /scannow. I did that and after it finished scanning it gave me the following message:

"Windows Resource Protection found corrupt files but was unable to fix some
of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For
example C:\Windows\Logs\CBS\CBS.log. Note that logging is currently not
supported in offline servicing scenarios."

I opened the cbs.log but there is a lot of log notes written but I am not sure what they mean. Attached is a copy of the log,
CBS.log
 any suggestion on how to fix is appreciated.
