Windows 7 Home Premium SP1 ran sfc /scannow. Message Windows Resource Protection found corrupt files but was unable to fix some of them...attached is the log.
I ran this because Norton 360 came across Trojan.zbot. The computer was then painfully slow and would hang. I did a system restore which seemed to resolve the issue. I've been running many scans with no sign of it or anything else. Considering doing ComboFix to be sure.
In regards to the sfc message - I ran a fix I came across a while ago - dism /online /cleanup-image /restorehealth - but I am getting error: 87. I've tried researching it to no avail. This has happened on a couple of other machines as well.
