I've just installed KIS and done a few scans and the scans are taking about three hours a go (at least double the time Avira takes). Looking at the detail - events tab, no files are coming up as being skipped because of iSwift. I've used the AOL version of KAV in the past and it worked OK then. The only self inflicted thing I can think I may have done is to run the following script to delete the object IDs: FOR /R %a IN (*.*) DO @ECHO. && @ECHO - %a && @FSUTIL ObjectID Delete "%a" Will this prevent the object IDs being created again? If so, what can I do to rectify. Restore an Acronis image from just before I ran the script. Or is it worse than that? Do I need to reinstall. Any thoughts and ideas most welcome?
