how can I get my files back - restore is not working

Dear Sir:
I have EMC - Documentum install files that had a class removed by the antivirus software. I know the files no not have a virus. I highlight the files an select restore, but nothing happens. HOW can I get these class files restored to their correct jar files.

Thanks for your time

are you sure.... as a copy will remaine in chest when you restore

I decompiled the jar file and looked after I did the update. I will check again. Thanks for getting back to me. hope you have a great day.
