You have to exclude the process and i believe that you are using file and folder exclusion. Please use the below KB article for process exclusion.
Best way disable the mcafee agent services and then get the exclusion created for CIPCLOCALEDOWNLOADER.EXE in High and low risk where you have to disable on read and write in low process policy.
the other way around to use procmon to see the Mcshiled is scanning the cisco ip communication files or not.
thanks for response, but I excluded it as I said before there is no log to blocked it. but clients systems get slow when use cisco ip communicator.
