I just updated to the latest Yahoo! Messenger, and it was so slow as to be unusable (several seconds to respond to keyclicks). I checked Windows Task Manager and it showed mcshield using 25% of memory. I killed Yahoo IM and mcshield stopped using CPU. I uninstalled Yahoo IM and reinstalled it, and still have the same issue.
Windows 7 Professional, Mcafee Internet security. Yahoo IM 220.127.116.114-us

Can you please provide us with the below specifications

McAfee security center
McAfee Virus scan :
As a follow up, it does seem to be better today, with the slowdown only occurring after making opening a new conversation and clearing itself eventually. Perhaps today's update help. Yeesterday I had to kill IM to get rid of the mcshield cycles.
