System slowing and freezing with Windows Live Messenger (MSN)

[vani]

My apologies if this is an ignorant inquiry, however, I appreciate any help that can be offered.

Since installing the security suite, whenever I sign into msn instant messenger my system seems to slow to a nearly nonfunctional state. When I sign out, things return to normal. Oddly enough, When I bring up the Windows Task Manager, I don't see the "100% CPU Usage" spike that would usually occur in such a situation. Yet I am unable to browse or open windows/make commands in a timely manner, such to the point that I feel I have to cease using the msn messenger program on this machine if this problem cannot be resolved. If it is of any consequence, I use Windows XP and Firefox to browse.

Thank you in advance. =)

Thanks for trying, Valen.

Disabling firewall had no effect; snoozing antivirus protection did, however.
(I had tried these both before posting, though only noticed when I tried again today, because it literally took a few minutes to take effect--I figured I was doing something wrong when neither seemed to do much.)

Still confused, disabling my anti-virus protection doesn't seem like a good long-term solution. Any further advice is much obliged.
