ICQ tmp files outgoing connections?

I’m using ICQ client 10.0.12116 from icq.com and some time ago CIS firewall started detecting outgoing connections that weren’t there before.

Source files are always from C:\Users*user*\AppData\Local\Temp
File name is always icq****.tmp * = random letter or number
Outgoing connection to either or port 443

I’ve been blocking them, and it doesn’t seem to affect ICQ (unless it’s an auto update attempts).

Anybody else experienced this?
