I googled for Trillian viruses and I came up with reports said only priated Trillian (Free or Pro) programs downloaded from p2p were infected with viruses.
I dont use p2p to dl the programs, just from official websites only.
Another security hole in any IM is users themselves. How? User accept a file from the friend (or so-called friend happens to be hacker) and open it... viola! Virus jump in and attack the computer. Best defend against is having IM use antivirus program to scanning any files.

Trillian could use antivirus program. Settings is in File Transfer, under the Trillian preferences by access the Files from Menu.
