I have an puzzle and I'm out of ideas. The internet turns up no clues, so I am looking for assistance.
The problem may not seem huge, but it affected multiple PCs, multiple users, different Windows OS, different versions of Outlook and on the same company network.



The problem;
Intermittantly, partial text sent via email is randomly enlarged to 100 .
This is after I hit the sent button

• It does not affect every email
• It does not affect every word
• It can affect a series of words.
• We have 3 computers connected via LAN, 1 is currently affected, another was affected [No longer has the security software, also was formatted]

Potential suspects;

Trojan - We were informed our website was broadcasting Java script

IT Telecoms Provider - Their state is not on their side

Security Software - CA Security was a prime suspect, as issue only appeared when this was installed [Disabling CA-Outlook Add-on did not work]

User/Other issues - A problem I've not thought of?



Solution;
Unknown



Please, any ideas or assistance would seriously make my day.
I wish to solve this, and also provide the internet with an answer!
