What is the name of the trojan shown at the time of detection? Have you noted any suspicious behavior on your system ? If so, what ?
Thanks for responding. Rather unhelpfully the security report doesn't name it, it just says it's found one. I haven't noticed anything unusual other than applications running slowly and browser pages crashing. I think the latter may be more due to slow exchange connection while we wait to upgradeto fibre. Sorry not to give you anything much to go on!
All the best
Could you check the Anti-Virus scan logs, it must have a name for detection occured.
