My daughter picked up this trojan via a link on msn, bless her, we have 2 of the same, picked up on seperate occasions. I gather it’s also known as gaelium. It will not stay in the chest and pops up every time the computor is switched on, it also prevents closing down. It takes over msn and sends messages out of our control so we have uninstalled msn for the moment. I’m not a computor expert and if this trojan has been around a while it’s just arrived here in France and is causing problems. The french forums say that it’s impossible to get rid of but I can’t believe that. How did it get past avast? Please help us get rid it.
