Edit: Typo on the title, trojans* Sorry about that, but I can't seem to fix it. Hi there.. I'm new to this site but it seemed like the one who could offer me a solution. Eset Nod32 keeps quarantining these viruses called Sirefef.AE, Agent.BA, and just now it asked me whether or not I want to quarantine some threat called Sirefef.EZ! I'm sort of a newbie when it comes to these things so I have no idea what to do... I'm afraid they might harm the computer and the antivirus doesn't seem to be doing its job in protecting it.. What do I do?
