I have worker.class, counter.class, verifierbug.class, arc.zip-53b4229a-4c856cf4, except the last one there are three Trojan.Byte viruses and the fourth one, I am not sure.

All these viruses are quarantined, but I do not see any virus in the quarantine, nor do I see if I scan the whole computer for virus.

But, I see them all in the virus history, how to delete them permenentaly, if I try right click and use permenently delete, it does nothing??.

If I try to move to quarantine, nothing happens, if I try clean, nothing happens.

But, I want to delete it permently from the virus history, do anyone knows how to do, a step by step procedure, your effort to help will be greatly appreciated. I tried to look for information in the microsoft website and Norton, but I don't think it is any simpler to follow up their steps.

thanks, Thegem
