If it is really a worm or trojan, I can suggest my favourite, www.pandasoftware.com I have bought norton antivirus but I hated it and also it never stopped anything from entering my computer. Now I see the alerts that entry is blocked cause someone or something tried to enter... I like that! [Linked Image] There is a free 90 days version you can download. Also here it is cheaper than norton, about the third of the price.

The world is full of beauty if the heart is full of love
