I deleted it straight away. But does any one know about this virus yet.

Yes, I think so. I remember some talk about Adobe Acrobat and Adobe Reader vulnerabilities a few months ago. We all updated. It attacks when you visit a webpage that contains malicious PDF Files. Or if you open an e-mail message containing PDF file as an attachment. (Clean you disk) You might do a system restore to before attack...

Well I was scanning my computer for viruses and well I got this same thing, but when I try deleting it the thing says that it cannot delete and I dont know how to get rid of this bug. please help
