Iphone

Hope someone can help and resolve my misery. I opened an e-mail (disguised as a returned undelivered mail) that announced that I had sent out the I-Worm.Netsky.q virus. It contained an attachment that I did not open. I checked thoroughly both my directories and registry, as well as running two virus checker programs (I run AntiVir ver. 6 as resident), but found no trace of infection. Since re-booting my computer two hours after the incident I have found many things failing, for example:

Messages received after login: 41c: qttask.exe -No Disk. There is no disk in the drive. Please insert disk into drive \Device\Harddisk2\DR7

Messages in Event Log:

Event 17: \Device\avgntdd: Started filtering!.

Please help as I cannot determine what is going wrong.
