There is not enough information to be able to accurately say, if you have or haven’t been infected.

Do you still have another anti-virus program installed as this could cause a conflict.

Have you installed the avast program or only tried the anti-virus cleaner, I suspect the latter. Download and install the avast 4 home edition, after installation it will rewuire you to reboot and a scan will be carried out before windows opens fully.

I suggest you visit and read the Users-FAQ on the Off Topic Forum. This will give you more of an understanding of what we need to help you.

You could search these forums for ‘Netsky’ without the quotes.

Or search Google http://www.google.com/search?ie=UTF-8&oe=UTF-8&q=Netsky-z there is tons of information out there.
