I was downloading a program from limewire and unfortunately it had an application extension to it that I did not want. I got rid of the program however the dll remained. I tried to manually delete it, but the error keeps coming up as destination folder access denied. When I try to continue through window, it says that I need permission to perform the action.

The information for the file is:
vbzip10.dll
file description: Info-ZIP's Zip dll
Company: Info-Zip
File Version: 1.1.0.0
Date created: 12/14/07
Size: 144 KB

Also I have a worm that is hiding on my computer. It's under users and the folder is "-". It also appears under setup.exe yet when I try to delete all the zips in the setup.exe file, my computer says that the file is not responding and it will not allow me to delete. I was able to find it on winrar and it has 49936 zip files in the setup.exe file. I deleted winrar yet the zip still remains.

I tried to run my mcafee virus scan and it has been running for over 8 hours and has quarantined over 2907 files so far which are all zip files. Could you please help me get rid of the file. Thank you.

This is the infection you have:

It's a P2P worm with 'Bot' characteristics. You'll need help cleaning from your machine.
