Malware or Virus removel

I have a Windows 7 64 bit machine, it seems to be infected, when we try to down load anything, the file gets automatically deleted, I tried installing ESET, it stops at the end and fails. It seems that there is a software that doesn't not allow anything to download in the download drive.

Nrhode has a good post for you

Just before you do any other that uninstall Avast  and then restart the computer.

Not a good thing to have more than one anti virus program running on a computer.
Please note that the more advanced viruses cannot be detected while you're in Windows (virus hooks in first, makes itself invisible to all bigger names antivirus programs).
Therefore, the only way to really scan your computer is using a boot cd/usb. Eset NOD32 is a good one, but if you don't have a subscription, there are also free versions like the AVG boot cd ( Boot from CD, scan, delete viruses, reboot.
