and no icant download other anti-virus
Yeah so where were you expected to get those new anti virus from!!
Either you have deleted some important files in windows (while removing the virus) that were important for downloading things into the computer, in this case we could have got them back if your antivirus was working, but its not !
You will have to uninstall your current Norton products, and then reinstall a new one when the removal is complete.
You got more than one problem here!!
