Since virus corrupted the AV We would recommend to run SymHelp with Scan rootkits checked http://www.symantec.com/business/support/index?page=content&id=TECH215519 Next Run Norton Power Eraser https://security.symantec.com/nbrt/npe.aspx? Then Install our AV back on your machine and run a full scan with Upto date definitons If you still have the problem please create a case with support team

Hi Jdsouza,

Count of virus is huge in one system which has been corrupt the antivirus. How can i remove it?

Do you mean that the OS has been corrupted or the AV has been corrupted/damaged?

Is the threat still present on the computer?

If SEP is not functioning, then try the Power Eraser, as recommended above, or the SERT LiveCD tool.

For badly compromised computers, sometimes reformatting and rebuilding them offline is the best way to ensure that all traces of the threat have been eliminated.  Only add them back to the network when they are reinstalled, patched, etc.
