Start>Run>Regedit
From the below locations in Regedit chage your default home page to google.com or other.
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\Main
HKEY_ LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Main
HKEY_USERS\Default\Software\Microsoft\Internet Explorer\Main
Just replace the attacker site with google.com or set it to blank page.
» Now we need to kill the process from back end. Press Ctrl + Alt + Del
Kill the process svhost.exe.( may be more than one process is running.. check properly)
» Delete svhost32.exe , svhost.exe files from Windows/ & temp/ directories. Or just search for svhost in your comp.. delete those files.
» Go to regedit search for svhost and delete all the results you get.
» Restart the computer. That’s it now you are virus free.
