Thank you for your fast response! I just looks under
MyComputer\HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Security, there are two options : P3Global and P3sites. no suspect were found, P3global -> default (value not set), enable (0x00000000(0). P3sites -> v(value not set). Any suggestion?
My IE can not download antspyware from internet, like I said in previous message. Norton anti-virus 2003 didn't find any virus. What do you think? Thank again.
