Hello! I am running Windows XP Pro operating system with Service Pack 2 installed and Internet Explorer 6. From few days ago when I start this browser I am asked by pop-up window to confirm downloading of some strange Security Certificate which is not connected with Windows XP. Can you tell me what is this?
Hello! I think that your computer is infected with some malicious software (probably some spyware). But, for any case, perform deep scan of your system from Safe Mode first with antivirus program, then with antispyware program. I am sure that you will find some nasty and that you will remove it.
