I want to install AVG 2011 in my Windows XP computer. I have tried it too many times but I failed to install. I am receiving error message as shown below:

Microsoft Exchange Installation Wizard

Setup failed while installing sub-component Exchange ActiveSync with error code 0xC0070643 (please consult the installation logs for a detailed description). you may cancel the installation or try the failed step again.

Please help me to resolve this issue.

My AVG 9.0 free version has an email scanner which scans my Microsoft Outlook. How do I change this setting? My current OS is Windows XP Pro with Service Pack 3. I am using AVG 9.0 and the Windows Firewall for security. Thanks in advance.

I just need an expert opinion about security warnings related to digital signature. For instance, I tried to install an application but a message popped up asking if I would want to run it even if the application’s digital signature has expired.

Please refer to the screen shot I uploaded. Should I hit Run or Cancel?

Warning – Security

The application's digital signature has an error. Do you

want to run the application?
