how secure is web browser created in VB 2008

[razz]

The first program I created with VB 2008 was a web browser (as per instruction video). Ever since then I frequently use it. Excuse my ignorance regarding web browsers, but I wonder if I need to be concerned about security issues?
i.e. am I leaving myself vulnerable? Are cookies left behind and how would I get rid of those?

Thank you very much for your time.

The WebBrowser Control is basically Internet Explorer.

I'd have to agree with that, though I'm not sure exactly what and where the borders are. I know the internet cache and installed certificates is shared with IE, same probably goes for most if not all Internet Options as accessed from Windows Control Panel or IE Tools>Options.
