Internet Explorer 8 frequently prevents me from visiting certain websites that want to use some add-ons to display the content. The error message will be
Internet Explorer has closed this webpage to help protect your computer
A malfunctioning or malicious add-on has caused Internet Explorer to close this webpage.
What you can do:
Go to your home page
I have checked all the add-ons installed and I could not find any malicious addon listed there. Did a simple search on Google, the solution is quite simple. It seems Microsoft decided to add some extra security to Internet Explorer 8 by guessing which websites are insecure. 
Open Internet Explorer 8 –> Tools –> Internet Options –> Advanced.
Uncheck the option ‘Enable Memory Protection to help mitigate online attacks’. This can be found under Security section.

Security feature workarounds are always useful.
In this case this particular thing was preventing me from using OnlineSBI.

Thanks so much for a quick fix. It was preventing me from using iLink for a webcast.
