Hello, I'm using vista with ie7 but currently I'm facing a problem.
There are web pages like Business Rumours which are opening by itself.
I've scanned my computer several times but no solution is found till now. Can Someone help me out! Please!!

It could be a BHO that installed itself while perhaps installing another program as an addon which triggers the page to open

Here is something to look into to see if you would be able to identify a BHO that you may not need or use

You can always uninstall if this does not help find out what may be causing pages to open

Try that, hope it helps out

Thank you man. I've downloaded that software. Now I can see lots of BHO and I don't see which one has to be deleted. Do you have any idea in what I can do next?

You can post a hijackthis log and can have a look there for anything suspicious

Do a scan only and post a screenshot here
