Windows 7 Explorer crashes and restarts

[julio99]

Whenever I go to the "Programs and Features" module in Win 7 I get the trusty old, "Explorer has stopped working and is restarting" my taskbar goes for a split second and P&F closes. I have gone to Event viewer to look for a reason and 9 out of 10 crashes acording to the faulting module is "msi.dll" Isn't msi the Microsoft installer? Anyway, how can I go about fixing this or troubleshooting it? It is to say the least annoying.
My Computer is an Acer laptop Win 7 HP x64/8gb RAM /Core i5 430Mprocessor.

The first thing to do would be to do a thorough virus scan - with any security program you have plus perhaps Malwarebytes : Free anti-malware download

There may be a zillion of other causes, but this might be the first one of rescue.

Thanks for the reply Titanic. It would appear to be fixed. If there's a way to post this as solved, please let me know.
