Links within my emails

I dumped Norton last week and downloaded McAfee that was free with Comcast. Ever since I can not open "link" within my emails. I have tried everything including a useless internet consult with McAfee. I had this problems a few years back but can not remember how I corrected it. I can't do a copy and past as the address is not on some of the links. I get some things from my granddaughters school with links that just say "click here" and when I click it it does not take me to the internet which is where I know it will take me or else it will be a pdf file attached. HELP!

This happens in all links, even ones I send myself from the internet. I am using Windows XP and Internet Explorer and Outlook Express.

Thanks

Go figure this one, I was able to register the one you said would not register:
regsvr32 msjava.dll

However the following one will not:
regsvr32 mshtml.dll. It says "was loaded but the dll Register Server entry point was not found. This file and not be registered.

I followed the steps specifically at Microsofts site that you liked me to. I even restarted my computer and still links do not work. I think I need to change my computer knowledge to "don't know very much" ! LOL

Any other suggestions? Thanks so much!
