Ever since I installed Internet Explorer 8 I have found it very slow compared to the earlier 7 version.

In trying to find solutions to the problem some people say that the Spy
bot immunisation programme that lists thousands of restricted/bad sites causes slowing down because Internet Explorer 8 cannot handle the large listing.

I do not wish to disable this feature but does it slow down Internet Explorer?
Any advise about this or other solutions you have to the slow internet programme much appreciated.

Thanks in advance
