Ive done a little reading on these files, and was just wondering, should I be concerned about them, and what is the best SW to get rid of them?

Wasnt sure exactly what section to post in, this seemed like the best choice

index.dat is a file used by the Internet Explorer web browser. The index.dat file functions as an active database, which runs as long as a user is logged on in Windows. It functions as a repository of redundant information, such as web URLs, search queries and recently opened files. Its role is similar to that of an index file in the field of databases, where a technique called "indexing" stores the contents of a database in a different order to help speed up query responses.

What is Index.dat?

IE8 creates an "IETldCache" folder in Documents & Settings and %USERPROFILE% and containing index.dat. This behavior is related to new component in IE8 called Loosely-Coupled Internet Explorer (LCIE).

If you do a search on the net for How to remove Index.dat files, you will find many third party utilities which can be used. You can also follow these instructions while in safe mode.
