Question Symbol Characters

Hi,

I'm not sure how to describe this. But, I was trying to install McAfee Firewall 3.0 on my PC that runs Windows 98. The installation menu pops up and only half of it is readable. That half is all in English. The other half is random characters (squares, circles, diamonds and some others I
can't explain). I tried to use McAfee's help but it took 1 hour to connect to somebody who didn't help at all. I then tried the CD on my brother's CD (his PC is WIN98 too) and the installation menu came right up and it was perfectly readable. So,
I now believe the problem is on my PC and not the CD.

Any suggestions as to what may be causing these characters to appear instead of text?

Thanks,
Shawn

Funny characters: 
The above are Wordpads interpretation of a repeated Control Code character. Everything is subject to interpretation! The funny characters you see probably are being interpreted as Control Code Characters. Why? Any of a number of reasons: missing or damaged font file, registry / INI error - causing wrong application and/or viewer or dll function to be called, and on and on.

In the "old days" Control Code characters were used to format text. The easiest way to show you that things really are subject to interpretation is a demonstration. The batch file below will show you up to three differing views of some of the DOS Control Code characters. No doubt, some will be familiar.

The batch builds and then invokes a debug script. It is not to be edited by you, or by anyone else with limited DOS knowledge. It has been written especially for Windows 9x versions. The version of Windows is not tested, however, you have control through a series of choices and one key press responses. The suggested name to save as is "NN.BAT". Suggested use: DOS Command Line entry.

Usually copying batch files or scripts off the Internet and executing them is a very bad idea. Decide for yourself wether or not to do so now.
