Using Zonealarm free version on my W98SE computer. I got the message from Zonealarm saying that an update was available. I down loaded it but when I went to install it, I get the message that it no longer was any good on W98. So I now have it downloaded, can't install it and can't delete the download. How do I get ridof the file that I can't use?

Operating System:Windows 98-SE (Second Edition)
Product Name:ZoneAlarm (Free)
Software Version:6.1
