Here is another free virus scanner you can try that works on Win98.

It's a shame it has been discontinued as it is a handy backup scanner. I checked
the link and it is still good.
The latest virus signature files are available on this page but I expect that they
will be discontinued this year as well.

You will need to download both zip files to be fully updated. If anything, this virus
scanner can be a little too sensive bringing up the occasional false positive.
