My free AVG does not work for my windows 98 Second Edition computer anymore. Can you suggest another free anti virus?
Grisoft stopped support for Windows 98 when they released AVG Free 8.0. As of the end of April 2009 Grisoft have stopped updating the older version 7.5 so there now is no free AVG product that protects Windows 98.
Avast! is the only free Windows 98 compatible virus checker we know of so you should download that, uninstall AVG then install Avast!
