If I'm understanding, you have trouble with Windows 98 and avast because you have McAffee antivirus installed in this computer?
Please, uninstall McAffe, clean your Registry (search the board for Registry Cleaners suggestions or you can find many free versions of these registry cleaners here:
http://www.snapfiles.com/Freeware/system/fwregtools.htmlTo remove McAfee you need to do via Add/Remove and then the manual removal of the registry keys left behind with their on-line instructions.
They've released VSCleanupTool (
http://download.mcafee.com/products/licensed/cust_support_patches/VSCleanupTool.exe) to do that either, just go to
http://www.us.mcafee.com and click the Tech Support tab (provide your version number in Step 1 and select install/uninstall in Step 2). You can go to their user forum at
http://www.forums.mcafeehelp.com if you should have problems or questions. Check
