Registry problem

Logfile of HijackThis v1.99.0 Scan saved at 3:36:17 PM, on 5/8/06 Platform: Windows 98 SE (Win9x 4.10.2222A) MSIE: Internet Explorer v6.00 (6.00.2800.1106) I had a problem of my computer crashing and when trying to reboot got a message that windows could not access the registry. After numerous attempts failing to reboot, I finally resorted to using an old boot disk I created a couple of years ago. The computer now operates, but it does some strange things. In addition, most programs that have been installed recently will not operate. When booting up the windows screen comes up and then I get the following message: "Cannot find a device or file that may be needed to run Windows or a Windows application. The Windows registry or SYSTEM.INI file refers to this device file, but the device no longer exists. If you deleted this file on purpose, try uninstalling the associated application using its uninstall or setup program. If you still want to use the application associated with this device file, try reinstalling that application to replace the missing file. C:\PROGRA~1\NORTON~2\NORTON~1\SAVRTPEL.VXD Press a key to continue." After pressing a key, the entire message above repeats and then shows: "SYMTDI.VXD Press a key to continue." After pressing a key, the entire message above repeats and then shows: "C:\PROGRA~1\NORTON~2\NORTON~1\SAVRT.VXD Press a key to continue." After going by these 3 messages, sometimes it will then boot up. Many times I get other error messages such as, "Explorer – This program has performed an illegal operation and will be shut down." I have gone to add/delete programs and tried to delete any Symantec or Norton programs that are shown, but instead of deleting it keeps asking for an install disk that I no longer can find. Any help you can provide will be greatly appreciated. Thank you.
