I am running windows 98 and having a lot of problems. (slow, frequent crashes, etc.) I have ran spybot, adware, and many other programs to correct problems, to no avail. I have been reading the forums posted here and tried to scan registry but it freezes up when it gets to:Repairing C:windows system.dat
checking system registry structure. I also ran a HJT. The results are:
