Hi, I know it's time to update, but I am still running my Win98se laptop and it has been acting oddly for about a week now. First here's what's installed: Resident: Avast Free, Winpatrol, Kerio FW. FF 2, Macaffe site advisor. on demand: SAS - did have A-squared too but new version does not support 98 anymore - any suggestions for a second line scanner would be appreciated. Spywareblaster, Symptoms: When I boot up all seems fine - but sometimes I cannot open an application - Explorer freezes with [not responding] in taskbar. Sometimes Msgsr32 also freezes. At other times applications like FF load but very slowly. Actions do seem to have slowed down lately. At other times Explorer reports an illegal operation and shutting down is the only option. I was able to boot into safe mode - so performed Start 'regsvr32 urlmon.dll Enter reoprted urlmon succeeded, but rebooting into normal after seemed to cause the same error. I also perfomed a full virus scan in safe mode and Avast found nothing. I also ran Stinger. I checked for hardware conflicts using Start-run- hwinfo /ul tool. Nothing odd. As symptom seemed to occur particularly when I tried to open SAS, I went into msconfig and turned it off in startup menu. Things seem to have improved, but I cannot open SAS anymore. (although Explorer has frozen since). I have noticed that it's taking longer for applications to open. Nevertheless at boot up all apps load and Avast updates automatically as usual. I also used Fix-it utilities to rollback settings to time before the problem, but Explorer still freezes when I try to open SAS. Could it be a corruption of the SAS programme? I don't think I was informed of the new update. So should I download a fresh copy uninstall/ reinstall SAS? Should I use the resident uninstaller or Windows add/remove? As windows appears to work without SAS loaded, and applications seem to take a while to load, I have considered a virus/malware despite being careful, but Avast and Stinger have found nothing (Cureit on line free scanner is running) I will also install Hijack this and report back if reinstalling SAS has no effect. Can anyone suggest any other malware scanner that will work with Windows 98? Finally, wonder whether it's a symptom of a dying HD Any suggestions gratefully received.
