ewido anti-malware seems to be a very good anti trojan software.
Unfortunately it is meant only for following OS: Windows 2000/XP/2003 Server, as such not for Win98SE.
Does anyone know a trick to install it under Win98SE?
Any suggestion other than Ad-Aware and Spybot? Those are also good and I use them, but ewido seems to catch more malware.

More and more programs are written to only work on a dirivitive of Windows NT.

You can do nothing about it....or to circumvent it. That's just the way it is.

Keep your AdAware SE/Personal and Spybot S&D up to date at lease several times a week and do a scan every time you get an update. This will help you a lot.
Don't forget to Immunize every time you get updates for Spybot.

Good Luck,

Frankly, do you catch malware guys ?

no, but i've downloaded a couple of trojans in my time.

Thank you all guys for the information.
I am highly impressed by the ewido.
It is pity that we cannot tweak it to run under Win98SE, I thought it might be possible with some sort of Kernel patch.

These are the free(ware) anti-spyware/anti-malware programs I know of:

Thanks to MDGx for your comprehensive information. There are so many options out there…
Based on your experience though, could you perhaps recommend which one is your preference for Win98SE that is possibly similar or close to ewido?
