I want Avast to do a boot-time scan in win98 is there a way to force it to do this?
when I have installed it on winXP systems it will ask to do it for me as part of the install.
Win98 doesn’t support boot-time scan, only NT based Operating Systems (such as XP) support this function, it is not a limitation of avast!
In Windows 98 you can boot with a CD and run avast! for DOS.
More info in ‘Links’ in my signature 8)
As David said, it’s not an avast! limitation.
