Under Win98SE, my previous NAV setup included realtime bootfile/sector scanning – eg, if I renamed a partition, NAV halted the action and required confirmation. avast! 4 does not for my OS as noted.
Which makes me wonder if there are different precautions I need to take now, specifically due to the lack of live boot sector scanning? Does this make me more vulnerable to certain things, and if so, is there/are there specifics to watch out for?
There have been numerous posts about Avast's Boot-time
scans; I would encourage you to use this forum's "search"
feature to read about it.
Have you read the "FAQ's" ?
There is no lack on protection (on-access), just in scanning on boot time (on-demand) in my point of view. But it will be scanned into Windows later.
I think not. Anyway, only if you want, you’ll have to boot into DOS (each time) and run avast! for DOS… but it will be time consuming.
I really do not recommend boot time scanning if your system is clean.
