Hello everyone hope you are well,1st time in this forum,have been useing avast a,v for about a year,was on win98se,but now trying winxp,(30 day trial) and when i installed AVAST (yes have the keycode)it offered & DID a bootupscan NEVER saw this on win98se,
Question :
Is there a way to have this done each time at bootup,(it allows me to skip/or stop if I wish) Thank you for the help & info & NOW have this forum saved also, “jazzy”
Win98 can’t run a boot scan, this is only available to NT based systems, such as XP, w2k.
The boot-time scan can only be scheduled one an as required basis. There are other scans going on shortly after running windows, check the scanned count: in the Standard Shield details, shortly after windows has completed its start-up.
Actually, we didn’t really anticipate someone wanting to run a (pretty time consuming) boot-time scan on each and every boot. On most machines, it takes 10+ minutes to complete (considerably more on machines with lots of stuff on their HDD’s)!
Hi & “THANK YOU” for the information,no problems as far as running AVAST,I just never saw the boot up scan befor on winxp, & thought it was a “hidden” option, as far as actual bootup scan 10 minutes?/(guess dialup or ?) it did my Compaq 7585,(650mhz,384 ram with DSL,) -yes I guess by computer standards its an old one had 5yrs and MY FIRST COMPUTER,and still seems to work good, but it did the bootupscan in about 30-45 seconds IF THAT LONG, thank U again & "Take Care ok,“jazzy”
Vlk,would be possible to QuickScan only system important files at boot time in the near future?
This could be scanned in like 10 seconds.
Something similar like AVG does in Win9x environment,but here you’d use current Boot-Time scan mechanism.
Define “important files” 
I’m afraid the time of file infectors is mostly gone now, most of the infections are caused by worms - and they can be any file on your disk, so I’m not sure if you could scan it in 10 seconds.
OK, I probably know how it could be done… but that would require rewriting most of the code contained currently in avast! Virus Cleaner for use in the boot-time scan module, which I’m afraid won’t happen (would take very long… it’s probably not worth it, sorry).
Maybe a quick’n’dirty (albeit possibly imperfect) algorithm for enumerating startup items would do…?
That’s what I meant - dirty it already is, and turning it into Native API would be a real pleasure 
On the other hand… creating a list beforehand (at the time of scheduling) wouldn’t be that hard, even though less “safe”.
