Hi, quick question I have vista ultimate 64 bit and on the other partition I was going to put vista ultimate 32 bit on there so that way I could run the avast boot scan which I know will work for the 32 bit partition, but will it also scan the “64 bit” partition as well or just forget it? I mean 2 partitions is still part of the whole PC but wasn’t sure about that. Thanks!
avast boot time scanning is performed in all Windows partitions, so, yes the scanning will caught the 64bits installation.
Hi tech,
Just out of curiosity, is the same tru for a dual system like Windows and Linux?
I mean, if I schedual the boot scan in say Linux, will it scan the windows partition as well?
Cheers.
If the partition is mounted, i.e., if Linux could see Windows and viceversa (there are system files mounters for Windows to see Linux) yes, both system will be scanned.
As far I know, at boot time, neither Windows nor Linux would be able to see the other partition.
Also, Linux version does not have a boot time scanning 
Thanks tech,
I was wondering if there really was a boot scaning option in Linux. Reason was that I keep thinking of switching to linux (Ubuntu) and since I know that avast is available on this system as well I am glad I can still use what has been thus far a reliable product. However I have been reluctant to do the dual system because of this incertitude that I can have equal security messures on both OS, so that one will not compromise the other.
No, there’s certainly no boot-time scan option in Linux.
You don’t need a boot time scan on Linux. In fact, you don’t really need an AV at all, except to scan for Windows viruses.
In Linux, you need to think about security best practice- follow that and you’ll be as secure withoout an AV as you are with in Windows- if not more.
Man, using dual boot and Linux does not depend on the antivirus running on Linux for sure.
I think you won’t decrease protection. I have dual boot Vista/Kubuntu in my notebook
Thank you Tech and FreewheelinFrank,
that puts my mind at ease. Now I only need to get pass this peky loader problem but, that is for another forum.
Thank you for the info. I can now partition vista 32 bit over my windows 7 64 bit and do a boot scan. I personally think windows 7 is almost exsactly like vista more like a service pack 2 but I can’t stand the whole taskbar I hate it, I know everyone else loves it but the “show desktop” being all the way over on the right sucks. Anyways now I will now for sure if I have a virus in my 64 bit vista once and for all. ;D
Btw, the idea of the boot-time scan is to run the scan early in the boot, before the usual Windows malware has a chance to activate (and possibly interfere with its scanning/removal).
However, in a dual-boot system, it doesn’t make much sense to scan the other operating system from a boot-time scan… it’s better to fully boot into one of the operating systems and scan the other one using the usual Windows scanner (which has more options, more unpackers, … than the boot-time scanner).
But what about those viruses or malware that are hidden in the startup in 64 bit that avast can’t find cause it doesn’t support 64 bit boot scan?
Oops, sorry, I’ve forgotten that Igor.
First of all, avast! is able to find many viruses even if they are running
But what I was trying to say is that if you have a dual boot system (32bit & 64bit), and you want to scan the 64bit system thoroughly, it’s better to boot into the 32bit system, start the ordinary scanner there (e.g. the Simple User Interface), and let it scan the 64bit partition (or all the disks) - than to use the 32bit boot-time scanner to scan the 64bit partition.
Got ya. Thanks!
