Hi
I am looking to move back to Avast and want to find out if the new ver 5 has X64 bit version for Windows 7.
I searched around but was not able to find any info on it.
Thanks

Hi,
there’s only one version, and according to your OS, will install as 64 or 32 bit. This said, even when installed as 64 bit (so in the program files folder as opposed to the x86 one), main V5 processes as seen in task manager appear as 32 bit. Read sometime ago that a few things were actual 64 bit components, but can’t remember what exactly…I guess a look at process explorer (sysinternals) could tell more.
edit: don’t know what I was thinking of, the driver is 64 bit.
When I installed Avast Free version 5 on my system (Win 7 64bit) it installed directly to Program Files folder (not to Program Files x86) so I guess it 64 bit version recognized automatically.
in theory yes, but the program files folder is…just a folder 
ps: the driver is 64 bit
Fully agree with you, It was only a clue that it goes directly to native 64bit folders…
A look at cnet site gives some details:
Operating system: Windows 2000/XP/Vista 32-bit/64-bit/7 32-bit/64-bit

OK. I just installed the AV and even though it installed to the correct “program files” folder, the main process like Avast UI & Avast Service are still 32 bit. I am a bit disappointed with this, specially now that loads are new softwares are 64 bit.
My first impression of the software is good but because i have a x64 bit system, i am making a point of only installing 64bit version of software and because of this, i dont think i will hold on to Avast for too long.
Okey, but the software runs just fine on 64bit so no reason to be disappointed
But it is your choice! Good look outside Avast-land 
@Bluesman…
I think you got me wrong. I am not saying that Avast is a bad product. Infact it is a very good product and the reason i used the word “disappointed” is because i expect more from a quality product like Avast. With the release of version 5, I expected Avast to provide a true x64 bit version.
Unfortunately, antivirus software is not a typical product which would greatly profit from x64 architecture. The harddrive is always the biggest bottleneck for antivirus.
but still, it works good on 64-bit systems and protection level is good enough for home users…
I would also like a pure 64bit version of avast! for my 64bit copy of Windows 7.
MSE has three versions, XP 32, Vista/7 32 & Vista/7 64. 8)
and what would that change ?
I was just responding to sdevil’s posts.
avast! 5 is better than MSE x64.
and you mind answering my question somehow…
and you mind answering my question somehow...
I thought I did…
not really no ;D but nevermind :
64 bit operating systems emulate 32 bit to allow 32 bit applications to work. Because of this fact there is more overhead using 32 bit applications in a 64 bit operating system. Microsoft did a great job emulating 32 bit in Vista and 7 so the hit is usually very small. The only reason software companies do not make native 64 bit applications is cost.
I was going to post that pk answered Logos’s question, but there’s no need now.
There’s no “emulation” here (unless we’re talking about Itanium, not x64).
Basically, the CPU is just switched into 32bit mode (when executing the 32bit code). The overhead is so small that it’s kinda pointless to talk about it.
