Avast free is about the best as far as updating many times daily and no need to schedule scans.

Some HELP in posting on Computing.net plus free progs and instructions Cheers

Sorry, I did not explain myself right.

I am looking for a reliable and freeware antivurs which can be updated daily in order to run this antivirus after booting with a bootable cd. Now I have the bootable CD. The problem comes up when searching for the updated freeware antivirus which can be run after booting with my Windows live XP Bartpe.

For example, it would be cool to be able to boot with bartpe CD and then plug a usb hard disk in which you can find not only a runnable freeware antivurus but the last updates for this freeware antivirus' virus definitions.
Do you know any freeware updated antivurs which would allow me to run it from an external usb hard disk after booting with a bart pe windows xp live?

Does ay one know one?

At the same time I would rather not having to burn a new CD every time I download a new update for the antivirus' virus definitions. That is why I would rather run the antivirus from an external usb hard disk in which the latest virus definition's updates are stored.

Well, actually it would be cool also if the freeware antivirus let me burn a bootable cd with the latest virus definitions in order to scan a computer in case a usb hard disk could not be plugged to the computer.

I guess Bitdefender rescue cd might be an option since it seems it lets download the latest software definitions after booting the bootable CD. Nonetheless, it would be cool if it could be run also from a usb external hard disk after booting with any bootable Cd.

Thanks

Ok, I found more or less what I was looking for:
F-secure. The problem is that it is not freeware.
Do you know any other freeware antivirus that provide the option to update virus definitions via another healthy computer with a USB stick like F-secure does?
Thanks

What's the problem with booting to Windows and running an AV scan. A lot simpler, no need to burn definitions to disk and achieves all that you need plus it will give you real-time protection which booting from a CD wont..

Well, sorry, I did not say that the computer is not able to boot by itself because it might have some boot sector damaged. Now I think you will understand why I would like to boot with my bootable CD and then run the updated freeware antivirus from a USB stick.

If you computer wont boot running an AV scan is unlikely to fix it. A virus scan will not fix a damaged boot sector. I would find out why it wont boot in the first place and fix that problem.

You should have explained what you are trying to do & why, right from the start. What you have in mind will not work.

Well, I just mentioned the example when the boot sector is damaged but it could be any problem related to an unbootable computer. There are times when virus come into the computer's hard disk and although windows boots, eventually you cannot do anything at all in windows, you cannot use your antivirus because of the virus. That is why it would be useful to be able to use an freeware antivirus application after booting with a bootable cd.

"That is why it would be useful to be able to use an freeware antivirus application after booting with a bootable cd"

That's what rescue CDs are for. You don't have to boot off a live CD such as BartPE, you just boot off the rescue CD & run the anti-virus scan.

You seem to be talking in generalities rather than saying exactly what's going on. Do you have a system that's infected or are you just planning for the possibility?

I installed Microsoft Essentials free Anti-Virus and I think its great ! simple to use updates quickly and does not interfer with the performance of my PC ! I had previously been using Norton Security Suite and I figured any free anti-virus would be a step down ,however I feel as if my computer has had a great load lifted off of its shoulders . The amount of running apps in task Manager is down by about 10 apps less ! If you look around for reviews you will find Microsoft Essentials gets mostly high marks for virus and mailware protection .

Thanks all for your help.
Jam,
I am doing some tests just in case. However, I do have a bartpe win xp live CD but the problem with this CD is that it does not get daily updates for its antivirus NOD32. That is why I would like to be able to run an antivirus without the need to burn it on a Cd and instead I would copy it to a USB stick everytime a new update is available to avoid wasting CDs with every daily update. Well, may be a rewritable CD might do the trick but I do not trust much in rewritable CD's. I would rather use a USB stick or USB external hard disk in order to run the antivirus straight away from this USB stick or hard disk without the need to install the antivirus in the computer's hard disk.
What do you think?

Thanks

You might try googling for portable anti virus....there are a few out there. Or you could get a free antivirus then make it portable, by removing the installer and placing it on your usb stick.

So search for "free anti virus" and then "make an app portable"
The programs to make apps portable are also free.

Why not just install Avast 5 (free) and schedule a boot time scan which runs before Windows loads?

Thanks wordlibrary.
Thanks Brim, but I was thinking as hypothesis that windows is unbootable with the internal hard disk where it was installed. So that would not aloow me wo schedule any boot time scan with avast unlessyou tell me how to do so.

Make a barts cd with plugins for av and antimalware. Boot to it to remove virus's.

I normally just reload the whole thing but it seems to upset people here. I know it works 100% of the time though.

If you need to do this on a regular basis then I'd recommend investing in Kaspersky - it has a rescue disk creator that uses BART in its 2009 incarnation or a Linux disk in 2010 (because BART cannot work with Vista or Win7). If the PC you are scanning has internet access then it will update before scanning (though the BART version was a bit problematic on this point), otherwise you need to recreate the disk before each use, either on CDRW or USB if the system can boot from it.

BART itself was a bit inflexible as far as running anything 'live', so I think you'd be struggling to find any AV that will update from within BART but if you post the query on BART's forum I'm sure someone will have an answer.

Thanks for the suggestion.
I tried by using Mojo Pac. I installed it under an external USB stick. The thing is that when I log in MojoPac, I see a simulated win xp which is not bad. However, when I go to "My computer", I do not see the laptop's internal hard disk. So I do not see how I could do what I wanted, that is to say: scanning the laptop's internal hard disk.
Am I missing anything?
Thanks
