Hi forum,

I have brand B anti-virus software (AV) in my Win 7 professional OS.
I also installed xp mode and have a brand A AV in it.

One day, I was browsing with ie and brand B AV blocked a link which was harmful. Then, I curious and copied this link to xp mode’s ie and see what would react about the brand A AV. What a surprise! The brand B AV from Win 7 pro junped over to the xp mode and blocked that link. No response from brand A AV instead.

Is it normal ? Are 2 OS completely separated ? If so, should I need to install AV in the xp mode ?

Please advice and thanks.

Yes this is quite normal, as your XP mode runs in a Virtual Machine.
All out- & inbound traffic/data goes through Win7 first, so that AV would be the first to detect trouble. :thumbup2:

As the XP-mode AV does not scan outside the VM, it can't hurt or conflict with your main AV solution, I would let it be.
Especially when regularly using password-protected, encrypted and/or compressed files and such...

Thanks.

It is hard to find the detail infomation about the xp mode. I am glad to have your advice.

So, in my case, I have no way to check how powerful of the brand A AV does unless I have to install it in a real OS, right ?

You're very welcome! :)

To answer your "strength" test-question:
Well.., no.., but in fact, some people make a living off testing such things for you. Also, I sincerely hope you are not receiving too much malware samples to test that thoroughly in the first place :P
In short, there is no "best" AV, especially for end-users, only 'sufficient' and 'totally useless'. (lol, sorry)

To aid you in your quest for the most fitting AV solution for your needs:
http://www.av-comparatives.org/ is widely known for it's clear and easy to interpret tests.
Also, you could spend some time on VirusTotal.com to see with your own eyes what scanner A finds compared to scanner B.


It's very wise of you to have a second opinion available though! (Although the one in VM = XP mode, cannot be relied upon to scan your Win7!)
Active AV can be successfully operated alongside on-demand Anti-Malware solutions like MBAM for example, and will not conflict as long as you keep the active protection module from MBAM disabled.

I personally also like to use LiveCD's once in a while, but I'm paranoid, I have to admit. See Kaspersky Rescue CD and F-Secure Rescue CD on Google for more info on those ways of scanning, they're free (well, apart from a CD-R) as well.


Happy 'puting!
