[SOLVED] windows security on VM
hi,
can someone tell me whether installed on a virtual machine (like virtualbox for example) Windows is prone to viruses as much as a normal Windows installation? Or is there no such threat for a Windows OS installed this way. If it isn't, what's the explanation for this?

Re: windows security on VM
It's just as possible to get malware as in a regular installation. It simply can't affect your linux host.

Re: windows security on VM
Absolutely true, BUT - installed as VM, you can easily backup your freshly installed "golden" Windows OS image and when things go bad (virus, etc.) restore that image.Zalbor wrote:It's just as possible to get malware as in a regular installation. It simply can't affect your linux host.
Many virtualization solutions offer snapshots that make it easy to backup or freeze a system image at any time. If disk space is an issue, you may compress these backup images.
Bottom line: It's faster and easier to restore a VM. And if your hardware crashes or you want to migrate to a new PC, you can quite easily take your VM to that new hardware (without the need for a new Windows installation).

thanks for the tip

Re: [SOLVED] windows security on VM
After researching active virus sites last year my conclusion is that you are virtually immune to modern malware when running in a virtual box. All the so called "Fully Undetectable" (FUD) trojans and viruses that I found out there detected that they are running in a virtual box and obligingly deleted themselves. The ones that didn't were not FUD and easily removed with Microsoft's Security essentials.monere wrote:hi,

However, be very wary of sharing files with the host machine because once you leave the virtual environment said viruses are less obliging

p.s. another thing to do is remove all forms of Java if you don't need it: Most infections got in via Java security deficiencies and drive-by.
Re: [SOLVED] windows security on VM
Well, I don't think I will ever remove java since it's needed by so many things. I will keep these tips in mind though.perduta wrote:After researching active virus sites last year my conclusion is that you are virtually immune to modern malware when running in a virtual box.

Re: [SOLVED] windows security on VM
you will surprised how useless java is really (unless you have a specific site that relies on it)monere wrote:I don't think I will ever remove java since it's needed by so many things.
java is not javascript
just do a small test: go to the plugins page of the browser you're using and disable java, now use your browser as usual for some time: did you miss it? did the lack of the java plugin broke your internet experience?
Re: [SOLVED] windows security on VM
uhm, I'm assuming you're talking about disabling java in Linux. Cause right now I am in Windows watching some online football and it needs Java to run (or is it flash player??)zerozero wrote:you will surprised how useless java is really (unless you have a specific site that relies on it)monere wrote:I don't think I will ever remove java since it's needed by so many things.

Well, never mind! I will do the test anyway, you just got me curious

Re: [SOLVED] windows security on VM
Oh, I was wrong then

Anyway, I looked at my plugins section of firefox add-ons and I have no java in there. I only have Shockwave Flash 11.5...., VLC Web Plugin 2.0.0, and Windows Presentation Foundation 3.5.30...
EDIT: forgot to mention that this is in Windows Vista, if it matters. I didn't look yet in Linux' FF
