Virtual machine questions

post #1 of 12
Thread Starter 
I see people on youtube testing anti-virus on virtual machine, so i was wondering If i install say windows xp in vm, deactivating the modem connection in the vm so that it doesn't have access to the web, once xp installed i do a restore point then installing a program or a game that i'm not sure if it's safe, if it contain malware or virus, could my main machine be infected since the os in the vm is itself a big file on my main computer?

Nope use vm all the time no its embeeded into the vb hard-drive and it only see's the hdd (virtual one) so it cant go past that into the real computer its 100% safe thats the idea behind it so that people cant test without having to worry about their real machine.

In theory, yes, if there's a security vulnerability in the VM host (i.e. VMWare). But in practice, not really.

Alright and for the system snapshots since it's the vm that take it not windows, can it be corrupt by malwares or viruses?

The snapshot is stored on your hdd but thats it. Even if you had malware/virus on it there is no way it can escape from that file. Even if you decide to run that snapshot again. It`s a close system.
Besides if you know the snapshot is infected delete it.
You would after the instalation of the OS make one that is 100%cean and return to this anytime you think something went wrong. Doesn`t have to be a virus e.g you messed up the registry

Oh was and am confused.
You should go WITH the VM in the internet. Download and visit websites that you are afraid of. This is the protection. If you download something to your real OS and put it in the VM
and then try it there... Then it was on your real hdd which is not what you want!!!
Disclaimer: You shouldn`t download ANYTHING that is not legal! Most stuff downloaded legal won`t contain viruses or malware (in most cases).

Let's say a friend got games that want to give me, but i dont know if it contain virus or malware so i want to tf it to the os using an external hdd, the problem is when i plug it, it is also detected in my main os, so would it be dangerous? And for my other question, is it possible to instal the OS file that i need on a external hdd, when i would turn it on it would detect in the virtual machine software ready to run the os..

If you want to go about it the legal way:

1) Use a sandbox program (but most of them are complicated to use, so look below)
2) Download and use avast! as your antivirus and from version 6+ it has a built in sandbox for .exe files that aren't trusted. https://support.avast.com/index.php?...eid=455#idt_09

Free and easy to use.
