Is virtualbox a virus?

Question

I know a lot of people have asked this before, but I just wanted to clarify, because when I was in my virtual desktop, and I went on a site and my antivirus on my host machine went off saying that they blocked a threat. This scares me, because I want to use a virtual desktop to make youtube videos showcasing viruses. Is it just a false alarm? Is there a way to make the viruses not transfer to my actual computer?

My OS on the virtualmachine is windows XP 64bit and on my host machine its windows 10 64bit. My antivirus is avast. The infection says: URL:MAL 185.38.187.84/Chmj.htm

What was the threat, can you give us more information in regards to the warning, what site it was , what antivirus are you using etc. — MrDeanosupreamo, Feb 21 '16 at 01:49
What is the OS you are running on your VirtualBox guest machine and what is the OS of your host machine? Without more details, I think this question is unanswerable. In general perhaps the antivirus software is detecting network traffic from the guest OS on the host OS and all of the sudden pulls a [“Chicken Little”](https://en.wikipedia.org/wiki/Henny_Penny) and flips out. In fact I am willing to bet the network issue is the issue. — Giacomo1968, Feb 21 '16 at 01:51
Don't write such low quality posts with crazy questions. At least to make things better you should add a screenshot — Suici Doga, Feb 22 '16 at 02:01

Your antivirus blocks any network traffic which is malicous on your PC. Kaspersky detected ECAIR antivirus test file inside a VirtualBox Windows 10 VM and blocked it when I went to the ECAIR website

So it's a false alarm? – Andrew Feb 21 '16 at 02:02
No it is a virus which could infect your host.So I recommend that you use VirtualBox in Linux or Linux Live USB / CD – Suici Doga Feb 21 '16 at 02:05
What? You telling me VirtualBox is this unsafe? Damn! – Cestarian Feb 21 '16 at 02:09
Is there any way I could possibly make the virtual machine not able to communicate with my host, so it can't infect my host? – Andrew Feb 21 '16 at 02:10
Install Ubuntu(which doesn't need antivirus and doesn't get viruses) and install VirtualBox there – Suici Doga Feb 21 '16 at 02:13
The EICAR antivirus test file is not a virus. It's an intentional false positive to confirm that antivirus is working. – David Schwartz Feb 21 '16 at 02:29
Yes I know that – Suici Doga Feb 21 '16 at 02:34

Of course Ubuntu can get viruses - who told you otherwise? – Jonno Feb 21 '16 at 04:18
Ubuntu viruses are quite rare – Suici Doga Feb 21 '16 at 05:09

@Cestarian It is not a virus.The guest has a virus – Suici Doga Feb 21 '16 at 05:37
@SuiciDoga yeah but what I meant was, it shouldn't be that easy for viruses to infect the host from the guest... – Cestarian Feb 22 '16 at 00:24
