How to tell if virus is auto-downloaded/installed?

[Crazyasian123456]

Long story short, an embedded video for a movie linked to another site with a JavaScript popup "contact tech support" scam along with a "BSOD" screen. Is there a way to tell if a virus downloaded and executed itself in the background during the popup? (Killed chrome with taskmanager and nothing showed up in control panel in terms of pup). Malwarebytes and Bitdefender didn't detect anything so I'm assuming nothing happened other than the popup.

I did take a screenshot of the site itself, has anyone seen these guys before? climbingupnow(dot)com/pop

Run a quick trial of Hitman Pro.

Also run ADW Cleaner , if you are clean on both of these you should be fine.

No virus, yes I have seen before, many times!
Make sure your homepage is as it was and you have no suspicious extensions or downloads (CTRL+J), otherwise you're clear.

I HATE these fake virus pop-ups. The sad thing is some people fall for them and end up paying up.

I'd suggest installing Ublock Origin to prevent this from occuring in the future. Whitelist the sites like here that you know are safe though so they can still gain ad revenue!

Thanks you two for the help, even though original answer is slightly unanswered (how to tell if a virus is downloaded/installed in the background). That said only things that came up was a google analytics package from Auslogics (dunno how that got on there) and an old soluto file path that stuck around after I uninstalled it (when I ran hitman). adwcleaner didn't detect anything other than a bunch of old registry files.

You should be fine , usually as long as you don't click on the ads you are fine.

Oh it wasn't an ad, it was some site running a Java popup, but thanks though.

Your welcome.

Yeah, a normal HTML / JS / Flash pop-up cannot touch your local system, it could download a file but not install it.
I doubt it was Java actually - I have not seen a pop-up that uses it, and you would have had to given permission before it ran. JavaScript maybe.
