Got a virus on win10 Pro despite having Bitfender and did not go to xxx websites

I just assembled my new system. Installed win10 Pro and Bitdefender Internet security trial version.
My intention was to re-install OS later anyway after all the tweakings are done.

I was using Edge, and the most "dangerous" web sites I've been to were some sites which show up in Google when I searched for "to who such actress was married", that kind of stuffs ...
However, to my surprise, today I saw in some instances my Edge tab was taken over by "rogers survey" scam, and the URL is zretailoutlet.xyz. I scanned my system with Bitdefender and it says my system is clean.

So now is the time for me to re-install my OS. But I am very bothered by the fact that I'm infected with Bitdefender on board and I did not go to any naughty web sites.
In the contrary, I have another in my living room with win 10 pro and a paid version of Bitdefender. And I went to numerous "dangerous" web sites and it did not show any sign of virus.
Any idea ?

Probably just a hostile JavaScript ad, and not an actual virus.

Install Malwarebytes, free, and do a manual scan. That should find the crapware hijacking your system, and let you delete it.

Oh, and stay away from "dangerous" sites. :)

You're just asking for it.

First, I used computers for almost 30 years now and never got a virus / malware, because I know a bit about common sense

Second, what bother me is that I installed Bitdefender and I did not go to any naughty website, so why did my new computer get it ?

I reinstalled windows since that was my plan but still I want to know what was wrong

From what I read you're probably not going to get a virus from the naughty sites. They have money and tight security. It's the mom and pop shop's who ask their niece/nephew to build a website for them and don't know what they are doing.

Could be XSS? Cross side scripting.

It popped up in almost any tab I was using. I regret did not capture the screen to show you. Basically it pretends to be a survey page from Rogers but the URL is all weird (zretailoutlet.xyz)

Anyhow now that I re-installed windows from scratch I switched to using Windows Defender and Chrome, instead of Bitdefender and Edge

Having a browser where you can stop javascript working by default is invaluable.

This.

Do your dangerous sites in a snapshot-ed VM. Restore snapshot after use. (and maintain / update the snapshot once a week or so...or automate this)
Place your VM host in another zone, and the zone should always VPN out (done on the router).

LOLs. I say JavaScript in the 'non-programmer, yet reasonably familiar with fake ads and scams' sense.

Remove Java from your system. Run Malwarebytes once a week, easy to setup, keep MB updated, and add Ublock Origin to your web browser if you don't already have it.

I agree with JAC. It's just an ad on the website. Don't be alarmed. Just close the browser and go to another website.

Lol. I am not too savvy with regards to the OWASP top 10 vulnerabilities, but I know the basics.

Java is not the samething as javascript. The user did not said he had install java. Javascript is run by all browsers internaly.

Canada, Eh!!
Surprised got thru trial version of BD as that should be same as paid version.

The built in AV of W10 is ok else suggest Kaspersky or Norton suites. If want AV only then Sophos or Eset.

Echo others to scan regularly with MBAM free and get Ublock Origin if comfortable with that.

For those that mentioned javascript... should that be blocked in browser settings? Especially on computers mainly used for banking and online purchases.

Do already block flash.

Thanks.
