Malware/Ad Popup on one particular site

[pbcsd]

So have been struggling with a really odd issue. When I access one site on the web, one that I use a lot (www.avsforum.com), a few days ago out of the blue, after a minute or so the website would change to a spoof site claiming to be McAfee and that I had a virus, should scan the computer, etc. I ignored it, ran Malwarebytes, which found some Altruistics thing on my laptop and quarantined it. Checked my Chrome Extensions, nothing unusual there. Went back into Chrome, and boom, same thing happening.

Then tried another malware remover (HitmanPro), found some stuff Bytes didn't, but still didn't help. I then did a Tron job (via Reddit) which is supposed to be a much more invasive scan and removal tool. Also didn't help.

Finally, installed an adblocker extension (uBlock Origin Lite), and it seems to be blocking the ad from popping up as it doesn't happen anymore. But if I turn off hte ad blocker, it comes right back, and I'd rather get rid of the culprit.

Weird thing is...I tried Microsoft Edge which is a browser I never use, and received a different issue, with teh exact same site. Basically also results in a pop up except a different looking one (see both below).

At a bit of a loss to know how I can get rid of whatever it is that is causing this?

Hello..! Welcome to MalwareTips..!

My name is icotonev and I'm here to help you remove malware ..! Before we begin, please note the following:

• First, please keep in mind most of us at MalwareTips volunteer our assistance for your benefit in your time of need. Please try to match our commitment to you with your patience toward us.Logs from malware diagnostic or removal programs can take some time to get analyzed. Also, have in mind that all the experts here are volunteers and may not be available to assist when you post. Please, be patient, while I analyze your logs.
• It is important to not run any tools or take any steps other than those I will provide for you.Also, do not uninstall or install any software during the procedure, unless I ask you to do so.
• Cracked or pirated programs are not only illegal, but also can make your computer a malware target. Having such programs installed, is the easiest way to get infected. Thus, no need to clean the computer, since, soon or later, it will get infected again. If you have such programs, please uninstall them now, before we start the cleaning procedure.
• Please perform all steps in the order they are listed. If things are not clear or you experience problems be sure to stop and let me know.
• Please attach all logs into your post unless otherwise requested.
• When your computer is clean I will let you know, provide instructions to remove tools and reports, and offer you information about how you can combat future infections.
• If you do not reply to your topic after 3 days I will assume it has been abandoned and I will close it.

Please follow the following instruction ..:

Download Farbar Recovery Scan Tool and save it to your desktop. --> IMPORTANT

If your antivirus software detects the tool as malicious, it’s safe to allow FRST to run. It is a false-positive detection.
If English is not your primary language, right click on FRST.exe/FRST64.exe and rename to FRSTEnglish.exe/FRST64English.exe

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

• Double-click the FRST icon to run the tool. When the tool opens click Yes to disclaimer.
• Press Scan button and wait for a while.
• The scanner will produced two logs on your Desktop: FRST.txt and Addition.txt.
• Please attach the content of these two logs in your next reply.

---------------------------------------------------

In your next reply, please include:

• FRST.txt
• Addition.txt
