Threat secured

[C12]

Hi everyone, my computer was fine today and this evening suddenly I kept getting this popup.  I've run the Avast One smart scan, deleted my cookies and run Ccleaner.  Nothing appears to help?  Anyone have an idea what I can do to fix this, please?  Thanks for the assistance as I have two business Zooms on Wednesday and am worried that this popup will occur when I am in the meetings.

And if you click on see details

I clicked on see the details but can't remember what was said, sorry.  Will have to do so next time it pops up (as it popped up about five times before) so I attempted to open 20 websites and no pop up as yet .... typical!  LOL.

This attack could be transient in nature.  Malware is present for a short time and then removed by the malware author.

[EDIT:]  Avast One did not alert this time.

Was this the site you were trying to visit?

Site name was originally cdn.dreamdata.cloud but changed to the current url as hXtps://dreamdata.io.  Suspicious.

mchain, thanks for your reply and the information provided.  When the popup occurred, it only lasted for that day and I haven't seen it since. 

I don't think I was attempting to visit that website though?  I complete surveys and take part in focus groups, and enter competitions. I also perform user testing on websites and apps so it may well have been due to opening any one of those types of websites or possibly just clicking on something else?

Possible this was third-party cookie links that caused you to link to unseen websites linked to the site you were visiting.

If you are doing what you say, suggest downloading and deploying an adblocker on all browsers you use, as you cannot say or know what your website you are visiting is linked to what sites. 

Suggest uBlock Origin for all browsers, see:  https://duckduckgo.com/?t=ffab&q=uBlock+Origin&atb=v385-1&ia=web

mchain, at the moment, I have Adblock plus but I will download uBlock Origin thanks to your advice.

I downloaded uBlock Origin and it's great as I look at Daily Mail from time to time and the website wasn't asking me to whitelist it ... YAY!

Glad to help.

Having good adblockers and other security related add-ons will make your web surfing much safer.

Ergo, you can't click what you can't see, so chance of infection is lessened vs. visiting a site without protection.

Additional add-ons:

• Privacy Badger
• Safe to Open

etc., You can run as many add-ons as you need, and be aware time to load web pages should always be lower than when unprotected.  Just go to add-ons page for the browser you use, and enter 'security' for related protection.

Safe(er) surfing!
