My pop-ups occured on a PC. My Mac Pro has, so far not exhibited similar behavior. I am using Firefox as a browser on both machines, and "block popups" is ticked on both machines. I have definitely not accessed any gaming sites or any such thing, and as I reported, the first pop up occurred right after spending time on the forum.
playz123 - "Block popups" won't work depending on how the popup is coded but I am not getting any popups. I suspect the site that created the popup was a site that you visited besides vi-control in the same browsing session. I have seen some news sites (many which look reputable) and unreputable search engine splash pages create popup windows in that manner, and most open behind your current window so you do not see them until far later.
I worked in IT for many, many years and have seen almost with every single change a 'change syndrome' where any change is made and any completely unrelated issue that an end user has is blamed on the change, it is due to people's innate fear of changes causing issues. Only in a small percentage of cases are those issues actually related, and in most cases they are coincidental. I believe this is what we are seeing here.
The simple logic is that these popups would be happening to many more users if they were actually caused by this site. The low number of reports is suggestive of an unrelated coincidental issue rather than some underlying site issue.
There is a bit of a test you can do:
1. On your PC, open your browser and browse around to a bunch of different sites that you visit besides vi-control. Close your browser and see if a popup has triggered.
2. Open your browser and visit only vi-control, browse around for a while, do some things, and close the browser without visiting any other sites (even in other windows). Close it and see if a popup has triggered.
If both 1 and 2 trigger popups, the issue is either some kind of adware in the browser, or some toolbar that is installed, or the start page (some software installers change your start page to an unreputable one, java updates are notorious for changing start page to ask.com which might give you banner ads).
If only 1 triggers popups, it is obviously a different site that is triggering the popups.
If only 2 triggers popups, it's still unlikely to be caused by this site, but it becomes a possibility. However, it would have to be some part of the site that most people are not using, or some particular post, that is triggering the popup.
If neither triggers popups, it was probably a different site triggering the popups that you visited the last time this happened.
You can also revisit your steps through the sites when this happened by going into your browser history. Going through the pages you visited one by one can potentially lead you to which one created the popup.
BTW, Greg- your issue is highly suggestive of either installed malware (sometimes posing as a browser addon, check chrome add ons if you use chrome, or firefox addons if you use firefox, etc.) a rootkit infestation, which means it can be cloaked and undetectable by most software. This is a very serious issue. Malware in the form of browser addons (perhaps posing as toolbars) have the ability to rewrite links to redirect them to advertisements or the wrong site when you click on them (when you go back and click on it again, it opens in the correct site); alternatively, they can open a popup in addition to what they are supposed to open. Malware in the form of rootkits is much worse - it has the same behavior but operates in all web browsers and can be quite tricky to remove because they can make themselves invisible to scans. There is a site called "Bleeping Computer" which provides free support for rootkit removal (not sure if they help with OSX as well though).
