Earlier today, a friend of mine came to me complaining about no longer being able to access his web e-mail service that used Outlook 365. It worked on my laptop and my desktop, so it was a problem with his computer. I accessed his computer and attempted to use another browser. He originally was using Firefox and I went to use IE. It at first didn't work, but then I selected "Reset..." to reset literally every setting to default installation properties. I then tried to access Outlook 365 web e-mail and to my surprise it worked.
At this point, I knew it was browser issues, not a firewall issue or anything like that. After messing around with firefox's security settings, I tried disabling all extensions, to no avail. I then looked at the add-ons and saw something called "Web Security Keeper". It linked to a website that I will not post here for security reasons.
After doing some research, I see LITERALLY NOTHING on the web about this website or this add-on to firefox. I removed the add-on and suddenly everything worked flawlessly. If you look on the website, it is so poorly coded / vulnerable that it cannot possibly be a professional site. Furthermore, the "Download" button doesn't actually do anything as far as I could tell.
My friend had completely updated browsers/MBAM/Comodo Firewall/ESET NOD32 and isn't stupid. He also hasn't downloaded anything in 2 weeks and he has no idea where it came from. Does anyone have any information on this "add-on" ?
