Hello, I'm new here and certainly not a technical expert. But I have a problem: For quite a while I have a fake Adobe Reader Updater running on my laptop: Every time I boot or open a PDF file it pops up and asks me to install the Adobe Reader Update which " solves user made comments on security leaks and other issue"s, after installing the system has to be rebooted". Last week I had a complete re-install of my laptop. Before that my provider ran the "update" and it certainly was trojan with all kinds of pop ups etc. But as said, the hard disk was formatted, XP re-installed and back up data wereput back on the system.... To my own amazement the thing just pops up again after the first boot of the system. Meaning that it either "sits" in the back up data or somewhere resident in the system memory or something. As long as I don't install the thing there is no problem, but I would really like to get it out of the system. I ran all kinds of malware finders like Malwarebytes, Spybot, AVG online scan.... no result.. So..is there anyone who knows about this problem and who has a solution?
