So, I have a client's computer that I cleaned a nasty Trojan off of. The Trojan was the fake AVG anti-virus (she already had the free, legitimate version of AVG installed, but had tried to buy the fake one when the warnings wouldn't go away). The Trojan caused some considerable frustrations to her system and was somewhat difficult to remove, but with a combination of Malware Bytes, a real AVG scan, and Spybot, I was able to remove all traces of the virus.
However, since the cleanup, my client cannot run any flash programs. She mostly wants to just play games but still, I'm trying to fix this for her before I invoice her for my work. The problem is, I've tried everything in my arsenal to get this fixed. I've completely uninstalled and reinstalled Adobe Flash Player three times and every time, I still get a message that I need to install Flash Player whenever I visit a site such as YouTube. I've also tried to update her Java but I'm still having the same problem. I'd would really like to get this fixed and I'm going to feel really stupid if this is a simple fix but I just don't know what else to try.
Any help would be greatly appreciated!! Also, this is a laptop and she is running Windows 7 Pro. The browser she is using is IE9 but I also installed Firefox and still get the same problem.
