My computer got "infected" with some sort of virus (setting manager).. i decided to download malwarebytes anti malware but ever since i "cleaned" my computer with this it is just not working right. First of all, the sound is gone. I can't hear anything if I try to play a video or music, and the video freezes and will not play. When I use google chrome, it runs very slow and then a message saying that Shockwave Flash (plug-in) is not working and ask if i want to stop plug-in. It doesnt work, whether i stop the plug-in or not. I can't download anything, I can't save anything, I can't print.
The person that fixed my computer the last time, installed Windows 8 but now it keeps asking me for a key or something (which i dont have) because the trial period is over--- Not sure if it has anything to do with it..
Help please!! I really need my computer to work! Thanks in advance.
