My Windows Explorer crashes often. I received "Data Execution Prevention - Microsoft Windows." and it closes down. I also noticed that my internet connection isn't as fast as before. I ran an antivirus (Eset Nod 32) but I found nothing. I also ran Malwarebytes and also found nothing. I already sought help from "Malware Section" in this website's forum, done everything they suggested to fix it but unfortunately didn't solve the problem. I hope somebody could figure out what's wrong with my computer. Please help.
