In the past 3-4 weeks I believe, I have been hearing random audio being played (even right now, it happened 3-4 times within 2 minutes or even less intervals.) It is usually music, audio, noise or sounds from video games, on-line or PC, or ranges from radio snips, and advertisement sounds. Frustrating. Also, my IE and Mozilla FireFox have been exceptionally slow on YouTube videos, Facebook Videos, and Typing on Twitter, and on YouTube Profiles (the typed words' appearances are delayed drastically.) Secondly, in the same time span, Pop-ups have been coming up, independently, using the Internet Explorer Browser icon on the top left corner. At first, I found this as a minor factor in my investigation, but soon I got tiresome of the pop-ups, and I un-installed my internet explorer web browser. To my surprise, it pop-ups up again (and again and again now-a-days) more frequently and STILL using the IE browser. That was when I deemed it worthy to ask for professional help... I am no good with computers.. I attached a hijackit log incase it is needed. **EDIT**: P.S., I forgot to say, I have over-due subscription from Norton Anti-Virus, so I stopped using it. I started using AVG 9.0 Free Anti-Virus, and also downloaded Malwarebytes' Anti-Malware, Spyware Terminator, and Ad-aware. I have went in 'Safe Mode with Networking' and did a full scan with Malwarebytes' Anti-Malware and Ad-aware. They found 2 Trojan Backdoors and terminated them. I thought that that would fix the problem, but it did not. The pop-ups and random audios (about 10-15 minutes ago) started to act up VERY frequently, with intervals smaller than 1-2 minutes... I really hope someone can help me, and quick. I really hope it isn't too late!!!! Thank you a tonne in advance!!! - Anthony.
