A few days ago, Malwarebytes detected a Trojan on my computer. After deleting it, I rebooted and after logging in, was met with a black screen (with the mouse). I then did a hard shutdown, booted it again, and everything seemed normal. However, I used Avast to perform another scan, and disovered that the Trojan was still there. I removed it, rebooted, and the issues seemed to be fixed.
But then, I discovered that there was no sound coming from either my headphones nor my speakers (laptop). Also, when using a browser (I tried both Chrome and Internet Explorer), Google would not load due to a problem with the security certificate not being trusted. This includes GMail. I checked out several things, none of which helped. I updated the audio drivers (Realtek) and checked the list of audio devices. The headphones aren't listed at all (not even under disabled devices), yet the speakers are (and are set as the default device). I also found that NO headphones/earbuds could be detected, and it isn't an issue with the hardware, plus the fact that Realtek detects them, but Windows doesn't ("No speakers or headphones are plugged in," error when hovering over what is normally the volume control).
I've experienced the sound issue once before (minus the Trojan), and I believe I just checked the computer again the next day to find that the problem was gone. I did a System Restore to about a week ago, to no avail.
Right now, I just want to make sure my computer is cleared of any malware before dealing with the sound and certificate issues. I'll create threads on those specific problems in their appropriate subforums once that's done.
