BleepingComputer.com: Wave sound lower itselfs sometimes? often when cam active

Hi everyone on bleepingcomputer
Just noticed that my WAVE sound & MASTER volume in sndvol32 lowers itself to the bottom sometimes
got no strange processes running(what i could see with process explorer) but im not that experienced

Been running malwarebytes antimalware, superantispyware free full updated and scanning everything in system(y'
Also Sophos antirookit and GMER and nothing red lined found either

Would be so thankful if anyone could take a deeper look in my system? and maybe come to an conclusion on why the sound lowers itself
often when im starting or inviting an Cam request on Live messanger 8.0.17


What i think it couldve bee some kind of trojan that listening my sound from cam or so?
WAVE & Master volume both being lowered to maximum and im using highspeakers so no headset or like that


Thanks everyone

Hello.

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:

• Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  
• Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  
• The Express scan will automatically begin.
  (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  
• If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  
• If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)

• After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  
• In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  
• Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  
• Please be patient as this scan could take a long time to complete.
  
• When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  
• Click Select All, then choose Cure > Move incurable.
  
• In the top menu, click file and choose save report list.
  
• Save the DrWeb.csv report to your desktop.
  
• Exit Dr.Web Cureit when done.
  
• Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  
• After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
