New Ad Tabs Poping Up, C Drive Keeps Losing Space, Help Please

I'm not seeing any real issues in your logs. Perhaps you just have some bad addons hooked into Chrome and you should try resetting it back to defaults.

Reset Chrome to Defaults


And as far as your drive space goes, you have filled up your drive. You need to remove a lot of stuff from drive C. At least 20 GB minimum should be removed.

 

You need to free up a lot more space than that. You should really keep at least 10% of the harddrive size free for use by the system. Each time you reboot or install software upgrades, System Restore points are created. They can use from as little as a 100 MB to as much as 2 GB a piece. You need to look at what you are storing on your 465 GB drive that has taken up so much space.

Code:

  Datentr„ger ###  Status         Gr”áe    Frei     Dyn  GPT
  ---------------  -------------  -------  -------  ---  ---
  Datentr„ger 0    Online          111 GB      0 B         
  Datentr„ger 1    Online          465 GB  1024 KB         
  Datentr„ger 2    Online         7646 MB      0 B   

This is not a malware problem but rather a case of what you have stored on you drive. Also you have not cleaned up your TEMP folders!!!! Take a look at all the junk in C:\Users\Jo\AppData\Local\Temp and also in C:\WINDOWS\TEMP
