Slowing the compouter

Hello Sascha,
We regret for the inconvenience. We understand your concern. This is an known issue and it can be fixed by removing old traces of AVG program. We would request you to uninstall AVG using AVG Removal tool and then you can reinstall AVG program on your computer.

Please click on the below link to run AVG remover tool :
http://files-download.avg.com/util/tools/AVG_Remover.exe to completely uninstall your AVG program from your PC. Once you run the remover, please don't reboot your computer.   Download and run AVG Clear tool: https://share.avg.com/steam/PSP/AVG2017/AVG_Clear.exe. This tool will help with removing antivirus component of AVG 2017 and its traces.

Open tool
User Account control - click "Yes"
Windows safe mode - click "No" (we cannot recommend use the tool in safe mode, because there is a problem with compability)
Choose installed version (AVG Free, AVG Internet Security)
Click "Uninstall"
Click "Restart computer

after a recent update, AVG is slowing my computer. When i look in the task manager in the Apps section, AVG USER INTERFACE is using 30-35 % and in background processes AVG SERVICE (32 bit)  is taking more than 30% of the cpu…  why is this ?  

NOTE: Once the AVG Remover Tool has done with its process. Please go to the C drive and look for a folder named as "AVG Remover" and I request you to delete it manually.

Once you are done with the remover tool please try installing the AVG program by clicking the following link: http://files-download.avg.com/inst/mp/Internet_Security_1824.exe

Please check the CPU usage after reinstalling the program.
Thank you.
