I think its related to Google^^ but i don´t have a clue what its doing
This program will notify you when you attempt to change the Internet Explorer search engine to something other than Google and asks if you would like to allow the change. This program, when run, will also connect to Google's servers and check for new updates to to the Google Notifier.

Zigh is correct, I believe to get rid of it, just uninstall the google toolbar. Since I use google a lot, I find the toolbar very useful. But keep in mind what zigh says about BHOs, and that they are used by spyware and adaware because your firewall doesn't recgonize it as anything other than it being your browser.

Google Noyifyer

Best practices for resolving swg issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active swg process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the swg.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
