mein antivir taskmanger sagt das dazu: "Typ: Internet Explorer Object Status: Adware/Spyware"
Yeah, it could also be in the C:\windows\sysWOW64\ folder and infected along with msxmlm.dll (for 64-bit systems). To remove it do not--repeat--do not listen to these jokers on the net! Just run windows safemode or advanced startup repair and get a command (ms-dos) prompt and cd windows, system32 or syswow64 and delete the files; windows will never know the difference! The files themselves are not dangerous, the virus attaches to them using an update function and because these ms-xml dll's are classed as system files (or BHO's) for Internet Explorer, often can't heal/remove/del by av progs

Best practices for resolving msxml71 issues

The following programs have also been shown useful for a deeper analysis: ASecurity Task Manager examines the active msxml71 process on your computer and clearly tells you what it is doing. Malwarebytes' well-known Banti-malware tool tells you if the msxml71.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.
