When I ended the process, AntiVir (Avira) stopped its online protection. I wonder why I need a "safer search" with an anti virus programme. I banned the process without problems on the system.

Avira had just finished an auto update when Comodo Firewall alerted me to apnstub.exe . I've never received this particular alert before, however I did just upgrade to the newest release of Avira Free Personal (version 10.2.0.696) last week. For now I blocked apnstub.exe. If Avira starts to go wonky, and no malware shows up in Malwarebytes or other scans, I'll probably allow it.

Here's some info about ApnStub.exe:

"Some of our consumers have expressed concerned about the application apnstub.exe which connect to the Internet after Avira AntiVir Service Pack 2 (SP2) Update is installed. Please be assured that this is a authorized and legitimate system-check utility.

After the download of SP2, your AntiVir software checks whether the ASK-Toolbar is already installed on your computer. If the Toolbar is already present, AntiVir will not bother you with a slide-up alert asking you to install it. The apnstub.exe utility will do this check three times (the next three times that you reboot your computer). An additional check is done whenever the AntiVir setup dialog is displayed, in order to once again confirm the presence or absence of the Toolbar. If the ASK-Toolbar is already present, AntiVir will not offer you the setup option for installing the Avira-Toolbar.

The technical purpose for apnstub.exe and connection to apnmedia.ask.com is the following:

(a) To check the requirements for Avira-Toolbar with operating system and browser configuration
(b) To check whether there is already an Ask-Toolbar installed
(b) To ensure that customers are receiving the recent Avira-Toolbar if no Ask-Toolbar is installed".

Please note that no further information is collected or passed along by the Toolbar, by apnstub.exe, or by apnmedia.ask.com.

It might be, that Ask ist just a search engine trying to compete with google, but I ABSOLUTELY don't like, when I'm forced over and over again to install something I didn't ask for! Nomen est omen - the company ASK should act like their name, it would be more successful, than sneaking in at each possibility.

This is a trojan from Ask.com that installs without permission when installing a lot of freeware apps. This is theft of services (computer time) and I will be filing a class action lawsuit against Ask.com.
