A lot of software, drivers and firmware are yet to be properly updated for full compatibility with Windows 10. Until Avira comes out with an appropriate update or new version of the software you can expect to see some issues like this.
If this is a serious issue for you, you could try contacting Avira for information on upcoming updates.
Information here indicates that many consumer versions of Avira will not be compatible with Windows 10 - https://www.avira.com/en/support-for-business-knowledgebase-detail/kbid/1777 - perhaps best to find a more compatible piece of software.
EDIT: This answer is based on my experience of upgrading windows 7 and 8.1 systems with Avira installed to Windows 10. Whilst I did not see the specific error the user is reporting, I found that Avira demonstrated some incompatibility with Windows 10 (at least from an Upgrade to Windows 10 where Avira was installed in the previous version). Avira states that consumer versions of Avira Antivirus are not compatible with Windows 10, as can be seen from the link above.
