v5.28.6005(64-bit) kills Avira icon in Notification Area in Win7

We are running several rigs (all Win7).

On each two users (one with ADMIN rights and one without).

We can reprocude it, on ALL rigs, every time we:

1) power up PCs

2) logon to ADMIN

3) execute CCleaner

4) logoff from ADMIN

5) logon to USER

6) --> Avira icon in Notification Area will not show up ...

Solution:

do a re-logon to USER.

BUT this solves the problem not every time.

Only a power off/on will always do the job.

For those who are now wondering and want to point out or ask the following:

There is no arrow in the Notification Area to click on, in order to re-activate the icon.

Checking the Task Bar properties shows that the Avira icon is set to "Show icon and notifications".

AND, yes,

unticking the "AntiVir Desktop" option under Utilities in CCleaner solves this behavior.

BUT,

is it actually a new bug, or just a new feature under v5.28.6005?

Have a nice day ...

We are running several rigs (all Win7).

"we" as in several people in your house or "we" as in several people in your business?

I remember an antivirus from years past (WinXP era and newer) where any logging off, and then a logon would cause it's SysTray icon near the clock to completely disappear. I can't remember if it was Avira or not but the solution was to always restart the computer. Other antivirus' can also have that behavior without CCleaner being the culprit, however you've tested it to be caused by CCleaner.
