NIS2010 is not accessible, looks like works in the background thou

yesterday my NIS 2010 did not appear in the tray icons; at the same time Avira recognised and deleted TR/crypt.xpack.exe on the camera SD card. I tried to open the NIS from the desktop - did not work. Ran the full scan by Avira - looks good. This morning NIS 2010 full scan was pre-scheduled and actually ran (from the background?) - some cookies, but nothing serious. Still can not open NIS to see if it has been up-to-date, and when trying to open Norton File Insight - Erroe comes up "Problen detected: Unable to launch.

 

I do have Avira on the same computer; for couple years they lived together fine. Started blocking each other? I disabled Avira for a minute, but NIS wouldn't open anyway.

 

Should I maybe reinstall NIS or... is there a trojan threat and a major cleanup needed?
