In fact, my LiteCoins stored in that wallet are already gone!  
 
But that's due to the fact that I changed my few Litecoins into BTC.
For some reasons, my primary wallet Jaxx refused to send them out. So I installed Electrum-Ltc on that day.  
The only worry I have now that both BTC-Electrum and Vialectrum on my Fedora-machine could be compromised.

Annoyingly enough, I do not have physical access to that workstation until next week. So I have to wait and see...
