Čo značí toto bezpečnostné hlásenie?

Nepravidelne mi vyskočí bezpečnostná hláška (MDV 2009.1 upgraded z 2009.0), že je info vo var/log/security log; pod Krusader-rootom sa tam dostanem a je tam toto:

Z toho všetkého viem, že som do Skype/lang nakopíroval češtinu (ktorú som na ploche rozbalil a potom rovno do zmieneného adresára skopíroval): - /home/oooooo/Plocha/skype_cs.qm
- /home/oooooo/Plocha/skype_cs.ts
Po reštarte PC som to z plochy vymazal, aj fotky po uložení. Ostatnému vo výpise nerozumiem. Je pravda, niektoré písmená sa pri písaní zobrazujú neúplne (teraz sa mi ypsilon zobrazuje bez pravej hornej paličky ak je nad ypsilonom dĺžeň). A na gmaili mi spamer (IP asi Čína) vykradol databázu kontaktov a obťažuje ich reklamou.
Mám nejaké bezpečnostné poškodenia? Nesúhlasia kontrolné súčty?
