A fatal error has been detected by the Java R

Bonjour,

voila, mon ordi me joue un sale tour depuis hier soir. Je cherchais un site pour regarder une série, j'ai vogué de site en site, j'ai des fenetres qui se sont ouvertes, et j'ai bien fait attention à toutes les fermer. J'ai finalement décidé de regarder un film sur mon ordi, un film que j'ai déja mais impossible. En fait, je me suis rendu compte que TOUS mes fichiers multimédia étaient bloqués, leurs noms ont été modifiés, ils commencent maintenant par "locked" et finissent par 4 lettres bizarres, exemple : locked-IMG_1967.JPG.nhnj.
En plus de ca, l'ecran de mon ordi s'eteignait, alors j'ai bougé la souris pour qu'il se rallume, je l'ai fait 2-3 fois, et finalement mon écran a affiché un message en plein milieu, disant que mon ordi etait bloqué et que pour le débloquer il faudrait que je paye une amende blablabla... je soupçonne un virus ou arnaque. Le truc c'est que je sais pas du tout comment marche tout ca! Et puis j'ai remarqué sur mon bureau "un rapport d'erreur" qui parle de java...
J'ai de perdre tous mes fichiers, alors s'il vous plait, aidez-moi!!!
Voila le rapport d'erreur que j'ai eu :
