Mirc ogni tanto assorbe il 50% di cpu

[manero478]

Scusate ho notato che ogni tanto MIRC assorbe il 50% e avvolte piu' della cpu,
solitamente dura qualche secondo (20/40) e poi torna tutto normale..(0/3)
Non noto nessun malfunzionamento del PC, ma siccome ho sentito che alcuni
mirc hanno delle "backdoor" che qualcuno usa per fare danni, non vorrei che fosse una di queste.

La versione del mio MIRCe' la ver. 6.16 con script INVISION 2 buld 3515.

Grazie per l'aiuto che saprete darmi.

ciao

Purtroppo non ho ancora la sfera magica per vedere cosa succede al tuo pc quindi iniziamo con il log di Hijackthis.

Usi mIRC per scaricare?
hai abilitato i ctcp?
I backdoor contenuti in alcuni script che vengono caricati da qualcuno di cui ci fidiamo aprendo conversazioni dcc possono essere usati da remoto.
Sta a te decidere con chi aprire questo genere di conversazioni per evitare questi problemi

per KAP :
si uso mirc per scaricare..
ctcp .. si avvolte lo uso

per Amantide ...ecco il log:

grazie

Il log sembra essere pulito.

Da una che non ha mai usato Mirc, non capisco una cosa però

Come mai i 3 processi mirc.exe che si trovano nelle cartelle diverse?
C:\Mirc irc.darksin.net\mirc.exe
C:\MIRC_ircdit\mirc.exe
C:\Mirc Horror\mirc.exe

Io ti consiglierei di scansionarli sul www.virustotal.com

[manero478]

i mirc sono 3, perche' ne ho 3 in esequzione..su diversi server..

ho controllato su www.virustotal.com .....i file sono puliti..

grazie e ciao
