Verifica post-pulizia scareware polizia

[Zane]

Ciao ragazzi,
ho appena ripulito un PC per un amico, infettato dallo scareware a tutto schermo che blocca il sistema ed esorta a pagare la multa alla polizia.

Per favore, mi confermate anche voi che il sistema è ok?

Grazie!

Hijackthis non lavora bene su sistemi a 64 Bit: sarebbe più utile poter consultare un log di HitmanPro ed uno di Malwarebytes Anti-Malware.

P.S.: Il log sembra pulito.

[Zane]

Grazie Hash,
il "problema" è che nè mbam, né hitman trovano niente, così come avast (l'antivirus residente). Avira Rescue System va invece in segfault, non so perchè.

Stando così le cose, cercavo appunto anche un'opinione "umana"

[crazy.cat]

Si tratta di Windows 8 in quel pc?

Se è ripartito il sistema direi che se ne andato, comunque molto meglio Kaspersky rescue disk per queste scansioni, si è sempre aggiornato e ha sempre trovato il problema.

Se non ricordo male C:\Program Files (x86)\McAfee Security Scan\3.0.318\SSScheduler.exe è parecchio inutile.

Nel log non si vede niente.

[Zane]

Sì, Win8. Domani uso Kaspersky, grazie

[Zane]

Tutto ok anche con Kasperky. Il malware, comunque, non si manifesta più. mah!
