Exterminate It! Antimalware


Known threats:700,086 Last Update:March 16, 12:51


Dear Jean,

Thank you for your follow-up. I did indeed use the Submit State feature last night and this morning, your team sent me instructions to run an 'update' and then re-run Exterminate It! on the PC. I just finished that process and the new update wiped it out. I ran my regular anti-spy/anti-virus to double-check and it wasn't able to detect it either. I appreciate the support from both you and your team.

Linda D.
