I did the steps to remove Dropper but it was a partial solution, now I am being attacked by another trojan called Agent_r.AKS, it is very mailiciosous virus
this do the following
1) disabled all the AVG components
2) disable full scan though this option is not shadowed
3) put your supplicant mode out of the wireless connection
4) files affected: locacion: C:\WINDOWS\system32\lsass.exe (776)
Please sci123 hurry to help me remove this threat manually because AVG can't delete or send it to the vault.
I will stay tuned through Linux until this problem be fixed
