Please let me know if this is the wrong board to post my question.
I had an infection from a Virus (Trojan Horse) which created the file scvhost.exe (NOT SVCHOST) in %windir%. Took me 4 hrs of painstaking work to remove it manually from the machine. But what i want to know is that why, even after latest updates and engine version (ZA Suite 6.5.737.000), was ZA not able to remove the virus after 3 thorough system scans? Does the antivirus lack the definition for the trojan? ZA did let me have the option of blocking scvhost's access to the internet, but didnt classify it as a trojan. Why?
