Hello Avast, I just want to let you know that there’s a Trojan called T9000 which I call an “adaptable” trojan.
Trojan T9000 records all your video, audio, chats, Microsoft Office files, and more. Yet it’s also undetectable to traditional Anti-Malware products, including: Norton, McAfee, Bitdefender, and Kaspersky.
The installer for the T9000 trojan comes attached to common document files (called RTF files). When the document is opened, the trojan undergoes a sophisticated five-stage installation which to me threatens users privacy.
