Zbot Infection

Dear Computer Lady,

I received an email from my ISP saying they have “identified that one or more of the computers behind your cable modem are likely infected with the Zeus Trojan/bot, also known as Zbot.”

I have run the recommended removal tools AND NIS Full System Scans, Power Eraser, Malwarebytes (free version) and Microsoft Safety Scanner. Zbot was not identified.

Is there any way for me to know for sure if this “infection” is present on my Windows 7 desktop computer? I am continually checking my bank account as I do online banking and everything is okay thus far. My ISP says there is nothing more I can do but suggests I might want to close my checking account and credit cards used for online shopping. REALLY? I am so concerned. Thank you if you can share your thoughts on this.

Sincerely, Kathleen

Dear Kathleen,

Your ISP is right about how dangerous the Zbot family of trojans is. According to Microsoft, “This family of trojans can steal your personal and financial information, and give a malicious hacker access and control of your PC. They can also lower your Internet browser security and turn off your firewall.”

However, your ISP is wrong when they say there is nothing more you can do. If this was my system, I would not feel comfortable using it until I had completely erased the hard drive (possibly even put in a new one) and install a clean copy of Windows.

Microsoft has more information about Zbot at:
