PWS:Win32/Zbot.gen!AF is a malicious Trojan that is involved in a malicious ACH debit transfer malware spam campaign and targets Automated Clearing House (ACH), is the e-network in USA that processes financial transactions. by sending the fake emails to web users' mailboxes. The bogus emails with different captions that refer to ACH come from various IDs that are spoofed. All the fraudulent emails include one web-link, which allegedly gives the additional details of the transaction. If the email recipient clicks on the malicious link, his/her web browser tries to access infected websites that ask the PC user to immediately download and install Adobe Flash Player. These websites download the website of Adobe that serves the update. However, the download provided in a file named 'flash.exe,' installs PWS:Win32/Zbot.gen!AF. Once a computer system is corrupted by PWS:Win32/Zbot.gen!AF, it tries to make a connection with the Internet Protocol address 64.252.17.231 on the 11760 port, possibly for telling its creator that the affected PC system has been infected. If you receive the unsolicited email related to ACH that contains a web-link and malicious file, do not click and open it to protect your PC from PWS:Win32/Zbot.gen!AF.
