Troj/ExpJS-IV is a Trojan that circulates via a compromised website of US Department of Labor. A subdomain of the main website of the Department, running off a separate server, what's known colloquially as a microsite, was changed to incorporate a malware infection, particularly Troj/ExpJS-IV. Troj/ExpJS-IV uses a malicious Java script file that involves what are known as anti-anti-virus techniques. This means that the attacker actively strives to avoid detection by interfering with the operation of one or more of the anti-virus software the computer user may be running. The malicious Java script, detected as as Troj/ExpJS-IV, even attempts to connect to the local web console to reconfigure the product on the PC user's behalf.
