Remove JS/Exploit-Blacole virus (Uninstall Guide)

JS/Exploit-Blacole (Exploit:JS/Blacole) is malicious Java code that exploits a vulnerability in the Java Runtime Environment component of Oracle Java SE and Java for Business that allows the execution of arbitrary code.
JS/Exploit-Blacole was developed in Russia and is used by hackers to infect computers with old versions of Java via malicious scripts planted on compromised websites. When the page is visited by a user running vulnerable versions of Java, the malicious Java class runs and allows the execution of arbitrary code.

In the wild, this exploit was observed to be distributed within a Java archive file named “g43kb6j34kblq6jh34kb6j3kl4.jar” and within a collection of other Java class malware, as in the following example list of files:

• ExtResolution.class [Detected as Exploit-Blacole]
• Image.class [Detected as Exploit-Blacole]
• Mover.class [Detected as Exploit-Blacole]
• TContainer.class [Detected as Exploit-Blacole]
• Zoom.class [Detected as Generic Exploit!c2w]

If your computer is infected with JS/Exploit-Blacole,you must assume that your passwords (for email, banking, or other online accounts) have been stolen, that any credit card details you have given in online transactions have been copied, that your bank account details (if you do online banking) have been stolen. You may have been used to send spam, your machine may be under the control of a botnet herder, you could still have malware running on your machine.
While most antivirus products will detect using their heuristic engine JS/Exploit-Blacole,some security products may have some issues while trying to remove this infection.
