G injects code into web browsers and other applications that access a network, and in many cases causes them to crash. Here are some examples of users posting logs on forums about certain applications crashing.
This malware patches web browsers and network applications essentially to search for user names and passwords. It looks for a number of domains — websites such as Google, Yahoo! Presumably, the people behind this malware are looking for both user names and passwords that they can immediately exploit — such as for a bank website — as well as others that may be reused on different sites.
One of the clues that a Mac is infected is that certain applications will crash. This is notably the case for web browsers, such as Safari, or other network programs, such as Skype. This is because the injected code interferes with the program making it unstable. This malware also has an automatic update module that checks a number of websites for new versions. Most of the cases of infection we are seeing are on Macs running OS X It is therefore essential that anyone running OS X To do this, run Software Update, from the Apple menu; if you do not have the latest version of Java, an update will be available.
So here's a quick FAQ on the Flashback Trojan, including information on what it is, how to tell if you have it, and steps you can take to get rid of it. What exactly is Flashback? Flashback is a form of malware designed to grab passwords and other information from users through their Web browser and other applications such as Skype. A user typically mistakes it for a legitimate browser plug-in while visiting a malicious Web site.
At that point, the software installs code designed to gather personal information and send it back to remote servers. In its most recent incarnations, the software can install itself without user interaction. When did it first appear? Flashback as we know it now appeared near the end of September last year, pretending to be an installer for Adobe's Flash , a widely used plug-in for streaming video and interactive applications that Apple no longer ships on its computers.
The malware evolved to target the Java runtime on OS X, where users visiting malicious sites would then be prompted to install it on their machine in order to view Web content. More advanced versions would install quietly in the background with no password needed. How did it infect so many computers? The simple answer is that the software was designed to do exactly that.
In its initial incarnation, the malware looked very similar to Adobe's Flash installer. It didn't help that Apple hasn't shipped Flash on its computers for well over a year, arguably creating a pool of users more likely to run the installer in order to view popular Web sites that run on Flash.
In its newer Java-related variants, the software could install itself without the user having to click on anything or provide it with a password. What also didn't help is the way that Apple deals with Java. Instead of simply using Java's current public release, the company creates and maintains its own versions.
As it turns out, the malware writers exploited one particular vulnerability that Oracle patched in February. Apple didn't get around to fixing its own Java version until April. What has Apple done about it? Since Flashback's launch, the security tool has been updated twice to identify and protect against a handful of Flashback variants.
A more recent version of the malware, however, got around XProtect by executing its files through Java. Apple closed off the malware's main entry point with a Java update on April 3 , and has since released a removal tool as part of a subsequent Java update. For this, we suggest downloading and installing a computer program such as Reimage Intego. Flashback virus - a Trojan horse which enters the computer system as a fake Adobe Flash Player.
Performing the Flashback trojan removal requires a big variety of skills. This is the main reason why the Trojan horse cannot be eliminated by using manual technique.

Flashback virus seems to be extremely malicious as it is very hard to terminate.
According to cybersecurity researchers, once the malicious attacks had emerged in the past years, Apple decided to release Java Runtime Environment JRE which would be a way to deal with the dangerous malware and would be available not only on Mac but also on other operating systems such as Windows, Linux, and Solaris. However, the release did not come out and did not stop the trojan from infecting numerous Mac users in Flashback trojan - a malicious virus which infects Mac users.
