Think your security is taken care of with a frequent anti-virus scan? Think again. While we’ve all become used to the idea that viruses, worms and other malware - however much disruption and damage they cause to our systems - can be detected and removed thanks to the tracks they leave as they create havoc, that’s no longer something to count on. Proving the point is Poweliks, an invisible trojan horse that evades being picked up by anti-virus software. Read on to find out all you need to know about Poweliks and how to fight it.
What is Poweliks?Security firm Symantec describes Poweliks as a trojan horse that performs malicious activities on the compromised computer. But it’s no ordinary trojan - unlike the majority, which infect your computer with malicious files, Poweliks is a silent and invisible threat that hides away in the memory registry of your system. It’s not entirely new for a virus to seek to cover its tracks by making itself "file-less" but, in contrast with Poweliks, most are wiped when you restart your computer and its memory is cleared. Worse still, Poweliks hijacks the legitimate processes and applications running on your network, inserting its code into them where it can largely evade detection.
