It’s chiefly used to stop unwanted processes running at startup, but it’s also a brilliant tool for tracking down mysterious items that you didn’t install and whose role you don’t understand. One option is to use tools like the free startup manager Autoruns, which lists every single process, service and task that’s active or been active on your PC – including the malicious ones.

It’s unlikely to show up in manual malware scanners or even in a full antivirus scan. The Carberp Trojan is a great (well, notable) example of malware that’s being rebuilt over and over to make it much harder to detect. The new generation of stealth malware doesn’t tend to have obvious giveaway signs, such as weird pop-ups. Router botnetsĪ botnet is a series of internet-connected computers or other devices that hackers use to spread spam or malware to other PCs. In February, researchers identified ‘Locky’, ransomware that arrives courtesy of a malicious macro in a Word document. Office macros – small, configurable files that trigger an automatic series of actions – seem even more susceptible to ransomware infection, probably because users are prompted to download them. Word-hijacking ransomwareĪs if it’s not bad enough to find that an apparently safe file is actually a Trojan, security experts have now found ransomware hidden in Word files.

For example, a hacker can set malware to run during vulnerable periods like booting up, then to remain dormant for the rest of the time. Another evasion technique involves setting the malware to run at certain times or following certain actions taken by the user. Some malware, for example, hoodwinks antivirus programs by changing its server so it no longer matches the antivirus’ blacklist. Hackers are now designing malware whose main purpose is to evade detection. It remains hidden, allowing it to create even more backdoors for future use. Once the flaw is created, hackers can use it to control your PC remotely. Backdoors can be installed by Trojans, worms and other malware. Microsoft’s advice is that all rootkit infections should be dealt with by doing a clean install of Windows.Ī backdoor isn’t a type of malware, but a deliberately installed flaw in your OS that lets hackers into your PC completely undetected. Not only does it wrap an invisibility cloak around its dangerous contents, but it embeds itself so deeply into victims’ OS that they’ve been forced to wipe their systems to remove it. Once a rootkit has broken into your PC, perhaps by fooling you into clicking a phishing link, it hacks your OS to ensure its malicious cargo remains hidden.Ĭurrently the most frightening example is Popureb, “a small rootkit with a big reputation” according to security firm Sophos. If Trojans are malware in disguise, rootkits are smugglers embedded with malware.

It has terrifying new competition in the form of Carberp, whose name might make a child giggle but whose code could destroy all your PC’s defences.Ĭarberp’s source code has been released for free online – a terrifying prospect for computer security. The best-known Trojan in recent years is Zeus (also called Zbot), which went undetected in many PCs and plundered victims’ banking details. It now describes any strategy for invading a protected place – such as your PC’s operating system (OS) – by pretending to be something it’s not. Three thousand years later, ‘Trojan’ means much the same thing, but without the carpentry. The term, as you’d guess, comes from the ancient story of the Greeks who hid inside a wooden horse to sneak into the city of Troy. Trojans are malicious files masquerading as legitimate files, programs or updates.
