Hackers or crackers or online criminals—whatever you call them—are working every minute of every day creating new malware that scam users more effectively. But most of these threats are new arrangements of old tunes. So with the right protection and a little savvy, you can avoid just about every digital threat you face.
(Note: This article is for busy Internet users who are looking for information on how to protect their PCs and their families from malware. For more about the technical side of malware, read Alia’s excellent series “A quick & dirty guide to malware”.)
What is the threat?
The first malware typically vandalized PCs and destroyed files. But since the early 2000s, the primary motive for malware creation has been profit. Online criminals are after your banking information or your credit card numbers or your computer’s processing power. In the worst case scenario, they may even be after private information that could be used to extort you or harm your business. And these sorts of attacks generally have both financial and psychological costs.
The true costs of malware can include your data, your content, your time, your effort and your heartache.
Want a few examples of malware mayhem? Spyware tracks you for advertising purposes and slows down your computer doing so. Keyloggers monitors your every keystroke in an effort to steal your credit card information. Scareware imitates anti-virus software in an attempt to extort a quick payment from you. Ransomware takes your files and demand a ransom in return. Rootkits can turn you PC into a zombie computer and use it to send out email spam or to host illegal materials or to join in attacks on websites. There’s even a malware that exists just to create a fake login page for your bank’s website to steal your account information.
How does malware end up on your PC?
Generally you end up with malware because you installed it. And whether you installed it or not, malware can only work if the program runs without being shut down or deleted.
Malware works like most scams — it requires some conscious or unconscious help from its victims. Thus online criminals have to know more than computer coding. They have to know what mistakes users are likely to make so they trick people who have probably NEVER fallen for a scam in their real lives. And the best criminals can convince even cautious users to make one wrong click.
How do you end up downloading and installing malware? Sometimes malware gets packaged in with more legitimate software. Sometimes simply clicking on a fake error message can trigger a drive-by malware download. And you’re certainly aware of the classic method of disguising malware in an email attachment.
You put yourself at risk when you’re downloading from a disreputable source or a peer-to-peer network of strangers. Seeking out “free” stuff on the Internet can cost you time and money. And this is especially true if you’re browsing and downloading without proper protection.
How to protect yourself from malware
1. Make sure your PC is updated and secure
I hope you’re reading this sitting down because I have quite shocking news for you: the software on your PC isn’t perfect. It may contain exploits or security holes that make it possible for your machine to be infected easily. Software companies know their programs are not perfect. That’s why they release updates. Microsoft, Apple and Adobe all release dozens of updates every year. You need to make sure you have these updates on your applications running or you’re increasing your risk of infection. Our free Health Check software is a quick and easy way to make sure your PC is protected.
Of course, we also recommend always running updated Internet security that includes anti-virus, spyware and firewall. Browsing Protection is another layer of security that can keep you from clicking on the wrong links. If you don’t have Browsing Protection, you can use ours. Check any link for free.
2. Be very skeptical of random pop-up windows, error messages and attachments
Modern browsers have reduced the burden of pop-up windows. But they do still exist. Most pop-ups are far more annoying than harmful. But you might think of pop-ups like broken windows into a neighborhood you were walking through at night. It’s a sign that you should be on guard.
Avoid clicking on any pop-ups that imitate your Windows error messages or error messages that come up when you try to close out of a page. (Force quit out of the program, if necessary.) If any software begins to install itself, close out immediately and run a scan of your Internet security software. You can also use our Online Scanner for free.
Avoid opening attachments at all unless you were expecting them and they come from a source you trust. If you can’t verify the source or feel anxious about a particular attachment yet have to open it, you can download it to your hard drive and have your updated Internet security scan the file before you open it.
3. Remove spam from your life
If you get a piece of spam, let your mail software know. Identify it as spam. You could also unsubscribe but unsubscribe link have been used on rare occasions to trigger a malware attack. Better to let your software handle it. If you have a friend on Facebook who spreads spam or bad apps, let them know. And if they continue spreading spam, unfriend them. You are responsible for your social network. Refuse to associate with those people who are not responsible for theirs.
4. Think thrice before installing any new software
Installing software should never be an impulse decision. Some people say think twice before downloading any software from a source you do not trust 100%. I say think three time.
At the very least, Google the name of a product you want to install. If you’re at all uncertain about whether to click download, consult with a tech savvier friend or your company’s IT guy.
When you install software, you could invite in a nasty predator that won’t leave until it’s done some serious damage. So think about installing software with a bit of the same sort of caution you use when deciding to let someone into your home.
5. Behave online as you would in real life
There’s an old saying in my family: “Don’t go licking the floors of a hospital.” What it means is: “Use your common sense.” You have a natural sensor in your brain that tells you when something feels dicey or unsafe. Trust your gut.
With the right software running and a willingness to step back when you feel uncertainty, you keep your PC and your life malware free.

Hacking is in the news. The U.S. recently disclosed that it was the victim of what may the biggest, most consequential hack ever. We hacked some politicians. And a group called "Hacking Team" was hacked itself. Brian Krebs reports: Last week, hacktivists posted online 400 GB worth of internal emails, documents and other data stolen from Hacking Team, an Italian security firm that has earned the ire of privacy and civil liberties groups for selling spy software to governments worldwide. The disclosure of a zero-day vulnerability for the Adobe Flash Player the team has used has already led to a clear increase of Flash exploits. But this story has a larger significance, involving serious questions about who governs who can buy spyware surveillance software companies and more. Our Chief Research Office Mikko Hyppönen has been following this story and tweeting insights and context. Reporters from around the world have asked him to elaborate on his thoughts. Here's a look at what he's been telling them 1) What is your opinion about the Hacking Team story? This is a big story. Companies like Hacking Team have been coming to the market over the last 10 years as more and more governments wanted to gain offensive online attack capability but did not have the technical know-how to do it by themselves. There's lots of money in this business. Hacking Team customers included intelligence agencies, militaries and law enforcement. Was what Hacking Team was doing legal? Beats me. I'm not a lawyer. Was what Hacking Team was doing ethical? No, definitely not. For example, they were selling hacking tools to Sudan, whose president is wanted for war crimes and crimes against humanity by the International Criminal Court. Other questionable customers of Hacking Team include the governments of Ethiopia, Egypt, Morocco, Kazakhstan, Azerbaijan, Nigeria and Saudi Arabia. None of these countries are known for their great state of human rights. List of Hacking Team customers: Australia - Australian Federal Police Azerbaijan - Ministry of National Defence Bahrain - Bahrain Chile - Policia de Investigation Colombia - Policia Nacional Intelligencia Cyprus - Cyprus Intelligence Service Czech Republic - UZC Cezch Police Ecuador - Seg. National de intelligencia Egypt - Min. Of Defence Ethiopia - Information Network Security Agency Honduras - Hera Project - NICE Hungary - Special Service National Security Kazakstan - National Security Office Luxembourg - Luxembourg Tax Authority Malaysia - Malaysia Intelligene Mexico - Police Mongolia - Ind. Authoirty Anti Corruption Morocco - Intelligence Agency Nigeria - Bayelsa Government Oman - Excellence Tech group Oman Panama - President Security Office Poland - Central Anticorruption Bureau Russia - Intelligence Kvant Research Saudi Arabia - General Intelligence Presidency Singapore - Infocomm Development Agency South Korea - The Army South Korea Spain - Centro Nacional de Intelligencia Sudan - National Intelligence Security Service Thailand - Thai Police - Dep. Of Correction Tunisia - Tunisia Turkey - Turkish Police USA - FBI Uzbekistan - National Security Service 2) What happens when a company of this kind is a victim of an hacking attack and all of its technology assets are published online? This was not the first time something like this happened. Last year, Gamma International was hacked. In fact, we believe they were hacked by the same party that hacked Hacking Team. When a company that provides offensive hacking services gets hacked themselves, they are going to have a hard time with their customers. In the case of Hacking Team, their customer list was published. That list included several secretive organizations who would rather not have the world know that they were customers of Hacking Team. For example, executives of Hacking Team probably had to call up the Russian secret intelligence and tell them that there's been a breach and that their customership was now public knowledge. The Hacking Team leak also made at least two zero-exploits public and forced Adobe to put out emergency patches out for Flash. This is not a bad thing by itself: it's good that unknown vulnerabilities that are being exploited become public knowledge. But Adobe probably wasn't happy. Neither was New York Times, as they learned that Hacking Team was using a trojanized iOS app that claimed to be from New York Times to hack iPhones. 3) Is it possible to be protected from malware provided by companies like Hacking Team? Yes. We've added detection for dozens of Hacking Team trojans over the years. Hacking Team had a service where they would update their product to try to avoid signature-based antivirus detections of their programs. However, they would have much harder time in avoiding generic exploit detections. This is demonstrated by their own internal Wiki (which is now public). Let me attach a screenshot from their Wiki showing how we were able to block their exploits with generic behavioural detection: Cheers, Sandra [Image by William Grootonk | Flickr]
Time to update Adobe Flash if you use it. So if you do, do it now. Of course, it always feels like time to update Flash. As an internet user, it's become all of our collective part-time job. It's a reminded that while the software is free, your time isn't. This particular update was necessitated by an event you may have heard about. "The flaw was disclosed publicly over the weekend after hackers broke into and posted online hundreds of gigabytes of data from Hacking Team, a controversial Italian company that’s long been accused of helping repressive regimes spy on dissident groups," Brian Krebs explained. The Hacking Team hack raised interesting questions about government surveillance and helped rattle nerves this week as computer systems kept planes out of the air and shut down the New York Stock Exchange -- freak incidents that are completely unrelated, according to disclosures thus far. But it doesn't take events like this remind us Flash exploits are so common that they're part of the business model of criminal operations like the Angler exploit kit. The key to security is always running the latest version of everything. So how do you get yourself out of the business of constantly mitigating Adobe Flash risks? Here are three ways. 1. Quit it. This is Brian Krebs' solution. He's lived without it for more than a month as an experiment. "It is among the most widely used browser plugins, and it requires monthly patching (if not more frequently)," Krebs said. And did he notice life without it? "...not so much." So instead of updating, you can just get rid of it. 2. Auto-update. If you're going to keep it, this is the minimum precaution our Security Advisor Sean Sullivan recommends. This will make sure you're getting all the updates and will prevent you, hopefully, from being tricked into downloading malware posing as an update. So turn those "background upgrades" on. 3. Click-to-play. If you're doing number 2, you probably want to do this too. Click-to-play means Flash elements run when you tell them to. Here's how to do it in all your browsers. Not only does this expose you to fewer risks, it makes the internet less annoying and can make your browser quicker. So why not? So what did you choose? Let us know in the comments. Cheers, Jason
“The cloud” is a big thing nowadays. It’s not exactly a new concept, but tech companies are relying on it more and more. Many online services that people enjoy use the cloud to one extent or another, and this includes security software. Cloud computing offers unique security benefits, and F-Secure recently updated F-Secure SAFE to take better advantage of F-Secure’s Security Cloud. It combines cloud-based scanning with F-Secure’s award-winning device-based security technology, giving you a more comprehensive form of protection. Using the cloud to supplement device-based scanning provides immediate, up-to-date information about threats. Device-based scanning, which is the traditional way of identifying malware, examines files against a database saved on the device to determine whether or not a file is malicious. This is a backbone of online protection, so it’s a vital part of F-Secure SAFE. Cloud-based scanning enhances this functionality by checking files against malware information in both the local database found on devices, and a centralized database saved in the cloud. When a new threat is detected by anyone connected to the cloud, it is immediately identified and becomes "known" within the cloud. This ensures that new threats are identified quickly and everyone has immediate access to the information, eliminating the need to update the database on devices when a new threat is discovered. Plus, cloud-based scanning makes actual apps easier to run. This is particularly important on mobile devices, as heavy anti-virus solutions can drain the battery life and other resources of devices. F-Secure SAFE’s Android app has now been updated with an “Ultralight” anti-virus engine. It uses the cloud to take the workload from the devices, and is optimized to scan apps and files with a greater degree of efficiency. Relying on the cloud gives you more battery life, and keeps you safer. The latest F-Secure SAFE update also brings Network Checker to Windows PC users. Network Checker is a device-based version of F-Secure’s popular Router Checker tool. It checks the Internet configuration your computer uses to connect to the Internet. Checking your configuration, as opposed to just your device, helps protect you from attacks that target home network appliances like routers – a threat not detected by traditional anti-virus products. So the cloud is offering people much more than just extra storage space. You can click here to try F-Secure SAFE for a free 30-day trial if you’re interested in learning how F-Secure is using the cloud to help keep people safe. [Image by Perspecsys Photos | Flickr]
