Clean Up Your Computer With These Utilities

ttt-logoEvery computer needs a tune-up now and then. Unfortunately computer viruses often disguise themselves as cleaning programs and other utilities. You think you’re downloading a legitimate program, but you end up infecting your computer instead.

Here are some of my favorite bona fide utilities to help you keep your computer in top condition. I’ve included the full address for each product as a reminder that links, even on a benevolent site like this one, can be hijacked by hackers in order to lead you to malware-infected sites. Always visit the manufacturer’s site or app store directly to download programs, and remember that you use these utilities at your own risk.

Also make sure you are running a reliable antivirus program, that you have current updates for your system installed, and that you have a recent backup. See each utility’s site for more information and support.

Useful Utilities For Windows

  • CCleaner from Piriform
    This program offers an easy way to clean out temporary files and other cached data. It also has options for optimizing your computer.
  • Malwarebytes
    One of the top products for virus and malware removal. Your regular antivirus program offers routine protection, but Malwarebytes can help you remove the sneakies that manage to infiltrate those defenses.
  • Personal Software Inspector from Flexera Software (formerly Secunia)
    If you’ve been looking for a convenient way to make sure all of your Windows programs are up to date, look no further. PSI scans your system and lets you know which programs need updates or are obsolete. No more wondering if you have the latest versions!

Useful Utilities For Mac

  • El Capitan Cache Cleaner from Northern Softworks
    This little gem lets Mac users clear out caches and other miscellaneous junk. You can also use it to repair permissions, which can help to mitigate problems, as well as run other optimization routines. Despite the name it also works with previous versions of Mac OS.
  • Apple Diagnostics (Apple Hardware Test) from Apple
    This hardware testing program is built into your Mac. Restart your Mac, then hold down the D key until the Apple Diagnostics window appears.
  • Disk Utility from Apple
    This is another built-in tool that helps you diagnose and repair hard drive problems. You’ll find it in the Utilities folder in the Applications folder on your Macintosh HD.


How To Protect Your Mobile Devices From Malware

ttt-logoMobile malware is on the rise, but few people maintain the same precautions on their tablets and phones that they do on their computers. Here’s what you need to do to stay protected.

Mobile devices need antivirus software just like any other computer, but watch for malware masquerading as antivirus. In general the same security rules we use for computers also apply to phones and tablets:

  • Use the latest version of your device’s software
  • Install all software updates
  • Back up your data
  • Install only well-known apps from known developers
  • Be wary of malware disguised as legitimate apps
  • When in doubt, don’t click

It’s a good idea to configure a passcode for your mobile device. You should also enable any “Find My Device” features your phone or tablet may have. You can configure most devices to erase any data after a certain number of incorrect login attempts, which will keep your information safe should your device become lost or stolen.

Remember that some threats are universal. A fake website that attempts to harvest your username and password can affect you whether you are viewing it on Windows, Mac, or any mobile device. You also need to use strong, secure passwords that are unique for every site, and enable two-factor authentication where possible.

Ransomware: A Dangerous Threat To Your Computer

Computer SecurityRansomware is a particularly nasty form of computer virus that encrypts your data, then demands an electronic ransom for the encryption key. Why is ransomware so hazardous, and how can you remove it?

Ransomware is vicious because it doesn’t just render your computer unusable. It encrypts all of your files, including those on networked computers, removable drives, and server volumes. To get the key to unlock the encryption, cyber-criminals demand that you pay. Ransomware has decimated businesses and consumers alike. It’s been around on Windows for ages (see my writeup of Cryptolocker from a few years ago), but recently the first Mac-based ransomware has appeared in the wild.

Should You Pay?
There’s some debate amongst computer security experts as to whether it is better to pay the ransom or not. Sophos’ Naked Security blog has a good overview of the discussion. They also have an excellent article on what you can do if you are infected by ransomware.

How To Avoid Ransomware
You are far better off avoiding ransomware in the first place. Start by making sure you have multiple sets of known good backups. A clean backup is one of your best protections against ransomware and other viruses. Below you’ll find my guide on backup options for Windows and Mac, including how to test your backups to make sure they work when you need them.

All of my usual security recommendations apply as well. Use a top-quality antivirus program, and keep your computer up to date. If you’re on an obsolete version of Windows or Mac, now’s the time to upgrade. Check your default security settings, and use strong, unique passwords on every site.

How To Protect Your Web Browser

browserYour Web browser lets you access Internet sites, but it can also be a gateway for viruses, malware, and more. Here’s how to keep your browser protected and secure.

(Don’t miss my latest article for The Northwest Herald – Protect Your Window To The Internet by Triona Guidry)

Remember that it’s vital to keep your browser up to date. If you can’t run an updated browser, you may need to consider an alternate browser or even a computer upgrade. Old computers running outdated browsers are holy grails to hackers and virus-writers because they’re so easy to infect. The US-CERT web site has detailed information about how and why you need to protect your Web browser.

Your computer’s default Web browser is Internet Explorer for Windows, and Safari for Mac. Here’s some information about how to secure them. Bear in mind that software manufacturers don’t provide security updates for outdated versions of their browsers, which may be why you don’t see yours here.

Internet Explorer (Microsoft)

Safari (Apple)

Alternate browsers include Mozilla Firefox, Google Chrome, and Opera, among others.

Cryptolocker: Why Modern Computer Viruses Are More Dangerous Than Ever

crypt-messageToday’s computer viruses go beyond mere annoyance. How does holding your data for ransom sound? What about spying on you through your webcam, tracking your physical location, recording every keystroke you make? Welcome to the modern generation of computer threats, where infection means real-world consequences.

The latest virus making the rounds is Cryptolocker, a textbook example of all the truly nasty ways in which a modern computer virus can ruin your day. Cryptolocker encrypts your data with a one-way algorithm which mathematically cannot be reversed. If you don’t pay the ransom within the timeframe, the only key to your data is gone, kaput, goodbye.

You can’t restore your data by removing Cryptolocker, because removing the virus doesn’t decrypt the data. No tech support person in the world can decrypt it for you because it’s simply not possible without the key. Even police departments have paid the ransom, even as they recommend that consumers not do so.

Here are some resources on Cryptolocker so you can keep it from digging its sharp claws into your computer.

Cryptolocker started its initial spread via email attachments, which are fairly easy to avoid. But now it’s morphing into variants that can be transmitted via USB drive, and luring victims with fake software activation codes. Although it’s a Windows virus, like all viruses it can be transmitted via Macs and mobile devices. Following in the steps of other viruses, soon Cryptolocker will evolve into spreading via social media sites.

And this is just the start.

There are other viruses out there that can activate webcams – and yes, they can bypass the green light that tells you the webcam is on. They can listen through microphones. They can track your location via your mobile device. They can listen in on your conversations on social media.

Now, more than ever, it’s vital to protect yourself from computer viruses. Here are some Tech Tips resources to help:

A Parent’s Guide To Protecting Your Kids Online

kidsIt’s hard to protect kids online, because parents and educators often have a hard time finding resources that can help them understand the latest risks and recommendations. I’ve gathered a variety of information in one place so you can learn about antivirus, parental controls, and protecting your kids while using mobile devices and video games.

Kids’ computers are among the most vulnerable to security threats. That’s not to say your kids are doing anything wrong. On the contrary, they’re the victims. Not only do virus-writers like to booby-trap kids with malicious web sites, they also like to infiltrate legitimate ones. Kids are also at much at risk of identity theft as any Internet user. More so, because cyberbullying has become such a deadly and devastating menace.

These are resources every parent needs to know about how computer viruses and Internet threats work. If you have questions, please feel free to comment. You can also subscribe to Tech Tips by email and follow on Facebook. You can also follow @trionaguidry on Twitter.

How To Avoid Keyloggers, Ransomware, And Rootkits

keyThe most advanced threats to your computer – keyloggers, ransomware, and rootkits – are also the most insidious. The best way to deal with them is to avoid them entirely.

Keyloggers come in hardware form, but are usually software viruses that secretly record everything you type. Ransomware holds your computer and its data hostage until you pay. Rootkits allow hackers to remote-control your computer, and are often used to introduce other types of malware.

So why should you fear these threats?

  • They bypass your security.
  • They steal your money and your identity.
  • They force your computer to infect still more computers.
  • They turn your computer into a spam-generating cog in the hackers’ profit-driven machine.

In the tech industry we say you’re rooted or pwned (like owned with a p – “powned”). In other words, the hackers own you. They own your accounts, your passwords, your address, your finances… your life.

Fake Antivirus Software
In particular, watch out for fake software scams. I’ve spoken of these before. Fake antivirus software tricks you into installing it, then bypasses your protections and invites its malware friends in to play. It’s devilishly hard to get rid of, as anyone who’s been infected can tell you. Usually you’re looking at a reinstall. And the darn stuff actually makes you pay to be infected! Talk about a scam.

This is why you don’t want to do a web search for “Windows antivirus” and start clicking on random links – many of them are poisoned results that lead you straight to the lookalike fakes.

Rootkits And Remote Admin
Concerning rootkits – those backdoor programs that allow hackers remote control of your computer – I’d like to point out that these are not the same as the built-in remote admin tools on your computer. A rootkit, by its nature, is designed to be stealthy. Remote admin programs are supposed to be used to maintain computers for legitimate purposes (say, if you are performing tech support on machines in a remote office). But it can also be exploited just like a rootkit if a hacker convinces you to turn it on. Check out this article on telephone tech support scams for an example.

Drive Imagers
Fortunately, you can make it easier to recover your computer if you do have to reinstall it – by imaging the drive while it’s still clean. This, combined with regular backups of your everyday data, will let you restore your computer quickly.

Cyber Attacks Spell Trouble For Consumers

padlock-phoneDo you know what to do if your account is swept up in a cyber attack? In the last year many popular sites, including LinkedIn, Twitter, and Evernote, have been attacked and consumer information stolen. What can you do to protect yourself?

As I said in my tech column in this month’s The Northwest Herald:

Cybercriminals attack big companies for the big prize: user account information. With email addresses and passwords in hand, they go on an account-cracking spree across the Internet, hoping that some of the users in their massive heist are using the same weak passwords on multiple sites. Itʼs likely some of your accounts have already been swept up in data breaches like this.

There are a number of things you can do to reduce the possibility of being hacked. Here are my recommendations plus related Tech Tips articles to help you with each step.

If your account has been hacked, you need to reset it. Here is information on account security and resetting hijacked accounts for some of the major sites:

And here is information on the recent breaches I mentioned:

Your Webcam Can Be Used Against You

webcamSmile! Your private life might be streaming live on the Internet!

Did you know hackers use viruses to commandeer the webcam on your computer, tablet, or smart phone? Makes you think about all the places you take these devices, and what they could be recording. In this month’s The Northwest Herald I talk about the dangers of unsecured webcams and microphones:

It’s not just your devices, but those of the people around you as well. Chances are, you’ve had a phone or tablet nearby during a private conversation with a lawyer, a doctor, a friend. What if someone else was watching and listening through that device?

Cameras can be hijacked in a number of ways. Cybercriminals can commandeer them with viruses, then extort you by demanding money for the deletion of potentially embarrassing photos and videos. Sometimes they have the nerve to imitate law enforcement, claiming that you have illegal content on your computer and will go to jail if you don’t pay their fee.

I’m fond of taping over the webcam unless you need to use it regularly – in which case a purse or pocket provides a lovely view of lint, should someone try to sneak a peek. That doesn’t help with microphones, of course, which is why it makes sense to store your mobile devices where they’re less likely to overhear private conversations.

I also strongly recommend to my fellow parents – get the computers and camera-equipped game consoles out of your kids’ bedrooms, NOW. There are some scary new statistics about the increase in predatory sexploitation which will make you want to take a hammer to every camera in the house.

Here are some articles about webcam security you might find interesting:
