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.

Security Basics For Windows Users

Windows81With Windows malware on the rise, now seems like a good time for a refresher on basic security advice for Windows users.

First, the bad news. If you are using Windows XP or Windows Vista, you need to upgrade as soon as possible for your own safety. Your computer can no longer run current antivirus software, nor does it receive security updates. Even longstanding programs like Google Chrome now consider WinXP and Vista obsolete. Below you’ll find resources on how to plan your upgrade.

As with any computer, the best defense for Windows users is prevention, including reliable backups and solid security software. Equally important, you also need to know how to recognize and avoid common Internet threats.

Windows Antivirus Programs
Good security starts with a quality antivirus program. You can use the freebies, but I strongly recommend that you invest in a commercial security suite. It’s money well spent.

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.

Windows XP Is Dead. Now What?

Windows XPAs you may have heard, Microsoft has ceased support for Windows XP. Many people assume it’s okay to keep using it. They’re dead wrong.

WinXP is already vulnerable to viruses because it’s been out so long. Now we have the nightmare scenario in which bugs are discovered but not fixed. Here’s how it goes: Microsoft announces a security vulnerability and offers patches for Win7 and Win8. The hackers rub their hands with glee and start testing to see if WinXP has the same vulnerability. Lo and behold it does, and they have an easy way to sneak into your computer.

Like the recently discovered Internet Explorer bug, which gives hackers a way to take over your entire system. It’s the first major vulnerability since XP’s demise. We know the bug exists in IE under XP. At first Microsoft said they weren’t going to patch it for XP, but now they’ve changed their minds. The question is, what about the next big bug? Using WinXP is like leaving your front door keys in the lock with a sign that says “Come on in, the best valuables are right over there!”

This isn’t a marketing gimmick or a way to increase PC sales, though I’m sure tech vendors don’t mind if you give them money. This is about you and the real-world repercussions of a hacked computer. Do you want your bank accounts wiped out? Do you want your identity stolen? Do you want your online identities hijacked? If not, then get off Windows XP.

Some of you will decide you don’t want to upgrade. That’s up to you, but I strongly recommend you reconsider. A very few of you – less than you think – will have some business-critical function that requires XP. Unless you are in that infinitesimal group, upgrade now.

What are your choices? Windows 7, Windows 8, or Mac. I did a rundown on them a while back based on a question from a reader. At this time, my recommendation stands at Windows 7 or Mac depending on your preference, with Windows 8 a distant runner-up due to its unfamiliar interface and lack of apps. Or, you could go pure mobile with tablet and smart phone.

For those of you who really, truly, honestly cannot upgrade from Windows XP, you have my condolences and some advice:

  • Use a browser other than Internet Explorer. Never use IE even for a moment.
  • Make sure you have the last round of updates Microsoft offered for XP. You can still use Automatic Updates to install them.
  • Run a good antivirus program.
  • Double-check regularly with Malwarebytes and CCleaner.
  • Don’t use Windows XP for finances or online purchasing. Ever. Your smart phone is safer at this point and I don’t advocate using smart phones for finances.
  • Don’t use WinXP to access social media sites (Facebook, Twitter, etc). Social media is a virus cesspool and you don’t have a lifejacket.
  • Plan your upgrade. This is not a permanent solution. Eventually your PC will fail and you will have to replace it.

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.

Hands-On With The Samsung Galaxy S4, Plus Antivirus For Android

galaxy-s4I recently had the opportunity to test-drive the Samsung Galaxy S4 from Verizon. If you’re looking for a powerful smart phone with some of the features of a tablet, this might be the device for you.

Related article: Galaxy S4: Vivid Color, Vibrant Performance by Triona Guidry (The Northwest Herald)

The Galaxy S4 looks similar to the Galaxy Note II, which I previously reviewed. In the hand it feels light and lively, matched by smooth performance when you use it. The 1080p Super AMOLED screen is unbelievably vivid even in sunlight, just the thing for entertainment on the go.

The S Apps are interesting, but I don’t know anyone who buys a device solely for the manufacturer’s add-on apps. If you want them they’re there, but as a recent article in Forbes asked, do people actually use these brand-name features? If you do, I’m curious to hear how you like them.

The Galaxy S4 is an Android device so you’ll get the full performance of Android 4.2 Jelly Bean plus the features available in the Google Play store. Just watch out for bad apps! Android is notorious for malware. You should run an antivirus program on any mobile device you use. For Android I am fond of Sophos’s Android security app. It’s free so there’s no excuse not to protect yourself.

Verizon is promoting its VZ Security service, which gives you antivirus plus SiteAdvisor for free, or antivirus, SiteAdvisor, and some other goodies for $1.99/month. Whether you pick Sophos, Verizon, or another product, please make sure you are running legitimate antivirus. Fake antivirus is skyrocketing on Android along with other malware.
