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.

Readers Ask: Sending DOCX Files To Macs, Troubleshooting Slow Web Sites, Choosing New Computer Hardware

computer-booksI’ve been talking with Fr. Jack Sweeley about whether he should move to Windows 7, Windows 8, or a Mac. After our initial discussion, he had some followup questions, which I am posting with his permission:

Thank you so much, Triona. This is very helpful. However, I have a few questions.

1. As I stated, I have several books written and others in process as well a hundreds of commentaries all written with Word using VISTA. Will I be able to open and edit these on a Mac?

2. From time-to-time I have sent documents I have written to someone who at that time had a Mac and they told me they could not open what I sent written in WORD on a PC. Is this still the case?

3. Contrarily, will I be able to open documents sent to me in WORD using a Windows PC on a Mac?

4. RE Macs: Could you give me comparisons between hard drive space on a Mac v. PC (is a gig a gig on both), for processing speeds what are the terms used and are they the same for a Mac and a PC, what are the terms used for memory and are they the same for a Mac and a PC?

5. What amount of HD space, processing speed, and memory do I need to do what I described in my original letter? I am impatient and go crazy having to wait for Websites to load especially when I have 8-10 sites open at the same time.

6. I know a little about the landscape of PCs and once I know what parameters I am looking for I can find one. However, I have never even looked at a Mac to say nothing about being able to compare them. So, could you cite different kinds of Macs–with their price ranges for what I need–and the pros and cons of each.

Let’s look at Fr. Jack’s needs and see how we can help him.

Opening Word For Windows .DOC and .DOCX Files On Macs

wordmacYes, you can open Word documents, both .doc and .docx, on a Mac. Apple’s word processor Pages (paid; via App Store) can open both but saves in its own proprietary .pages format. NeoOffice (donationware, www.neooffice.org) can also open both .doc and .docx but again, it saves in its own .odt format. You can spring for Microsoft Office for Mac (paid; via Microsoft), which is the most expensive option but can handle Word .doc and .docx files without conversion.

The person to whom you sent the Word file may not have had a recent Mac word processing program, or did not have Microsoft’s free .docx converter installed. You can either make sure all Word files are saved as .doc and not .docx (.docx is default from Word 2007 onwards), or make sure the recipient can convert .docx. Don’t go looking online for free converters, use the genuine ones from Microsoft to avoid viruses.

For the most part, Word, Excel, and PowerPoint files can be used interchangably between PCs and Macs. The main exception is if you have code in Visual Basic (VBA) or custom macros not supported by the Mac. Everyday documents work fine, and on the rare occasions they don’t, the one-time installation of a converter tool usually fixes the problem.

Now, if you have print-ready files, a Word document just is not a proper layout tool. Better to save final drafts to PDF which will keep the pagination you want. Professionals do document layout with industry standard tools like Adobe InDesign and Quark.

When it comes to file types and permanent storage – as in, stuff you want to keep longer than the software program that created it – I am a fan of good old RTF, or rich text format. It’s a universal file type that allows formatting like bold and italic but can still be opened by nearly every word processor past, present, and likely future.

Choosing A New PC Or Mac

question-computerA gig is a gig is a gig – 1,024 megabytes, sometimes rounded off as 1,000MB. So yes, hard drive sizes are consistent across Mac and PC hardware. Processing speeds are harder to compare. You can go digging across the Internet for all sorts of bench tests, but you’re better off comparing PCs to PCs and Apples to, well, Apples.

Typically a sub-$500 PC is not going to be worth the cost. In my experience they fail more quickly and catastrophically than more expensive models. A midline PC, in the $700-1,000 range, offers better and faster hardware. Laptops will be more expensive than desktops, and bear in mind that if you choose Windows 8, you’re going to want a screen with touchy-swipey capability for the best experience. That is, assuming you can find one; it’s not available for every model.

Macs may cost more, but in my experience they also make up for the price difference by outlasting their PC counterparts in the long run.

Troubleshooting Slow Web Sites

slowWaiting for web sites to load may be a function of your network connection and not your computer. Or, if your computer is gummed up with adware and malware, you’ll notice the drag particularly when using the Internet. For optimum speed you need to use a modern operating system – Windows 8, Mac, or Windows 7 as long as Microsoft deigns to support it – because you need to use a modern browser.

Your web browser is your window to the Internet. That means it’s also a vulnerable point. If your software is out of date, your connection will seem slow or you’ll be unable to load pages or images. The older the browser, the slower the connection, until you finally throw your hands in the air and buy a new computer. This is another reason it’s good to keep your software up to date, it’ll stave off that new computer moment as long as possible.

If you don’t know which browser you use, you’re probably using the default for your system. Common browsers as of this writing are as follows, but this information changes rapidly. Your best bet is to use the “check for updates” feature of the program to find the current version for your computer.

Windows 7 and 8

Mac

Note: there is no current Internet Explorer for Mac. If you’re still using the old versions, switch now!

Choosing A Mac Model

choose-appleThe easiest way to see the available Macs is to pop over to the Apple store: store.apple.com. They have a clickable list in the Mac section which shows the Mac model options.

In my experience, you are almost always better off opting for an iMac or a Macbook Pro than trying to cut corners with a Mac Mini. For one thing, you have to factor in the cost of the screen, and for another the Mini really doesn’t have the oomph for what most people want. You don’t have to go nuts on one of those bigger, expensive tower Macs. Those are usually purchased by designers and video experts who need the extra processing power and expandability.

When configuring a Mac using the Apple Store tool, get the fastest processor and best graphics you can for the model you want. You can always add more memory or a larger hard drive later, but with an iMac or Macbook you’re stuck with whatever processor and graphics card it has. You can go Macbook Air instead of Macbook Pro but remember you’re sacrificing processor speed for a lightweight form factor.

Apple Store has a nice comparison tool to help you make the choice.

Finding Discounts On Macs

I’d be remiss if I didn’t mention you can look for discounts on warrantied refurbished Macs on Apple’s site. You can also find discounts at Mac retailers like Mac Mall and OWC. A good time to buy is right after Apple announces new hardware; you can get a discount on older models that still have solid tech specs. (Insider’s tip: Apple usually has events in the spring and fall; the next one will be in March 2013.) If you’re an educator or student, be sure to check out Apple’s education discount. Many colleges and universities have deals through the campus computer store.

Ten Ways To Tell If Your Computer Is Infected With A Virus

Ever get that sinking feeling that something’s wrong with your computer? Here are ten ways to tell if your computer is infected with a virus.

Run a virus scan
A bit obvious, isn’t it? While you’re at it, make sure your antivirus program has been updated recently. If you haven’t bought a new version in a few years, now’s the time.

Run a second virus scan with a different program
Antivirus programs sometimes come up with different results. It’s a good idea to scan with a second program to pick up anything the first one left behind. However, you shouldn’t try to run two antivirus programs concurrently; they’ll conflict with each other. I like free programs Malwarebytes for PC and Sophos Antivirus for Mac.

Watch your computer’s behavior
Is it slower than usual, crashing, having a hard time redrawing the screen? These can all be signs that viruses are running in the background.

Monitor active programs
If a virus is running in the background, it may show up in the list of active programs. You can then click on it and End Task (Windows) or Force Quit (Mac). Bear in mind, though, most viruses will restart on reboot, and some will even regenerate on the spot no matter how many times you quit them.

  • Windows XP
    Ctrl-Alt-Delete, then click Task Manager
  • Windows Vista/7
    Ctrl-Shift-Esc
    or right-click the taskbar and click Start Task Manager
  • Mac OS X
    Option-Cmd-Escape (the Force Quit menu)
    or open a Terminal window and type ps -aef

Check your Web browser extensions
Browser extensions provide additional functionality on the Web. Some are terrific tools while others are sneaky little devils that serve you ads, slurp your data, and otherwise spy on you. Here’s how you can check your browser extensions.

Check your Sent folder
If your email is spewing spam, it may show up in your Sent Items folder. Viruses often commandeer email accounts to send spam.

Check your Facebook and Twitter
If there are all sorts of weird links on your Facebook wall that you didn’t post, your account may have been hijacked. And if that’s the case, it may have happened through a virus infection on your computer.

Start in Safe Mode
If your computer is so confused it won’t work properly, you can boot into Safe Mode which may allow you to diagnose the problem.

  • Windows XP, Vista, 7
    Hold down F8 at reboot (before the Windows logo)
  • Mac OS X
    Hold down Shift at reboot

Ask the Internet
Fortunately we don’t have to compute in a vacuum. If you think you’re infected with a particular virus, do a Web search on it. You’ll often find removal instructions and links to tools (just make sure those tools are legit and not themselves viruses in disguise).

Inspect your other computers
If one is infected, it’s likely the others are, too. You need to keep all your computers secure, even if they’re old or you don’t use them often.
