1.  A Refurbished Computer Problem

Subscriber Janet wrote me recently about her (mis)adventure buying a used computer on eBay:

Hi Terry, I've got a few problems I'm hoping you can help me with or at least tell me where to look. I just bought a newer computer off eBay.

Since I do a lot of research on the Internet I needed a computer that would support my having open 8-20 web pages at one time. After a good bit of reading I came the conclusion that what I needed that was within my low budget was a used computer with a higher speed processor than on my old computer (it had approx. 2100Mhz) and that I needed a lot more megs of ran (I only had 521) and that I needed dual processors or at very lest hyperthreading.

I could not find dual processor computer in my price range so I looked at hyperthreading computers. I finally found one that I was would fit my needs and in my price range. Last weekend end I bid on an eBay auction and won a Dell OptiPlex, with 2000 megs of ram, a 3000Mhz processor that did hyperthreading and it had a much larger HD. My old HP computer only had an 40Gig HD, but this Dell I bought has a 250Gig HD and a CD/DVD burner.

Here' the auction so that you know what I bought:
[link removed - Terry]

It arrived on Friday afternoon, 4-11-08, so I spent Saturday evening (last night) trying to see if it worked right. It powered up just fine. I used the CD Player to load my AOL software and that went fine. I also tested it with a CD that had been made here at home and the CD music player worked fine as did the speaker connections. I was able to get my broadband Internet connection set up and get on the net and go to Goggle and link to various web sites. I am able to see graphics and videos over the net. XP Pro seems to work OK, as little of it as I've used, I see no problems.

Now here is where my problems started. The 1st thing I noticed after a few hours after it was running was that it was making a high pitched sound. It was not loud and if you walked 5' away you would not hear it. Today when I started up the computer it made that sound intermittently and now it's gone. I did research that noise earlier on the net and found that with this GX280 Dell it could be the power supply or worse it could be bad capacitors on the mother board. Since it's quit the high pitched noise do you think it's OK or should I look at some other things to see if there is a problem and if yes, what should I look at?

The next thing was that decided to ck to be sure that the processor speed was the 3000Mhz. I went into my computer on the desktop, then to properties and then I became a little concerned because in properties, under general it says something different from what it say when I look up the system information from the start menu.

In properties says-- just like this: Intel(R) Pentium(R) 4 CPU 2.8Ghz 2.79Ghz, 1.99GB of Ram

In the devise manager it says: Intel(R)Pentium(R) 4 CPU 2.8Ghz

In system information, under system summary it says: Processor: x86 15 Model 4 Stepping GenuineInel(R) ~2793Mhz SMBIOS Version: 2.3

So I'm not sure if I received what I've paid for. I've spent hours looking on line and I still can't figure this out if I was shipped what I paid for. Would you give me your opinion? If you have the time I' really appreciate your input.

Once again, many thanks for reading my email and any help you can give me, Jannet in San Diego, California

Jannet has a couple of problems here. First and foremost, she purchased a computer that was listed as a 3.0 GHz Pentium 4 — but the one she received identities itself as a 2.8 GHz Pentium 4.

I suspect, though, that this was an innocent mistake by the seller, who is an eBay "Power Seller" with a lot of positive ratings from buyers. The seller has a number of similar 2.8 GHz refurbished Dell computters for sale as well as some 3.0 GHz models. I hope that a simple mistake resulted in the wrong unit being shipped to her. I hope that Jannet has contacted the seller and gotten the problem resolved to her satisfaction.

The other issue is the high-pitched noise she mentioned. There are a number of reasons a computer can make sounds that indicate problems. Some are serious and some turn out to be very minor.

Since the computer had just been shipped to her, I suspect that some wires in the computer had shaken into different positions. A fan could be making the sound as its fan blades hit wires. Been there, done that...

3.  My Computer Security Software Recommendations

Anti-Virus

I'm often asked about several other popular anti-virus or anti-virus combination packages. Yes, I realize that they are not in my recommendation list. "Enough said..."

My personal choice is the ESET's small, fast NOD32 anti-virus program, which offers a FREE 30-day evaluation license. I consider NOD32 to be the cream of the crop in anti-virus protection. Unlike some of the others, ESET offers multiple-year licenses also, including updates to the program in the multiple-year license.

Many antivirus programs will offer you an anti-virus signature subscription renewal when your subscription renews. I strongly recommend against this option — buy the full program or make sure you get program updates with the subscription renewal (like NOD32 does). Vendors routinely improve the capabilities and speed of the programs, too.

If you update only the signatures, you miss any program improvements. Fortunately, NOD32's subscriptions include both program updates and signature updates.

Firewall Software

While the Windows XP firewall is much better than no firewall at all, don't count on the Windows XP firewall to meet your needs. You need a two-way firewall, which the Windows XP firewall is not!. Microsoft woke up and supplied a two-way firewall with Windows Vista.

The Windows XP firewall does not control outbound communications originating from your computer — and you should want to have control if adware/trojans/spyware or even commercial products want to talk to the Internet. Whether they are calling home or spewing spam, you want to be able to control your computer.

Do you want Windows Media Player to call home every time you play something? It does! Do you use the Search function in Windows Explorer to find things on your hard drive? Did you know that every time you search, Windows Explorer talks to Microsoft?

I didn't know that when I ran ZoneAlarm, but the Sunbelt Personal Firewall flags that to me, and I can stop it or allow it to happen. Many other programs try to call home when you run them, too.

I recommend my choice for a firewall program, which is Sunbelt Personal Firewall.

You can try the full-featured "paid version" of Sunbelt Personal Firewall free for 30 days — after that, you can register it or, if you're using it on a home non-business computer, you can let it revert to the free, lesser-function license.

Sunbelt Personal Firewall is regularly $19.95 (with discounts for multiple computers and/or multiple years!) for a non-expiring license for the program and includes one year of their updates subscription.

Anti-Spyware / Anti-Adware Software

CounterSpy, from Sunbelt Software, has received many kudos from the computer press for its always-running and periodic full system scans. It is also my personal choice for my PC's and my family's PC's.

Sunbelt released their CounterSpy v2 in February 2007 and I promptly updated my computers to it. Version 2 greatly improved CounterSpy's performance and reduced its load on the computer when it was scanning.

In July, 2007, Sunbelt released v2.5 of CounterSpy, which again both improved CounterSpy's performance against malware and reduced its impact on system resources and responsiveness when its scanning.

Sunbelt continues to release updated program versions. Nicely, they do NOT install the updated programs automatically. You have to use the Update process in the program, which means that you'll know that something significant has changed!

Anti-spam Software

In today's Internet world, the question is not "if" you will get spam, but "how much will you get?"

I use and now I recommend POPFile as my first choice for handling spam. POPFile sits on your computer, between your email program and your ISP mailbox, and handles emial as it downloads.

POPFile uses a different approach to handle spam than some other programs do — it does nothing to reduce spam. It is designed as an email classification tool — you train it to recognize spam and any other type of email that you want to classify. These classifications can help you sort your emails into appropriate folders in your email program.

Sunbelt Software, who makes the anti-spyware program CounterSpy (which I use and recommend) and the firewall that I use and recommend (Sunbelt Personal Firewall) also has a well-regarded, award-winning anti-spam program called iHateSpam for Outlook and Outlook Express. Since I don't use Outlook or Outlook Express for email, I haven't tried iHateSpam.

Mailwasher Pro is my first choice to handle spam before it ever gets into your computer's Inbox. Mailwasher Pro uses on-line Realtime Black Lists mail servers sending spam recently, "training" by you of what you think is spam, and your own "friends" and "blacklist" lists.

Mailwasher Pro can even bounce spam messages, as if your email address was not valid, although the usefulness and appropriateness of this is questionable. There is a free version called "Mailwasher," but it omits the functions that I consider critical for this purpose -- such as safely previewing the emails safely before they ever get to your email inbox.

Cable/DSL Router

If you have a cable modem or a DSL modem, you need to have another layer of inexpensive protection between you and the Internet. A cable/DSL router isolates your computer from direct connection to the Internet. Your computer can easily request your email, web pages, etc. through the router. The responses come back to the router and are smoothly routed to your computer. But, someone on the Internet side of the router can not initiate a connection to your computer — they can only respond to your request.

Even if you only have one computer to connect to your cable or DSL modem, I recommend that you purchase and use a cable/DSL router because of the protection it can give you against attempts to attack through some flaws in Windows itself.

A router isolates your local network, whether it is only one computer or several, from the Internet by actually making it a separate network. The router gets the "public" IP address and handles all your outbound communications and the responses to them. But, it blocks computers on the Internet side from being able to initiate communications with your computer! This will prevent you from falling prey to many worms that try to attack security holes in Windows itself.

For a wireless router, I recommend the Linksys WRT54G wireless router. I'm using the relatively new version 6 of this router.

If you don't want wireless, I recommend the Linksys BEFSR41 wired router. Either way, based on my experience, I recommend Linksys routers for price, reliability and Linksys' habit of releasing updated firmware for their products..
