It’s a jungle out there – be smart online

Recently, I posted a job on craigslist for a senior systems and network engineer.  Although craigslist is a popular site, I have never used it and had some concerns about posting on a site that has received so much bad press. After researching, I decided to post our job and have been very happy with the response. But it’s a jungle out there and I knew to expect some scam artists to use the ad to try an attack. Then today, I received an email from updates-craigslist: Updates!New Terms – Accept: June 29, 2011 with the following message: ———————————————————————- craigslist ———————————————————————- Dear Customer, We need your help resolving an issue with your account.

How to Protect Your Computer Against Malware

Each year the damages from computer malware cost US businesses billions of dollars. These costs are not only in lost productivity, but permanent loss of critical business data. Arguably, most if not all infections are preventable with the proper understanding, training and protection. Don’t be the next victim, take the steps now to ensure protection and recovery if the worst should happen. First, let’s understand computer malware. Often the term virus is used to describe all malware. Technically speaking, there are viruses, rootkits, Trojan horses, worms and spyware. The attack method may differ but they are all malicious. A virus is a program that runs itself and replicates itself. It can affect files or the boot sector and can delete all your data. The “Melissa” and “I Love You” viruses gained global attention. A rootkit or Trojan horse allows access to your system without … [Read more...]

Managing Rows and Columns in Excel

Guest author David H. Ringstrom, CPA,www.accountingadvisors.com Users often hide rows or columns in a spreadsheet to conceal private data, or perhaps just to keep a large spreadsheet manageable. This is a helpful feature in Excel, but many users often go about managing rows the hard way: Excel 2007 or later: In the Cells section of the Home tab choose Format, Hide & Hide, and then make a selection as to what to hide or unhide. Excel 2003 and earlier: Choose Row or Column and then Hide or Unhide, respectively. Hiding rows is fairly straight forward, as you can select the rows or columns, and then carry out the aforementioned menu command. To unhide rows or columns, you must select rows above and below the hidden section, or columns to the left and right of the hidden section, and then carry out the menu command. Constantly navigating the menus to hide and unhide rows or … [Read more...]

One-Third of World Spam

With the arrest of Oleg Nikolaenko, the young Russian responsible for billions of spam messages each day, the world is wondering what it would be like with one-third less spam. There are over 250 billion email messages sent each day. With 86,400 seconds in a day, that’s about 3 million email messages a second.  Conservatively, 80% is spam.  That means that 2.5 million emails each second are spam.  Many of those emails are caught by spam filters, but the spam that makes it to inboxes still cause major problems.  Spam is profitable and despite the repeated warnings, people still click on spam. Ordering pharmaceuticals or fake Rolex watches from spam hurts you in two ways. First, they take your money for the item and you get an empty box if you get anything at all.  And second, you can be highjacked and become part of the botnet.  A botnet is like the Borg for computers. Your computer … [Read more...]

Black Friday and Cyber Monday

This year just about every retailer is using the term Black Friday and Cyber Monday to advertise their special “specials” and grab the attention of holiday shoppers.  Those seem strange terms, not very glamorous or even illustrative of a bargain.  In fact, they sound more like viruses and cyborg attacks out of a sci-fi movie.  So why have they caught on? Used to describe sinister or catastrophic events occurring on a particular day of the week, Black Friday has been used for everything from massacres to meltdowns.  Today, we most often use the term for shopping the day after Thanksgiving.  Coined in the late 1960s by the Philadelphia police because of the choking traffic and crowds, the moniker caught on and by the mid-1970s was being widely used.  Later the term Black Friday was redefined to mean the day that retailers become profitable or put some black ink on the ledger. It is an … [Read more...]
