Final (FBI) Warning

News, Warnings | Posted by Dennis July 6th, 2012

The DomainChanger (AKA DNS Changer) virus that I warned you about will “expire” this weekend.  I’m getting lots of phone calls about the hubub, so I wanted to give some explaination.  First of all, THE VIRUS IS IMPOTENT thanks to the FBI.  They shut down the crooks that set it up, and replaced the bad server computers with some of their own (ours… the taxpayers).  But if you ARE infected, the servers will be shut down soon.  What’s that mean?  You won’t get internet access on the infected PC.  You’ll have to remove the bug before you can surf.  Here’s a link to the site that will clean it up for you.  Interestingly, the daily “new IP’s” (or new computer addresses) to the FBI servers is still quite high: 300,000+ as of about a month ago.  That tells me there’s still a BUNCH of folks out there that are infected.  If you have friends or family whose internet suddenly stops working this weekend, this is probably why.

Searchable PDF’s

Helpful Hints | Posted by Dennis April 26th, 2012

“What is a Searchable PDF?”, my customers often ask.  Well, there are basically two ways to scan a document; 1) As a picture.  These can be saved as JPG, BMP, or any other picture format.  BUT they can also be saved as a flat, or picture-style PDF document.  You’ve probably run across these if you’ve ever had a PDF where you COULD NOT select text.  To get around this you need 2) to scan the WORDS within the document.  This is called OCR, or Optical Character Recognition.  The computer tries to interpret every little symbol as a letter or number, and then indexes those words for you, making it SEARCHABLE.  Note that you can often OCR to a Word document or other editor and then spellcheck, edit, etc.  You may need this because the accuracy of the OCR depends on the software and quality of scanned document.  A lot of scanners now offer these options.  OR if you own Adobe Acrobat (rather than just the Reader) it will OCR as well.  Here’s an article that steps you through it (thanks CreativeTechs!).
