One of the computers in our household obtained a drive-by virus infection recently. This particular infection is one of the famous backdoor Trojans that arrive by exploiting browser security from a web site that would otherwise seem harmless. The web site in question already was infected by the server SQL Injection exploit, which was replacing the web pages with ones that framed the content and contained malware JavaScript.
The computer in question was running Windows XP service pack 2, in a non-administrative account, with a 20-day old Symantec Antivirus 7.x virus list.
Why would anyone bother? In this case, the software that was loaded had all sorts of powers. It was malware, spy ware, and blackmail ware all in a blended threat. One piece attempts to open a back door to your computer, so that it can be controlled in a botnet. A botnet can be used to send internet traffic such as denial of service attacks, spam emails, and deliver other content. Another malware program brings in other software that shows up and attempts to blackmail you into buying it so that your computer will continue to work.

Using Microsoft SQL Server 2000. You may see this strange type of error. This is the OLE DB error reported from an ASP.NET web page
Quote:
The OLE DB provider 'SQLOLEDB' reported a schema version for table '"{your table here}"' that changed between compilation and execution. OLE DB error trace [Non-interface error: Schema version number changed from compile time ({number}) to run time ({new number}) for ProviderName='SQLOLEDB' TableName='"{your table here}"'.].

Now that visual Studio 2008 has been released, there is yet another Microsoft .NET framework version 3.5. This builds upon the 3.0 version released earlier, so both parts are installed in separate directories. There are a couple of articles in the Group29.com forums talking about .NET framework and Visual Studio issues, these are consolidated in this article.

This tech tip from the Group29 Tech forums has a large number of hits so it has been bumped to its own article.
Help, I just received an e-mail from an associate with a file I need, but I get the message: "Outlook blocked access to the following potentially unsafe attachments"!
This happens when you are using Outlook XP (2002) or Outlook 2003 and someone sends you a VBS, EXE, CHM, MDB, BAT, or other Level 1 security risk file. (See below for more). Now while a real hassle, there really is no reason someone should send you an exe in an email. So remember that this is a precautionary measure.

Here is the scenario, I was using a gridview
control in visual studio 2005. I had an itemtemplate with a label for
the value and an edititemtemplate with a dropdownlist to use to select
values. Unfortunately, the actual row in the main table did not have a
corresponding entry in the source table for the drop down list. So I
got an error:
System.ArgumentOutOfRangeException: DropDownList1 has a SelectedValue
which is invalid because it does not exist in the list of items.

| When the Adelphia deal was finally inked after their corporate scandal and subsequent bankruptcy, Comcast and Time Warner acquired and split up the cable assets. I became a Comcast customer who had their Time Warner franchise taken over as part of the divestiture agreement between both companies. I expected very little problem with my cable TV, as I only subscribe to basic cable. The cable companies currently provide very little to those with HD TV unless you pay an exorbitant fee. I did expect major changes with my internet service, as my e-mail addresses were changing from rr.com (Roadrunner) to Comcast.net.

Help! Someone is using my Credit card number! (Credit Card Fraud Help) |

Identity Theft and credit card fraud are a hot topics these days. A resourceful
thief can pose as you using your name and credit card number and spend all
sorts of money without your knowledge.
Several credit cards I have possessed in the last 20 years
have been used by someone other than me. It has happened with two Discover
cards, two Visa cards, a Master card, and an American Express card.Fortunately, as a consumer you are well protected. In fact,
the retailer really is the one who is ripped off. Not only is a retailer hit
for 2 to 3 percent of the sale by the credit card company, but they also end up
paying when the credit card company disputes any charges. If the charges are
disputed and the merchandise is gone, there is nothing left but a police report
to be filed. As the consumer you do not have to file a police report, because
in the end you will be OK. Here is what to do in case you suspect fraudulent
activity on your credit card.

If you are the tech support guru in your social group, you may have heard this cry: Help! I have a virus and I am going to
reformat my C: drive!
This is usually followed by: All virus writers should be drawn and quartered! (or similar gruesome punishment.)
Do not despair! Before you go off the deep end, we need to find out just exactly what the problem is. You may not be totally dead.
Viruses do many different things these days. Mostly they want to gain control
of your computer and replicate themselves. Past viruses tended to infect
executables, usually rendering the computer inoperable. Someday, we might see a
prolific time-bomb virus. But to be successful, a virus must at least replicate
itself. If you can stop the intruding program from running, you can usually
clear up the problem.
