IT Forum / Picture password....
« on: March 30, 2014, 01:41:53 AM »

Picture password is a feature introduced with Windows 8 that allows you to create three different gestures on any image of your choice and use those gestures as your password. The gesture can be any combination of circles, straight lines, and taps. For example if the picture you chose was of a face your picture password could be a tap on each eye and then a circle around the mouth.

How do I enable a Windows 8 picture password?

1. Open the Windows Charms.
2. Click Settings and then More PC settings
3. In the PC settings window click Users and then select Create a picture password..

IT Forum / Be Careful with Attachments
« on: January 31, 2011, 12:20:59 AM »
There have been a number of really bad viruses just within the past 6 months. We've seen the W32.Beagle, W32.Netsky, MyDoom, and so on. Most of these viruses were transported or replicated from pc to pc-using email attachments. These are easy to spot if you're paying attention, simply because they are usually executable files, but not always.

Some attachments contain Macros (simple programs that run within other programs, all the titles in Microsoft Office use macros). If you're not that familiar with spotting file extensions, don't worry, that's what I'm here to talk about today. If you are a little hazy on the whole "file extension" thing then let's spend a few moments explaining it.

File extensions are what tell the program how to treat a particular piece of data. For example, most people are somewhat familiar with .doc or a .txt file extensions these are both text documents and when the user opens this file the Operating System looks at this extension and then knows how to open it.

Hackers try to use some sort of eye-grabbing ploy to get you to open their email and activate the virus, which is always an attachment. Most Anti-virus nowadays stops, or at least warns, you of these high risk attachments and even take measures to protect you. However, on the average 10-15 new viruses are created every day and I personally wouldn't count on any program to 100% protect my pc. That's why I scrutinize any email, if I wasn't expecting an attachment, I won't open it until I had a chance to talk to the sender.

Some of the more common file types used to hide viruses include:

.scr - Windows Screen Saver - USE CAUTION if you receive a screen saver via email. They can contain worms or viruses
.pif - DO NOT OPEN! This is most likely a virus. Clicking it will run a program or code that can mess up your computer.
.exe - executable file - a program that contains a virus, Trojan horse, or worm
.pps - MS PowerPoint (can contain macro virus)
.zip - Zip (compressed) file
.vbs - Visual Basic script
.bat - Executable MS-DOS batch file
.com - DOS executable command
.asp - active server page - internet script
.doc - Word document (can contain macro virus)
.xls - Excel file (can contain macro virus)

This is in no way a complete list. Just because an attachment may have one of these extensions doesn't mean that it is a virus, but it should send up warning flags. Hackers use clever subject lines, and viruses can appear to come from a friend so keep on your toes and don't fall victim to their deceptive traps. Scan those attachments and verify with the sender before opening.

IT Forum / Why has my browser homepage changed?
« on: January 31, 2011, 12:20:18 AM »
If when you start your browser it loads a different web site instead of your normal homepage, it is possible a malicious program has hijacked your browser and set a different homepage.

To change it back, click on the Tools menu then Internet Options. On the General tab, under the section Home page you should see an Address box. Type in the address of the site you want (or click Use Current for the site you are currently viewing) and click OK.
