File Extensions that you should be aware of

Nowadays, malware cases are increasing in numbers. We can't stop these crooks but we can avoid them. We should be careful with Email attachments and downloading some software from the net. Take note of the following extensions that might harm your computer:
.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)

These file extensions tell you what kind of programs. Most Anti-virus nowadays stops, or at least warns you of high risk attachments. But don't depend too much on anti-virus. You just have to be careful and alert at all times.
