Email Attachments
In Email attachments, we should always be careful. If we see the file extensions look like these below, take a extra precaution.
.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)
File extensions tell what the program is and 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. Hackers use some emails and activate the virus, which is always an attachment. Most Anti-virus nowadays stops, or at least warns you of high risk attachments. But don’t just rely on that. Don’t open a file or any link from a sender that you don’t recognize to be doubly sure.
