Beware of
Attachments
Most viruses
aree 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 we’re here to
talk about today. If you’re 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 ploy to get you to open their email and activate the
virus which is always an attachment. Most Anti-virus nowadays stop, or
at least warn 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.
