HAVE YOU EVER SUFFERED FROM PC CRASH, DATA LOSS, SLOW OPERATION, AND SO ON?

If your answer is yes, then virus is one of the others to be considered causing such problems.

Be careful with opening e-mail attachment. It may contain virus, but it does not mean that you can never open it, just to make sure it is sent from your real sender. If you see some unexpected attached file, be sure to check with your sender before opening it or scan it first. Here are some of the more common file types which may hide viruses:

.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.
