A few days ago, one of my friend's colleague open an attachment file with .com extension inside an email, and the PC became infected with some kind of virus...
So, I wrote her a letter informing her some of the "popular" type of dangerous
file extension that could point out a Virus / Worm / Trojan possibility within.
The list is as follow:
.bat , .
vbs , .
exe , .
pif , .
scr , .com
.
dll , .reg , .vb , .
js , .cpl , .
cmdI might not be 100% correct. ( Please correct any mistake by leaving a comment ,
TQ )
But I would rather be careful then be sorry!
Oh, if any of you have any to add to this list, please leave a comment too! After all, they are ever evolving! Scary isn't it!
So, the next time you ever need to open an email attachment, please look at its
file extension closely. If it contains any of the above-mention extension, chances are it might be a Virus / Trojan file, especially if it from someone you don't know.
Even if you know the sender, it doesn't mean it's 100% safe! WHY? Because today Virus/Worm/Trojan once infected your PC, it can scan your whole hard drive for email addresses which it can then use to send out infected emails with one of YOUR friend name as sender, without he/she even knowing it!
Oh, one last thing, always make sure you update your
antivirus definition & its scan engine before receiving your mail! Good Luck, pal!
