What is a virus extension?
2009
We’ve received many e-Mails and requests for a list of virus extensions. In case you do not know what an extension is, it is the period + last 3 numbers of a file. Here are some extensions you should be cautious opening:
“.exe” (Executable)
“.scr” (Screen Saver)
“.com” (Not the website, but the file-type)
“.bat” (System file)
“.sct” (Script File)
“.ocx” (ActiveX Objects)
“.dll” (Dynamic Link Libraries)
Extensions that you should not be particularly afraid of:
Pictures such as: JPG, PNG, BMP, GIF, TIFF, THUMB, PIC.
Documents such as: DOC, TXT, EX, RTF.
Movies Such as: MPG, MPG4, MPEG, AVI, FLV, WMV.
I still recommend using an Anti-virus program to scan the ones you don’t particularly have to care about (in-case somebody releases a malicious virus via a private exploit found in those extension types). Check here for a list of anti-virus programs and firewalls.
