Since I started using Avast Home Edition 4.5 (not so long ago) I’ve sent many malware such as adware, trojandownloader and other that are not detected by Avast to its virus lab. All those malware are not downloaded form VX sites (yes, at least it’s circulating in the real world) but they tried to hit my machine while I did my normal operation such as surfing, downloading software from the internet and the last one I sent (if I rememer correct) is W32/Delf-IV. But almost of them are not included in Avast VPS by now and hope all will add in monthly trojan VPS as always.

I think ALWIL reserves its resources to detecting only real-world threats and the most damaging threats according to this thread.

And if you can remember when MS04-028 JPEG Exploit are found, Avast is one of the last AVs that detect it and maybe Avast forced by users to do that.

But I think it’s not good in marketing scene when compare to other AVs such as Kaspersky because the average users like me not even know what is real-threats, what is viruses, what is spyware like, what is trojan like but I don’t want it and want my antivirus detects/stops it, if it fails it should be blamed.

The whitepaper called “Why Less is More in Virus Protection” written by Joe Wells (the founder of The WildList Organization International) may or may not true. :slight_smile:
