Eset Smart Security can't detect some viruses!!!!!!!!!

i m 1month user of Eset smart security

but i have problem about this antivirus

when i insert my pen drive into usb then eset cannot detect automatically any viruses but when i open this pen drive then eset detect then
but the main problem is when i open pen drive then the virus automatically enter into the system file location
also when i scan my pc at this time the virus is detected !!!!!!!!!!!!
so should i do?

so this is not a realtime protection for file becoz if any file corrupted so u can't recove it so my main suggestion is that

IMPROVE THE SELF-DEFENCE MODULE & AUTOSCAN FOR REAL TIME VIRUS DETECTION & REMOVING

when this module are fixes then their is no challenge for Eset Smart Security!!!!!!!!!!!

 

what virus is being detected?

 

Self defense is a useless marketing gimmick, if a threat got past to have the chance to disable the AV, the AV failed. Having self-defense won't fix anything apart from the fact the AV will still be enabled with a threat on your system.

 

Actually this thing also happen with other av product even kaspersky n avast pro edition(i use before) also same only detect when i open it...It u wan to solve tis why dun u try USB Disk Security.It automaticly scan when u plug in your pendrive...
