I feel they can. Some of the Hardware keyloggers use TEMPEST to detect keystrokes. This is the MOST Advance method, and very few methods to prevent it. But I guess, If so desperate until use TEMPEST, , Don't bother, much easier. Cheers!

TEMPEST is a codename referring to investigations and studies of compromising emanations (CE). Compromising emanations are defined as unintentionial intelligence-bearing signals which, if intercepted and analyzed, disclose the national security information transmitted, received, handled or otherwise processed by any information-processing equipment.

So, Privacy is no longer private. (=.=) Bad news, isn't it? Cheers...

Last but not least, keylogs are nasty and irritant. Once infected very hard to remove.

are u sure about this??
how about if using anti keylogger??
i think all av can detect threat that made by key logger,
but the av must update always...

(=.=) I disagree. Keyloggers can be removed, but for some cases, it is DAMN hard. Imagine having the keylogger working together with a Rootkit. Your computer is really condemned for a very long removal process...

Not every AV can remove Keyloggers. Some are practically useless. Cheers!

I don't personally think so.
Obviously you haven't use *undetected* keyloggers, I mean undetected.
There are private coded stuffs which hell lots of AV can't detect during release until users report that particular file.
Wait a min, who you're disagreeing with? Just to make sure.

thanks a lot for your info..
that news for me..
so u can give example of name key logger that can't detect by av&anti key logger??
just to know..

To name a few:

• Perfect keylogger pro edition - recoded and re-edited for customer
  
• *underground* submissions such as elitec0ders keylogger, which is quite stealth and injects into explorer.exe
  

*Forgot to close tag

have u try ardamax keylogger??
it is can detect or not?
sometimes santi psyware also can detect the key logger files and heal it???
it is true??

The so called "Invisibility" is COMMON features in Malware (Spyware/Adware/Malicious Code/Trojan Horses etc) itself.

The Invisibility against Process Viewers. This aspect needs to be tested. Most of the time, It is purely Thread injection OR API Hooking. Cheers!

Who I am disagreeing with? LOL. scorps, not eXPeri3nc3. HAHA.

In fact, injecting into Explorer.EXE is not that hard to detect . Use SREng. It will show every thread in every Running Program (PID). Cheers!

hahahha..
i know becoz i'm still newbie



how about that picture??

i don't get what u said above,
explain more..
please,

Some can hide their PID don't forget
Stealth, decides to stay in root and hides itself from detection, uses injection and rootkit to hide it's PID.

but sometimes  key logger also good for monitoring our kids that surf internet,
we will know what they do when surf internet,
and if we see in the keylogger viewer that they go to porn sites,
then we can give them a warning..

but when i scan with avg av, it still can detect and heal it??
how to make it invisible to all av??
hhehehehe

Many AVs use signature to detect malware. If the Keylogger is NOT Blacklisted by the particular AV company (As your case, AVG [You ought to change, it is not that good anymore. my opinion. Cheers!]), You CAN"T detect it. I am not sure about NOD32, as it uses heuristics instead. Cheers!

As the above.
