Hello i want to know, how to protect myself against FUD (fully undetected) Keyloggers/trojan/RAT’s.
Some people make a virus FUD to send it to someone, so that the antivirus doesn’t detect it as a virus.

How to protect myself against this kind of things?

I don’t know where you heard this FUD (Fear, Uncertainty, Deceit), nothing is fully undetectable.

Common Sense also plays a major part in your protection.

So someone sends you something, by email, you have to A) accept the email, B) open/Run the attachment or C) click on a link in the email taking you to a remote site or running a remote script, etc. So there are plenty of opportunities to smell a rat (excuse the terrible pun) and delete the email.

There would have to be a degree of complicity from the user.

So, never open unsolicited emails, don’t open attachments or click links in unsolicited emails.

Thank you David for your reply, i will follow what you we’re saying.

But some viruses are FUD (Fully Undectable)(Search yt for some video’s) That means it’s crypted so it bypass the antivirus/firewall etc…

So… how that works. how to protect against that.

Thanks again for reading

Like DavidR said there is nothing impossible to be detect, Hashs exist, even cryptic malware can be detected, and even malware packed is something like themida can be detected.

Are u sure? I have seen on youtube/forums some video’s about a FUD Crypter that Cryp the RAT/Keylogger. And if you want to send it to someone, it’s bypassing the antivirus

Soving i noticed you have another thread going on over at malwarebytes on the exact same issue, you also need to know that you shouldn’t have two av’s on your system at the same time because this can cause conflicts and lesson your security levels so you should choose either mse or avast, you’ve got avast and malwarebytes so if you want to add to your protection get the real time scanning of malwarebytes ( PRO ) and a good third party firewall, these are all free ( online armor, privatefirewall, outpost free suite with firewall only, comodo firewall )
You can also get the avast suite ( AIS ) which includes a firewall and combine that with malwarebytes.

Yeah that’s right, Ok so witch antivirus shud i use?

Avast (free)
MSE or
COMODO

Well being that you are asking this question in the avast forum i guess you should already know the answer, if you look at antivirus testing company results avast is always a top performer and doing better than some of the top paid av’s, my second choice would be MSE.

Did u ever tried COMODO antivirus:

http://antivirus.comodo.com/antivirus.php

Some people are using this and they advise it more than Avast (free) and mse.

A processor cannot execute encrypted instructions, it has to be decrypted at some point (and hence it’s detectable). Of course there are many many ways of making detection harder, but it’s never impossible.

Nope, no reason to try it as avast has better detections, better speed and better forum.

Off-topic: Then I advise you avast! more than Comodo :slight_smile:

YouTube is hardly the most reliable source of information … in fact a large proportion of the things found there are total cr*p.

Wow, if I didn’t know better I would have though I posted that as it mirrors my impression of facebook.
