[Quick Question] Is it possible this can happen?

Hello, just would like to ask a quick question:

Can a password stealing Trojan or keyboard logger Trojan which is unknown to our ANTI-VIRUS software even with the latest virus database able to break into our systems and have my password or CC# stolen?


THANKS!!!! plsssss... very important for me!

Hi ttk_2k, welcome to Wilders.

That is the key word, and the answer is of course, however, if the antivirus in question has good heuristics like NOD32 does, then there is a good chance it will be detected generically.

Cheers

 

Thanks for your message Blackspear!

I asked this because yesterday I used NOD32 to scan my PC, it reported everything was fine, but later Kaspersky 6(trial) found out a Trojan Downloader, I didn't delete the infected file immediately, but used NOD32 for taking a new scan again, still it couldn't find it. Then I updated the virus database of NOD32, it soonly found the virus.

So I'm doubting how secure your PC would be EVEN have an anti-virus software installed and EVEN with the a so called latest virus database. Those new trojans can come into your system and for example a key logger, etc..

The main thing I want to know through this question, is that if these anti-virus or firewall softwares could detect activities of an UNKNOWN virus? For example, when a trojan which is unknown to our antivirus softwares is logging our keyboard inputs, maybe its moving like entering somewhere via certain port of our pc, or sending the logged file to the far end, could somehow be detected by our anti-virus software or firewalls, couldn't they? I mean otherwise a firewall or a antivirus software can change their types to known-fire-wall, or anti-know-virus software... LOL

Sorry for my poor english, wish you could get what I want to tell.

 

I understand what you are saying, you are doing really well.

A combination of NOD32, a good Firewall with outbound protection and a HIPS program like Online Armor will set your system up like a fortress, there won't be much that can get past this.

Hope this helps...

Cheers

 

Hi, thank you Blackspear for you fast reply, it really helps!

So with that combination, even an unknown trojan will not be that easy to steal our information or log our keyboard, right?

Thanks once more!

 

Indeed, really hard to get past that combination.

My pleasure.

Cheers

 

Do you EVER sleep BS? You posted at 2pm GMT. Go to bed!

 

I think you must add 10 hs to his time.
UTC/GMT +10:00

 

It may not have been as dangerous as it sounds. Although extremely annoying, it might have been nothing more than an adware downloader/installer (often flagged as "Trojan-Downloader.Win32...." by Kaspersky), or one of those that download and install rogue/fake antispyware/antivirus programs.

 

This was detected by NOD32 later , but anyway , ESET are soon going to have a Suit which will include a firewall in it which means that the firewall and the heuristics will make NOD32 users really unbeatable guys .

 

LOL, my time, it was 11:11pm, I usually head off between 11:30pm and 12:30am
