Trojan

[TRshady]

I have zonealarm with everything in "high", norton anti-virus, updated and scan week and use spy bot everyday but for some reason they ALL let a trojan in and never spotted it, here it is:

RegKey : SYSTEM\CurrentControlSet\Services\PSEXESVC

"PSEXESVC.exe" is the process so check task manager.

I managed to spot it by using an ad-aware scan. even trojan remover never spotted it, and I thought I was safe .................

this has happened to me before with one of those "corporate" type trojans. the ones people use to spy on each other. did you find out where this trojan came from?

If you pack a trojan differently then its undetected.



For example, download sub7, dont use their packer, download some packer and package it, theres your undetected virus

soo :-/



Windows kind of sucks because there are millions / billions? of viruses for it, linux theres about 4 viruses that work for it or something

First @ all I can say when you use your firewall correctly no Remote Control Trojan (or any other trojan that need internetconnection) can send or get data. So it can be active, but cannot harm you much.

And Acecool your information isn't really correct. Anti Virus Tools in hour time use Heuristic searches so even a packed trojan will be detected cause of it's structure.

still takes up resources.

Also then why isnt this trojan detected?



Why arent GAME exes shown as a trojan? They access the internet, they send info back and fourth between a master server.

lol


um



There are probably 1000s, if not millions of undetected viruses/worms/trojans whatever
They are slowly found, they get detected if/when somone sends the virus to the av makers so they can update definitions or if they get it some other way.

it all depends

my firewall do not use any ressources from my desktop PC cause i got an old Pentium I 166 MHZ, 64 MB Ram 2 GB HD for some €uros and set up a Router/Firewall.

Then roessources needed by a desktop firewall aren't that much...
And it is not from interest if the trojan is known or unknown. A good configured firewall blocks ALL traffic. IN/OUT and the user can choose wether to allow or to deny programs to connect.
And when you allow a trojan to connect in and out then it's your fault!
