I have installed a malware program on my Linux system
I have installed a virus protection program too...

I understand that malware is not the same as spyware... It is used to hide the movements of a hacker
So is there spyware for linux... or any programs to protect against it
for instance on windows there is spyware to get your personal information such as passwords to bank accouts online and other things... in windows there are spyware and adaware programs to help protect against this... Or do I not have to worry about it (ie doing online banking)
I am running kde desktop on a AMD64 Gentoo Linux
Thank you in advance for your help

Well...
Spyware itself isnt so prevalent on linux, as in order to install, it needs root priviledges. Tracking cookies and so on still work fine. Browser "extensions" arent a problem (yet), partly because the major focus for spyware/adware writers is still IE rather than Firefox/Opera. However, as Firefox gets more popular, you should expect to see more adware attempts for it.
The easiest means of getting spyware onto a linux box right now, is through a closed-source app, such as some of the firefox plugins, drivers and so on.

What exactly are you trying to protect from though?

There really aren't any linux spy-ware as far as I know of. I think the only thing that really could happen is using "unofficial" scripts. Other than that you should be ok.

Well basically, think of the possible ways spyware could be installed into linux.
In order to be installed, the spyware's installer needs root privilages.
Theres a few ways to get said privilages: Exploit a vulnerability in some software, or get the user to run the software as root.
The first issue is already around in linux. As linux gets more popular, you could expect to see some spyware try to install itself in a similar manner to a virus, by exploiting said hole. At present, most attacks on these holes are used to install backdoors, trojans and so on though.

Getting the user to run the software as root is a similar vein of problem. You either use a traditional trojan, hack some sourcecode etc....
Or you have a user running a browser as root, and get them to visit a page that can install software without user interaction ala IE.

Both of these require the some form of non-normal state of the computer. Either a bit of vulnerable software that runs SUID as root, or the user running as root during normal usage, which is NOT normal :P

Basically, it is a lot harder to actually get spyware on linux, as normal users cant install software globally.

The main thing that I ame trying to protect from is identity theft... People getting passwords to online banking etc... Because on windows it is a big problem with spyware and stealing information
It seems like linux is more secure and that isn't a problem (but you can never be sure)
Thanks for the info

If you store your passwords on the computer, youre asking for trouble.
You must at least store them in a file readable only by root, and also encrypt said file with a GOOD passphrase.

As far as keyloggers etc.. go, theyre already around for linux. For spyware to work on linux, it requires the same conditions as a trojan or virus. So, learn how they get onto systems, protect against that sorta thing, and you'd be fine.
