Spyware checking?

[turbine]

What are some of the programs that we can use to check for viruses and spyware on knoppix? I've got a 3.3 hdd installation.

Thats not something you have to worry about on linux for the most part, viruses are almost nonexistant, spyware is made for windows machines, now if your looking to scan a windows hardrive for such, then I can't help you.

THere is a spyware/trojan for Linux and exist in a form of 'Root kits". And the only application I can found to eliminate this kind of attack is using 'chkrootkit'. You can read more from : http://www.chkrootkit.org/
You can download the program using apt-get install chkrootkit.

For antivirus, there is plenty out there. I use two antivirus in my system:
1) Clamav (it has daemon that runs in background)
2) F-prot (for scanning purposes only)

Why I use two antivirus? Because F-prot has gui (xfprot) but don't scan in background. ClamAV also has gui (klamav-still in alpha stage), but I seem cannot compile it. The only gui I manage to install is klamaktion which integrates into kde (but i don't consider this as a real gui rather than a script).

You can apt for clamav and f-prot. You may also want to apt for clamav-freshclam (clamav updater) and clamav-daemon.

Chkrootkit might give you false positives on LKM trojan with 2.6.x kernel. BTW, doesn't Knoppix come with chkrootkit installed?
I prefer rkhunter which you can install with:

wget -c http://downloads.rootkit.nl/rkhunter-1.1.5.tar.gz
tar -xvzf rkhunter-1.1.5.tar.gz
cd rkhunter
./installer.sh

You're right. Chrootkit indeed gives a false positive on LKM trojan.

This is true if you are using the liveCD, not a hdinstall, since you're running a ro fs!

Just to ring in, if you have a Windows install, I find the following to be excellent "free-ware"...

Spy-ware:
Spybot - Search and Destroy
--- Works great to rip out those ad-ware and spy-ware junk - it also can search in your registry for links to stuff too... ( those Internet Explorer Menu-Bars are excellent removals with this )

Anti-Virus:
AVast - you can get the "trial" version, and it does almost everything, even though it starts yelling about buying it - to get even more functionality - it still runs good, has Internet, mail, background scanning, and a scheduler - and all free-ware...

Before I "moved" to Linux, had these two in my arsenal - still do, on my backup "old" system, running Win98...
