[Trisquel-users] malware

[chris . arijs]

Hi all,
Is there any possibility to check of the trisquel-os on a desktop is infected  
with a virus, or malware, or other stuff.
On Win-d ows there are plenty of Antivirus programs and mostly you can "see"  
that the system is infected.
Are there indications for infections of Gnu/linux trisquel ?
PS this is just a hypothetical question; My trisqueldistribution is not  
infected ( i think ! )
