IMHO, you don't need antivirus on a Linux box, unless you're going to run a mail relay, where you are responsible for saving recipents from viruses.

I agree. Check that your ISP performs virus checks.

Thanks guys, good points. The USB vector reminds me of stuxnet, although this I understand was designed to infect Iranian MSWindows boxen. Anyway, the use case in point is to protect other MSWindows OS' when sending/forwarding office and pdf documents. So the user would like to be able to scan emails as they come in/sent out.

This is not current, but if it is to be believed (and without details on the methodology I'd be reluctant to believe it) clamav came 2nd after Karspersky: http://www.builderau.com.au/blogs/byteclub/viewblogpost.htm?p=339270831 This on the other hand is both current and more meaningful, because it includes zero day attacks: http://www.shadowserver.org/wiki/pmwiki.php/AV/VirusDailyStats ClamAV on linux comes 3rd for zero day attacks and 16th on retries. -- Regards, Mick [-- Attachment #2: This is a digitally signed message part. --] [-- Type: application/pgp-signature, Size: 198 bytes --] ^ permalink raw reply [flat|nested] 37+ messages in thread

You don't need one. Linux anti-virus programs are there to protect Windows installations (Windows executables passing through a Linux box). Since you said "Desktop", I assume you meant protect against Linux viruses. Since there aren't any Linus viruses, there's no need for something like that. ^ permalink raw reply [flat|nested] 37+ messages in thread

Yet. There are literally *millions* of Windows viruses. The Wikipedia page just proves Linux has virtually no viruses, and those listed don't even work anymore (exploits have been patched long ago.) Most existing Linux malware targets servers (like PHP software exploits in forums, wikis, etc) and desktop users don't need to worry. Furthermore, even if there were enough Linux viruses to worry about, there isn't a good way of getting infected. On Windows, you download random executables from the net.

And most malware runs an exploit to install itself, it doesn't require the user to run an installation program. So typical attack vectors are: network services, documents/media files (.pdfs flash etc), and all the usual web stuff. As stated earlier buffer overflows against Gentoo would be a nightmare to write due to the system variability....RHEL not so much. ^ permalink raw reply [flat|nested] 37+ messages in thread

That still doesn't protect you against man-in-the-middle attacks or an attack against the CVS tree (like the recent kernel.org disaster).

I have to agree with most everyone else on this one. You don't really need a anit-virus software to protect yourself. I do think it is good that you want to protect others by catching them while on your machine and then you know not to spread them around to others who can be infected. I used to do this a long time ago but I have policies here about sending messages to others. Mostly, I don't do it unless I know it is virus free. If I get a video that is funny or something, I find it on youtube and just forward a link to that. I'm sure youtube checks its stuff to be sure it is clean. If you set up a process like this, you shouldn't spread anything but you do have to think before hitting forward too. I think people have figured out I don't forward just anything so I don't get a lot of "junk" anymore. I do agree on using AVG as someone else posted. I have that on my brothers XP box. He likes it better than Norton that he used to pay for. If you can get that running on Linux, then that would be great. Another pretty good one that I used to use was f-prot but I think AVG would be better still. Dale :-) :-) ^ permalink raw reply [flat|nested] 37+ messages in thread

I did check the WinXP fs for all the files and registry entries that this trojan is meant to create and none were present. Then I've zero'ed the pagefile and a second scan did not flag anything up. I also checked for a reported trojan in a Windows 7 vdi file (in virtualbox). Nothing found there either. I am tempted to think that avast! is rather super-sensitive. However, avast! also picked up some php files from a backed up website - so this may be a worthwhile find. Anyway, I can't make it integrate with kmail which was the original user requirement.

You don't really need a anit-virus software to protect yourself. I do think it is good that you want to protect others by catching them while on your machine and then you know not to spread them around to others who can be infected.
