AntiVirus Options

Could do with some advice,

I have a full registered AV for my Dual Boot PC (working nicely thanks to previous advice here ) But my AV distribution only provides support for windows and Novell - no Linux distributions.

In order of confusion;

Is there a generally accepted best AV for linux? (Red hat in my case)

Are their any companys that ppl can recommend (I've seen lists of some that exist - but that doesn't mean they are good of course...) that allow 1 liscense to cover a dual boot pc running the AV in both linux/windows?

I have a simple freeware proggie for windows that executes and crc checks a variety of file types to check if they have been altered. Is their somthing similar under Linux?

Cheers for any help..

It was VERY weird for me to get away from the virus world in Windows. I figured, "Ok, how do i protect my lin box from a virii?" But alas, after much searching, i came up with the knowledge that there has 'never' (from my sources anyhow) been a functional or harmfull virus made for linux. The simple fact is that it's too hard and if you do get something made you MAY be able to make the system hicup once. In summation, you don't need one. I'd concentrate my efforts into a decent firewall which will assure your security 100x better than Windows ever could. You'll notice all of the 'security holes' in linux apps, well that's because "crackers" (no, not a white person lol, ok err) use holes to gain acces in linux as opposed to using virii which don't do diddly doo.

Take what taz said with a grain if salt. Viruses are made by someone for a very specific purpose. Sure, there aren't as many Linux users as there are Windows users, but both can be susceptible to virus attacks. The thing is, there aren't as many viruses made for Linux as there are for Windows only because most desktop users are on Windows.

If someone were to write a virus to cause devastation, they would attack the most used OS to have the greatest effect. If we lived in an alternate universe were Linux was the beast, people would be saying there are no viruses for Windows.

With that said, the majority of viruses out there are made for and only work on Windows. There are several Linux viruses out there and as Linux continues to gain popularity, more will be made by people with too much time. Just a quick search for "linux virus" on Symantec's site came up with a mere 39775 results. Certainly all of these matches are not viruses, but the first 5 I looked at certainly are.

Don't be fooled by people saying there are no viruses for Linux. Since a majority of viruses are tailor-made for the Windows environment, chances are even if you accidently download one via email or some other way, you won't be affected while using Linux. Try checking out or freshmeat for antivirus utilities for Linux.

Nice answer Beelzebub, I'll just tack on some output from Mcafee's uvscan:
Found the Linux/Exploit-Bind trojan !!!
Found trojan or variant Linux/Rpcmountd !!!
Found trojan or variant Linux/Exploit-Statdx !!!
Found the UNIX/Exploit-Crontab trojan !!!
Found the Linux/Adm.worm virus !!!
Found the Linux/Ramen.worm virus !!!
Found the Linux/Adm.worm virus !!!
Found the Linux/Exploit-Bind trojan !!!
Found the VBS/GMW.gen virus !!!
Found the BackDoor-AB.svr trojan !!!
Found the BackDoor-FI trojan !!!
Found the FreeBSD/RootKit trojan !!!
Found the JS/Bomb trojan !!!
Found the VBS/GMW.gen virus !!!
Found the BackDoor-FB.svr.gen trojan !!!
Found trojan or variant JS/Bomb !!!
While part of this is Wintendo crap, it's good to realize on Linux viruses aren't the main part to look for, but rootkits, exploits and worms and shit like that.
So I'd rather detect something like that and quarantaine it.
From a few tests (my malware stash, aprox 300 examples) I ran AV scanners tru I found Mcafee's uvscan and RAV giving the best hitrates.
Btw, the examples above are all "in the wild", it's not a FUD thing.

Fair comments, but the most important thing (especially for newbies) is the fact that viruses cannot > do < much whilst in a Linux environment.

I agree with Taz, firewalling is far more important in Linux.

Surely the only time it would be an issue would be if you're connecting to Windo$e boxes and 'everyone' knows they need AV software......

You can go for Kaspersky AV. It's very good, it works for in Windoze, Linux, .. i usually go to, but they have more sites. One good think about kav for linux is that they have a good av scanner for sendmail, which is the rare case.
If you clean your email of viruses than you have eliminated 99% of viruses.
