I started using Ubuntu 9.10. 
Do I really need to use an Anti-Virus?
And can you suggest some security softwares?
Yes, imoā¦ It isnāt attacked that much, but if only one bad thing gets troughā¦
Sorry, canāt advice a good av for linux, others are more into itā¦
Anyone ???
No.
No.
In two and a half years of using Linux, Iāve never even seen a Linux virus.
My advice is based on that fact. Bobās comment seems to be based onā¦ personal animosity.
So, as usual, up yours Bob.
For the really interestedā¦ ;D

happy readingā¦!

avast for Linux. Download and install the .deb package.
Bob, for anyone knowing something about Linux , it is obvious that Frank is right ;D soā¦
exactly, NO, and NO.
The only person suffering from a personal animosity problem seem to be you. 
My answer still stands.
Chris, itās your system and your security. You are the one who has to make the decision.
Well, againā¦ not quite true. ;D
So, as nobody likes the long versions, aboveā¦

And even if the virus will not effect your OS, you have thisā¦so you can recive and forward virus if not stopped in your computer
Cross-platform viruses
A new area of concern identified in 2007 is that of cross-platform viruses, driven by the popularity of cross-platform applications. This was brought to the forefront of malware awareness by the distribution of an Openoffice.org virus called Bad Bunny.
Stuart Smith of Symantec wrote the following:
āWhat makes this virus worth mentioning is that it illustrates how easily scripting platforms, extensibility, plug-ins, ActiveX, etc, can be abused. All too often, this is forgotten in the pursuit to match features with another vendorā¦ [T]he ability for malware to survive in a cross-platform, cross-application environment has particular relevance as more and more malware is pushed out via Web sites. How long until someone uses something like this to drop a JavaScript infector on a Web server, regardless of platform?ā[6]
Thanx Pondus, at least someone reads my linksā¦

In December 2009 a malicious waterfall screensaver was discovered that contained a script that used the infected Linux PC in denial-of-service attacks.[7]
I remember the story.
What do you think is the chance that any of the AV companies would have detected this malicious script for the few hours it remained on the download site? Iād say nil.
What is the advantage in having an installed AV (which is probably on demand only) if you can send a suspicious file to VirusTotal and have it checked by all of the AV engines?
Symantec want to take your money? What a surprise!
Symantec want to take your money? What a surprise!hmmm...maybe......and some use time, money and brainpower to make free antivirus for Linux ?
I donāt deny the fact thereās a possibility for malware downloaded in Linux (that wonāt affect anything on Ext3/4 anyway) to infect an NTFS partition, or an USB key that will in turn infect Windows if you dual-boot. But Iāve used Linux long enough and never saw it happen, so thatās one thing. The other thing is Iāve been posting during years on a few Linux forums (PCLOS, Mandrivaā¦a bit on *buntuā¦) and never saw anything reported about cross platform infections. First, many Linux users use just Linux, so thereās no risk as 99,99% of malware needs a Windows based operating system to be effective, while many others dual-boot (like myself, though not currently), and never got a virus infection from running Linux āunprotectedā. So, I just wonāt use an AV in Linux. If Linux went mainstream (could always happen, in years, another topicā¦), then chances are it will be targeted, and chances are there will be appropriate software - not the ones we have now that are meant for Windows files and processes (even if āusableā but useless in Linux like Avast for Linux) - but Linux security software, new software. One last thing, I read there were about 45 acknowledged threats for Linuxā¦not worth bothering 
+ itās sounds more difficult to run an executable with elevated privilege in Linux than it is in Windows (even with UAC on and a limited account).
Most are actually intended as money making exercises- aimed at the server market. The free desktop versions are just a spin off.
Iāve been using Ubuntu for two years. From what I understand, you do not need an AV for Ubuntu. Ubuntu is considered one of the more secure Linux distros. You run in an account with low permissions which makes it pretty secure out of the box. The only reason Iāve seen to use an AV is so you donāt help spread malware to your friends on Windows boxes. I think clam-tk is in the repos, a GUI for ClamAV that you could scan every so often if you are really worried about it. As long as you stay with official repos and repos that are well trusted, you are pretty safe from malware.

do you also surf on web sites that are in the repos ??? ;D ā¦OK the issue discussed here is potential online threats for Linux, and thereās almost none to say the truth. When I said about 50 in one of my posts above, that meant 50 all together, since Linux exists, so no big dealā¦ Linux security comes from Linux itself >>> move along, software companies, thereās nothing to see ā¦ at least not yet.
Hmā¦av for Ubuntu if you want then you can install the avast for linux or else you can surf carefree!
What I canāt understand about ubuntu when it plays a flash file with mozilla/google chrome is that it lag that why I prefer windows xp more
