Actually there aren’t so many options available in choosing right antivirus software(in comparison to other applications) on Ubuntu 9.10 or 10.04 because Linux based operating system is not vulnerable to the most of the viruses and *wares(Due to the Fact that,Some years ago,only windows XP or other windows NT based operating system were suitable for common users so crackers and virus programmers had busy in creating viruses for windows OS. Another reason is that Linux based operating systems are much secure than windows).
But know things has changed and now Ubuntu 10.04 Lucid Lynx is becoming popular among common desktop users(for Home use as well as professional purposes due to the benefits of Open Source tools). That’s why It is a good idea to use antivirus tools in Ubuntu 10.04.Some Common and most recommended antivirus software for Ubuntu 10.04 is ClamAV and Avast.
Update!
Anyway, I don’t prefer to use any antivirus softwares on Ubuntu Linux based operating systems such as Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 (Lucid Lynx) or Linux Mint or Fedora… If you really want to secure yourself from cyber threats then first secure yourself on the Internet. Here are some good recommendation for a beginner :
- Use strong passwords (Learn how to make strong passwords)
- Always type url in the browser e.g http://www.amazon.com
- check https (secure padlock) in the address bar before entering any confidential information on any website
- Use Logout for closing a session
