ELFaGeek is almost right. Most Virus Protection "for Linux" -- is an oxymoron: it's for Windows, not Linux, and it's not protection and definitely doesn't help with viruses. ONLY Clamav is good virus protection for Posix-compliant systems like Linux or UNIX. When I started with Linux most of the bad stuff would be targeted towards your machine -- and I was neither obnoxious enough nor had good enough data to be targeted though I met both victims and perps. A FEW REAL black hats have targeted Linux lately but we still don't have enough resources to make it worth the hassle for most of them. With my background I'm paranoid period. So I run clamav. It's not ABSOLUTELY necessary, but it has never given me those messages on ANY system and it's the ONLY AV (as opposed to rootkit hunters) I will trust till I talk to professionals about some other package.



Your AV sounds like malware. Uninstall it if you can and reinstall Ubuntu if you have to. Just get rid of it.

Answer 2

You do NOT need any Virus Protection App on Linux, period. Did you use Apt Get to install this un-identified Virus App? If so, that's what you did wrong.



But, rather than drive yourself crazy trying to figure out how to un-install the FUBARed Virus App from Ubuntu:



Just re-install Ubuntu on the same partition that it's currently installed on. This will replace the FUBARed Ubuntu with a Factory-fresh installation, and the FUBARed Virus App will be gone forever.



TIP: The Installation Instructions are a free download from Ubuntu's website. And, next time please tell us the full name of App that is causing the Installation problem. And use the new Software Center App in Ubuntu.

Answer 3

Virus Protection...??? Linux??? You don't need that. In terminal the following code will force the removal

"sudo dpkg --remove -force --force-remove-reinstreq package name"



(without the quotes) and substitute package name for the package you tried to install. If that all goes well for you (hopefully it does), I would recommend while in terminal also to use the following: (no quotes)



"sudo apt-get update"



"sudo apt-get autoclean"



"sudo apt-get clean"



"sudo apt-get autoremove"



do each of these one at a time... this will clean up the trash in the apt cache if any dependancies had been tried to install and are not needed. Hope this helps get things staightened out for you... without having to do a fresh install.
