Antivirus for Linux, Installation Issues-please help!?

Filed under class registration system
Our class is installing antivirus for Linux, Fedora Core 3 on 2 clients and a server. I can download and install Avast-Home Edition (Free), but when I try to run it, the only way it will work is by scanning ONLY the home directory, standard scan. If I try to scan the entire system and/or do a thorough scan, the system freezes. It will lock up the entire computer and not recognize the keyboard or mouse so the only way to shutdown is to hold the power button. Every time I reboot, Avast makes me re-insert the registration key before allowing me access to the scanner. I have already uninstalled all previous versions/downloads of antivirus as well. Please help!
I appreciate the sentiment, but this is for SCHOOL and I must use Linux, and yes, there are many viruses and hackers for Unix/Linux as well so antivirus, firewalls, etc are definitely needed so please don’t post Windows spam promotions as an answer…

i dont think u even need an anti virus for ur linux, but anyway…..
If u want to scan all files, even those apart from the ~/ then u need to login as root.
U could either login as root or login as a normal user, open a shell, and type:
su
once u r in super user mode, run the av from the same shell.
It will be able to scan all files.
logging in as root is usually not advisable, but if its just a personal computer, go ahead, its quite easier.
all the best
Krypt is correct as you have 2 options and both will require that you have the root password for the machine. You probably do as you would have needed it to install Avast in the first place.
1. Login as root and run avast
2. Login as a normal user -> open up a terminal -> type “su -” and enter the root password. run avast from the terminal.
Note that Krypt asked to run “su” as oppose to “su -” in step 2.
“su -” will give you root’s environment (path) and “su” will not.
If your computer freezes again do the following:
Hold down:
CTRL + ALT + F1
This will take you to a terminal. Login from there as your user or root and run the following command:
“ps -u yourusername | less” <- insert your user name where it says “yourusername”
hit the “down” arrow until you find the avast process and its process id (first set of digits)
then run the following command “kill -9 processid” <- insert the process id where it says “processid”
this should have terminated the avast process.
Now you can hit the following keys to return to the GUI:
CTRL + Alt + F7
Your session should no longer be frozen.
Good luck!
