Version

To determine the installed version of clamav and associated frontends, issue the following.

> clamdscan --version
ClamAV 0.95

> klamav --version
Qt: 3.3.8b
KDE: 3.5.10 "release 21.9"

Manual Update

To manually update ClamAV, visit http://clamav.net and download clamav. Verify the signature or checksum, unpack the package, read UPGRADE and INSTALL, and then perform the following.

Step 1

Configure using a standard account. Since configure only requires reading source files and invoking tools, a standard account is adequate. Note that clamav default prefix is /usr/local, which is a different path than used by the OpenSuse rpm.

> cd clamav-0.95.1
> configure --prefix=/usr --disable-clamav

If you receive the error message, User clamav (and/or group clamav) doesn't exist, you most likely did not pass --disable-clamav to configure.

Step 2

Make using a standard account.

> make

Step 3

Acquire administrative privileges and then change directory into the package directory used to build clamav.

> su -
password:
cd clamav-0.95.1

Step 4

Install the new clamav.

# make install

Step 5

Return to a standard user account.

# exit
