I'm using the Possible Unwanted Applications set to remove some of the junk that students store on our school's server... Joke programs, etc. Working well. What I'd love to see is emulators (nintendo, etc) added to this. I have spent a little time trying to learn how I might do this myself, but I can't really find the info. It would also likely benefit most people using this feature anyway... -- TimBates - 30 Oct 2008

I would like an additional category in Possible Unwanted Applications for demonstration software / shareware. This could be used to detect time limited or feature limited demonstration software, or software where a fee is payable for its continued use. -- MarkHobley 26th April 2009

When creating a new binary-incompatible libclamav.so.#, could you please also have the makefile build a stub library with the old .so.# which calls the latest one? (Or add a symlink if that would work?) Otherwise, I keep needing to recompile code before I can update ClamAV, which I'd rather do later as an optimization.

Thanks for a great product! -- MikeDonovan - 02 May 2008

Could the latest STABLE release of clamav please be saved as clamav-latest.tgz or something similar. Or at least linked to the above filename. This would enable me to run an automatic update script to install the latest release once freshclam detects that the current one is out of date. I have about 20 servers running clamav and it makes life very difficult to manually update the releases.

Any help with the above will be appreciated.

Regards Evan. -- EvanBooyens - 30 Jan 2007

Use

host -t txt current.cvd.clamav.net | sed -e 's/"//g' |cut -d ' ' -f 3|cut -d : -f 1
 or host -t txt current.cvd.clamav.net | sed -e 's/"//g' |cut -d ' ' -f 4|cut -d : -f 1

-- LG

More efficient is:

host -t txt current.cvd.clamav.net | cut -d \" -f 2 | cut -d : -f 1

-- McDutchie - 21 Oct 2007 audio/libvorbis *Oversized Zip option*
While it is possible to overcome the FOUND message by altering the ArchiveMaxCompressionRatio, it would be a huge benefit to me if there was an option to flag Oversized.Zip as WARNING rather than as FOUND such that copy, move and remove left these alone. The main objection to altering the compression ratio is that it increases the scan time. Furthermore, if nothing bad has been found by the time the standard settings have been reached, there is little likelihood that a deeper scan is going to find anything wrong. And, as it is, I am excluding these, so if there IS any problem, I'll never see it! At least with a WARNING, I've been put on notice.
