Panda Antivirus for Linux is an antivirus for Linux servers and desktops. The project is an antivirus designed to be managed from the command line or console. To do this, an executable called PAVCL will be used.

The aim of Panda Antivirus for Linux is to scan and disinfect Windows and DOS workstations connected to a Linux server, as well as the Linux server itself.

Panda Antivirus for Linux scans files using both string searches and heuristic methods. The target files of the antivirus are Word documents, Java Applets, ActiveX controls and compressed files (ZIP, RAR, etc.).

At the moment, it does not scan the boot sector or the partitions table.

Panda Antivirus for Linux is a freeware version: Panda Software does not offer technical support for this software.

Antivirus Scan with F-Prot is a simple servicemenu for konqueror that allows to scan single or multiple files and folders using the F-Prot Antivirus. Antivirus Scan with F-Prot shows the result of the scanning in a textbox using kdialog. It can also show the progress of the scanning in a terminal.
I hope you may find it useful.
Comments or/and translations are welcome.
TO INSTALL: extract the content of the tarball and copy the file f-prot_virus_scan.desktop into ~/.kde/share/apps/konqueror/servicemenus (just for your user) or in /usr/share/apps/konqueror/servicemenus, /opt/kde/share/apps/konqueror/servicemenus... etc, depending on your distro, to make it system-wide.
This is only the service-menu, you need to have F-Prot antivirus installed on your system.

Yet Another antiVirus Recipe is a procmail that helps to filter out a lot of the most common e-mail worms.
For some of the above (plain iframe, clsid, xml, macro) e-mail is delivered normally but gets a WARNING in subject plus its old subject ($SUB).
Some of the warnings are:
WARNING-XML-CODEBASE-OBJECT-$SUB
WARNING-CLSID-EXTENSION-$SUB
WARNING-IFRAME-$SUB
WARNING-MACRO-$SUB
WARNING-NSCAM-SCORE:$NKNGS-$SUB
Main features:
- :: base64 signatures ::
- Most of these worms are MS-Windows executables and arrive at our e-mail encoded through base64 routines. YAVR uses especially selected signatures to locate these attachments. After that it places them in a directory (/virus/) sorted by name.
-
- :: iframe html exploit ::
- Through IFrame tag a html encoded e-mail can download and execute a file from a remote http site without informing the user.
-
- :: CLSID hidden extensions exploit ::
- Attachments which end with a Class ID (CLSID) file extension do not show the actual file extension saved and viewed with Windows Explorer. This allows dangerous file types to look as though they are actually innocent files, such as JPG or WAV files.
-
- :: xml codebase exploit ::
- Usage of some xml objects allow local files to be automatically executed, regardless of the security settings on the target machine.
-
- :: generic executable trap for bat, pif, vbs, vba, scr, lnk, com, exe ::
- The rest of MS-executable files that are not caught from base64 signatures end up in a virus-could-be file.
-
- :: generic macro detection for doc,dot,xls,xla files ::
- MS-Word and MS-Excel files that contain macro commands are marked with a warning.
-
- :: generic detection for most of nigeria scam e-mails (most of them) ::
- Nigeria scam e-mail is not a virus but a big spam problem... There are many good filters that use great algorithms for spam. This is just an add-on.
Enhancements:
- new switches for quarantine or not certain e-mailsbased on some ideas by Dan Smart
- YAVRQUARANTEXE if set to ON it sends unknown executables to /virus/virus-could-be as usual if set to OFF it delivers at inbox with a warning (and the X- header ;)
- YAVRQUARANTNIG same for nigeria scam
- YAVRQUARANTPRN same for porn e-mail read instuctions inside nkvir-rc
- X- marks in headers to help your own procmail scripts
- X-YAVR: MS-EXEC (any MS executable that wasnt identified by signatures)
- X-YAVR: NIGERIA (nigeria scam)
- X-YAVR: PORN (porn related)
- X-YAVR: MACRO (containing macro code)
- X-YAVR: XML-CODEBASE
- X-YAVR: IFRAME
- X-YAVR: CLSID-EXTENSION
- X-YAVR: SENDMAIL-EXPLOIT
- some more Worm.Moodown.b aka Netsky.b signatures
- another Mimail.Q

Kapitalist project is a Monopoly-like board game for 2-8 players. Walk around the board, buy properties, receive rent from your competitors, try to get monopolies to build houses and hotels on them and finally be the richest on the board.

avpmilter is a sendmail milter interface to the Kaspersky antivirus daemon.
Avpmilter gets virus scan result and tells sendmail MTA to send reject message upon virus detection. This program is not MTA, nor antivirus by itself.

In comparison with will Kasperskys kavkeeper it will improve performance of your mail subsystem because:
It will not reinject each message for each recipient back to sendmail MTA ( if sendmail receives, for example, one message for 30 recipients, kavkeeper will initiate 30 requests to antivirus daemon and 30 additional executions of sendmail program. Avpmilter will send only one request to antivirus daemon and will not initiate additional executions of sendmail program).

Avpmilter is small resident miltithreaded program, thus it avoids expensive fork() calls.
Avpmilter almost does not affects your current sendmail configuration. Moreover milter interface allows to run sendmail MTA and filter on different computers. avpmilter requires sendmail 8.11.x or 8.12.x built with milter support (which is the default option for sendmail 8.12). You can read about how to build and configure sendmail with milter interface in libmilter/README in sendmail source tree. Also you can find a good milter api ocumentation in libmilter/docs directory in version 8.12 of sendmail.

Scum of the Universe is a space trading game that combines two genres: arcade and strategy. On one side, its a classic vertical-scrolling space shooter game. On the other side, it is an adventure and strategy. You should choose whether youll be an independent space trader, firearms smuggler, fierce freedom-fighter or something in between.

Following the main storyline, you go through the galaxy from one planet to another. Space travel requires fuel, so you need to keep earning money to buy it. You can also buy various upgrades for your spaceship and weapons that affect the arcade part of the game. The storyline itself is not linear. There are also some points where youll need to make decisions that will determine your destiny.

For thousands of years, people of planet Xen have colonized the planets in their galaxy. As time went by, many colonies grew unhappy about their status, as everything was controlled by Xen. Some of them organized military units and declared independence. You can see the status of each planet by "Rebel Sentiment" indicator. Planets with RS higher than 50% are ruled by the Rebel government, and Rebel laws apply.

Trading firearms is legal on planets ruled by Rebels, as they need as much firepower as they can get. On the other hand, Empire forbid all the trading with firearms and other ground weaponry as they wish to maintain their military advantage. One of the ways to make a lot of money is to buy cheap guns at Empire planets and sell them for a lot of money on Rebel planets where demand is extremely high. But be careful as youll need to fight Empire fleet once they find out youre a smuggler.

Beside the raging war between Xen Empire and the rebels there is increased activity of alien species, who destroy human ships. The stronger alien activity, the more waves of alien ships youll need to defeat in each planets outer orbit. Some of the aliens you destroy may drop artifacts (big blue ones) which you can sell at any space station for 20credits a piece.
