There be Spyware here, Captain!
There be Spyware here, Captain!
The ships bell had just sounded the dogwatch as Captain Skag began to check his email. He had just began to read his favorite E-zine, “Pirates gone wild” when his first mate burst into the cabin. “Captain, a dark ship approaches!” He cried. The captain, after running up on deck, examined the ship with his spyglass. “Shiver me hard drives” he bellowed as he saw the lay of her jib. “Shes a wardriver! ” (Note of historical Interest, a Wardriver is a term used to describe a way of searching for unsecure wireless networks.) “They be after plundering information on the ships server! Quick me mateys, prepare to repel boarders.” The crew scrambled to turn their laptops off while the Captain rushed to turn the wireless router off. Up on deck, the crew watched as the dark ship faded into the night. The Captain had no sooner settled back at his computer when again the cabin door burst open, this time it was the cook. “Blimey Captain, all my recipes files are gone!” This was bad news because the cooks famous secret recipe for chile con carne was highly sought after since winning 1st place at the Pirates ball last year. Thank the Kraken we have our backups” the Captain growled. The cook, cursing, left. Well, back to my email the captain thought. He pushed the send/receive button on his email client. “Blow me down” he bellowed, (Pirate Captains bellow a lot) “Whats all this SPAM mail doing in my inbox?” This was getting as back as a case of scurvy. As he sat, his rage boiling, he became aware of a lot of yelling coming from the crews quarters. “Now what” he cursed as he made his way forward. Upon entering the crew area he was assailed by a thunderous din of curses. (Pirates curse a lot) The Spainiard was yelling he couldn’t get his new game, “Pirates Revenge ” to load. The Italian couldn’t get into his stock portfolio. (Yes pirates have retirement plans too). The others were drowned out by the first mate yelling about his Blog being Hacked. As he surveyed the carnage, the captain noticed one of the crewman sitting calmly, using his laptop with apparently no problems. Bellowing loudly for quiet, he asked the crewman who he now remembered came from the land of Unix, why he was not upset. He looked up, and said “Why Captain, I’ve got a AntiVirus program along with good AntiSpyware and a reliable Firewall. I’m protected from brute force attacks, Phishing emails and drive by downloads.” He went on to say that it looked like the ships server was accessed through the wireless router, which was not secured with WEP (wired/wireless equivalent privacy). “Arrrgg”, he bellowed, the IT dogs back at the Island hideaway had told him all was peachy with the network when they sailed to pilage and plunder. The crewman whose name was Billy said he could get things ship shape by giving the other crewman the CD’s of his AntiSpyware, AntiVirus and his 3rd party Firewall…. for a price! “Aye,” the Captain replied wit a feeling of dread, “Whats your price?” Soon all onboard were back online and secure. Billy had his pockets stuffed with pieces of eight and of course, was wearing the Captains hat, looking mighty pleased with his bargaining skills. The Captain headed back to his cabin, worried that mutiny may be afoot. He had heard Billy telling the crew about those cursed Macs! The lesson learned here was obvious; You need to secure your network. AntiVirus and AntiSpyware is a must, So is a reliable Firewall. Anything less, you might as well be walking the plank, Matey!

Computer Viruses: The Nasty Truth
The term, ?virus?, in computer technology, refers to a self replicating application that spreads by making copies of itself by inserting into other programs, other executables or documents, and when executed begins to perform harmful actions on the system. All computer viruses are deliberately created, not always malicious and some of them may be benign and simply annoying. Non-Memory Resident and Memory Resident Viruses: Non-Memory resident viruses, when they are executed, immediately look for other hosts that can be infected. When they infect these targets, they transfer control to the application program they infected. A non-resident virus has a finder module and a replication module. The finder module, once it finds a new file to infect, calls upon the replication module to infect that file. Memory-Resident virus stays in the memory and do not look for hosts to infect when they are executed. It stays active in the background after its host program is terminated, and infects files as soon as they are opened or accessed by other programs or the operating system. It does have the replication module like the non-memory resident virus, but without the finder module. Types of Computer Viruses: File Viruses: These types of viruses are the most common, and mostly infect open files and program libraries on an operating system. The virus functions by inserting itself into a host file, modifies it in such a way that the virus is executed when the file is opened. They are also known as left viruses. Today, there are known viruses infecting all kinds of executables of standard DOS: batch command files (BAT), loadable drivers (SYS, including special purpose files IO.SYS and MS- DOS.SYS) and binary executables (EXE, COM). There are also viruses targeting executables of other operating systems - Windows 3.x, Windows95/NT, OS/2, Macintosh, Unix, including the VxD drivers of Windows 3.x and Windows95. Macro viruses: Macros are used in most word processing programs such as Microsoft Office in order to automate or simplify recurring tasks in documents. Macro viruses are those viruses that use the application’s own macro programming language to distribute themselves, in which an unwanted sequence of actions is performed automatically when the application is started or something else triggers it. These macro viruses may inflict damage to the document or to other computer software but are relatively harmless, and are often spread as an e-mail virus. Boot Viruses: These were one of the most common viruses prevalent during the early and mid 1990s, when the use of diskettes was popular. These viruses infect or substitute their own code for either the DOS boot sector or the Master Boot Record (MBR), which controls the boot sequence of the PC. The MBR is executed every time a computer is booted so the virus will also be loaded into memory on every startup and spreads to every disk that the system reads. They are typically very difficult to remove, and most antivirus programs cannot clean the MBR while Windows is running. So, bootable antivirus disks are needed to fix boot sector viruses. Script viruses: They are a division of file viruses, written in a variety of script languages such as VBS, JavaScript, BAT, PHP, HTML etc. They can form a part of multi-component viruses or infect other scripts such as Windows or Linux command and service files. If the file format, such as HTML, allows the execution of scripts, they can infect it.
