Electronic Document Management Systems and Spyware
Electronic document management systems are computer systems designed specifically for managing electronic documents such as text, excel sheets, PDF scans, etc. Larger companies have massive numbers of documents which need to be edited, sorted and stored. This is something that can never be done manually. Using a “paper and pencil” approach would require a large man power and lots of money.
There are different types of document management systems. Some of these are specialized computers that were designed exclusively for document management. However, modern document management systems are more of software type. Document imaging software are specialized software which run on ordinary Windows or Linux based computers.
There are several advantages of using document management systems. Some of these include:
-
Lower costs: Once the software license is purchased, the only over head costs include the power to run the systems. There is no paper or stationery involved and so the costs are minimal.
-
Speed and efficiency: Computer systems are much faster when compared to manual work. So, this is one bog advantage.
However, there are some factors that need to be taken into consideration which using document management systems:
-
Security: If the documents contain sensitive information such as credit card numbers, social security numbers or banking details, it is essential that security measures be taken. Since document management systems are servers connected to the Internet, a hacker could potentially make use of some software bug and get access to sensitive information. For this reason, it is essential to use a high quality Internet security suite.
-
Crashing and stability: If the computer on which the software system is running gets infected with spyware or malware, it could crash the system and lead to data losses. This can be prevented by using a high quality spyware solution and also by making regular back ups.

12 easy tips to make Windows boot up faster
Here are 12 easy tips to make your Windows computer boot up faster. This will apply to all ‘flavors’ of Windows i.e. Windows Xp, Vista and 7.
1) Remove unwanted applications from your start up: Use msconfig or some utility such as CCleaner.
2) Clean up your desktop: Unwanted clutter can slow boot up.
3) Defragment your disk: Very important if you have a large number of files on your hard disk after months of using your computer.
4) Check for malware: Viruses can eat CPU cycles and RAM and slow your computer down.
5) Update your BIOS: May not be necessary, but if new firmware has been released, there is no reason why you shouldn’t be updating.
6) Set the computer to boot from the Hard Disk in BIOS: This can save a few seconds.
7) Remove removable media & peripherals when booting: Can save another few seconds of time.
Disable unused ports: This can be done in the BIOS.
9) Remove fancy wallpapers, themes or sounds effects: This eat up plenty of RAM and CPU cycles. Use Windows Classic theme for best performance.
10) Upgrade Windows, apply patches and service packs: This should make your computer faster by fixing loopholes and make your OS more secure.
11) Hibernate your computer instead of shutting it down: May increase your power bills but worth the money as it saves plenty of time in the long run.
12) Clean you machine: Use a vaccuum cleaner or a blower to ensure that your computer is dust free.
How to Know if You Have Spyware on Your Computer
Do you think someone is spying on your internet activity? Though Norton or McAfee might be able to locate spyware, some may be so well-written as to escape detection. In any case, downloading more software willy-nilly in an attempt to protect your computer is more likely to make things worse. Here are some steps a Microsoft Windows user can take to detect spyware activity; Macintosh OS/X, Linux, and users of other operating systems will have similar but different methods available.
- Press Ctrl-Alt-Del (all 3 keys simultaneously, known as a “three-finger salute”). This should pop up the Task Manager, or whatever Microsoft is calling it lately. One of the tabs should be Processes; click that tab.
1) Look up every process name on the Internet. Don’t trust all the information that you find, but try to get a general consensus from the more reliable sites whether that process name is likely to be malevolent or not.
2) Even if a process name is normal and expected (like svchost.exe), it’s still possible that a “hacker” was able to overwrite the normal system process with a tainted one.
3) If a process looks suspicious, for example u-r-0wn3d.exe, you will need to attempt removal. See Tips for ideas on that process.
- Open a command window, also known as a “DOS box”, by clicking Start | Run | cmd, or Start | Run | command on older systems. Type in the command: netstat -an. This will show you a list of systems you have connected to, and systems connected to you, and all “listening” ports. Learn the port numbers: 80 and 443 are typical for the “web”; 135, 139, and 445 are for Microsoft networks; find out what they all mean. If you see something suspicious, netstat -anbv might show you what process is doing the communication.
