Different Types of Computer Viruses





There are Different Types of Computer Viruses could be classified in (origin, techniques, types of files they infect, where they hide, the kind of damage they cause, the type of operating system or platform they attack) etc. Let us have a look at them...


Computer Virus is a kind of malicious software written intentionally to enter a computer without the user's permission or knowledge, with an ability to replicate itself, thus continuing to spread. Some viruses do little but replicate others can cause severe harm or adversely effect program and performance of the system. A virus should never be assumed harmless and left on a system. Most common types of viruses are mentioned below:



Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.



Direct Action Viruses
The main purpose of this virus is to replicate and take action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.

Overwrite Viruses
Virus of this kind is characterized by the fact that it deletes the information contained in the files that it infects, rendering them partially or totally useless once they have been infected.

The only way to clean a file infected by an overwrite virus is to delete the file completely, thus losing the original content.



Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.

The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.



Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.



Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.

Once infected it becomes impossible to locate the original files.

Polymorphic Virus
Polymorphic viruses encrypt or encode themselves in a different way (using different algorithms and encryption keys) every time they infect a system.

This makes it impossible for anti-viruses to find them using string or signature searches (because they are different in each encryption) and also enables them to create a large number of copies of themselves.



File Infectors
This type of virus infects programs or executable files (files with an .EXE or .COM extension). When one of these programs is run, directly or indirectly, the virus is activated, producing the damaging effects it is programmed to carry out. The majority of existing viruses belong to this category, and can be classified depending on the actions that they carry out.

Companion Viruses
Companion viruses can be considered file infector viruses like resident or direct action types. They are known as companion viruses because once they get into the system they "accompany" the other files that already exist. In other words, in order to carry out their infection routines, companion viruses can wait in memory until a program is run (resident viruses) or act immediately by making copies of themselves (direct action viruses).



FAT Virus
The file allocation table or FAT is the part of a disk used to connect information and is a vital part of the normal functioning of the computer.
This type of virus attack can be especially dangerous, by preventing access to certain sections of the disk where important files are stored. Damage caused can result in information losses from individual files or even entire directories.

Worms
A worm is a program very similar to a virus; it has the ability to self-replicate, and can lead to negative effects on your system and most importantly they are detected and eliminated by antiviruses.



Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.

Logic Bombs
They are not considered viruses because they do not replicate. They are not even programs in their own right but rather camouflaged segments of other programs.

Their objective is to destroy data on the computer once certain conditions have been met. Logic bombs go undetected until launched, and the results can be destructive.

How to increase signal of your globe tattoo

from diegobayo of http://www.symbianize.com/showthread.php?t=157497

Tools needed:
-extension wire (manipis lang)
-screw driver
-syempre globe tattoo kit
_________________________________________

eto po yung previous signal ko.




sa signal meter ko is FULL BAR ang GPRS.

kaya nag isip ako ng way para tumaas ang signal to WCDMA to HSDPA, lumabas ako ng bahay kasama ang laptop,
napansin ko na nagbago ang signal from GPRS to WCDMA,
kaya 100% sure ako na magiging HSDPA ang signal ko
kung mailalabas ko ang Globe Tattoo modem ko.

Lets Start na po.

Steps by steps procedure

-buksan natin ang Globe tattoo modem
look na lang sa mga attached image




alisin muna ang sim para madaling buksan


tapos dahan dahang buksan sa gilid yung modem.
ingat lang baka masira ang casing ha.






ito na yung RF signal receiver ng globe tattoo.
all we need is to extend xa kasi nga nakadikit sa kit.

try to remove yung screw ng RF receiver.



dito tayo mag lalagay ng extension wire. look sa image



nag ipit na lang ako ng extension wire sa screw kasi ayaw ko i mount yung wire sa modem kit baka masira dahil nga plastic lang ito.



pag naikabit nyo na yung extension wire, ibalik na natin sa dati ang tattoo kit
kayona bahal maghanap ng butas na lalabasan ng extension wire ha
wag nyo kalimutan ang mga screw na tinanggalnyo ha,
wag iwala dahil mahirap humanap non.







dito ako ang lagay ng butas para sa extension wire ko.





yan.....tapos na tayo.



Oras na para masubukan kung uubra na.....

eto po ang picture after malagyan ng extension wire.

[TUT] How To Double Firefox Speed

Firefox is in my opinion the best browser ever made until now. It includes:
-improved tabbed browsing
-pop up blocking
-integrated Goggle search
-enhanced privacy controls
-built-in phishing protection
-online spell checking
-lots of themes, interfaces, and extensions/addons

Mozilla Firefox officially supports:
-Microsoft Windows
-Linux
-Mac OS X

Unofficial Support:
-Free BSD
-OS/2
-Solaris
-SkyOS
-BeOS
-XP Professional x64 Edition

Now here are some Tips&Tricks that can help you double the speed of Firefox.

1. Type about:config in the address bar and then press Enter.

2. In the filter search bar type network.http.pipelining. Be sure the value field is set true,if not double-click to set true. HTTP is the application-layer protocol that most web pages are transferred with. In HTTP 1.1, multiple requests can be sent before any responses are received. This is known as pipelining. Pipelining reduces page loading times, but not all servers support it.

3. Go back to the filter search bar and type network.http.pipelining.maxrequests. Double-click this option and set its value to 8.

4. In the filter search bar and type network.http.proxy.pipelining. Once opened doubleclick on it and set it to true.

5. In IPv6-capable DNS servers, an IPv4 address may be returned when an IPv6 address is requested. It is possible for Mozilla to recover from this misinformation, but a significant delay is introduced.
Type network.dns.disableIPv6 in the filter search bar and set this option to true by double clicking on it.

6. CONTENT INTERRUPT PARSING
This preference controls if the application will interrupt parsing a page to respond to UI events. It does not exist by default. Right-click (Apple users ctrl-click) anywhere in the about:config window, select New and then Boolean from the pop-up menu. Then:
A. Enter content.interrupt.parsing in the New boolean value pop-up window and click OK
B. When prompted to choose the value for the new boolean, select true and click OK.

7. Rather than wait until a page has completely downloaded to display it to the user, Mozilla applications will regularly render what has been received to that point. This option controls the maximum amount of time the application will be unresponsive while rendering pages. Right-click (Apple users ctrl-click) anywhere in the about:config window, select New and then Integer from the pop-up menu.
A. Enter content.max.tokenizing.time in the New integer value pop-up window and click OK
B. You will be prompted to enter a value. Enter 2250000 and click OK.

8. CONTENT NOTIFY INTERVAL
This option sets the minimum amount of time to wait between reflows. Right-click (Apple users ctrl-click) anywhere in the about:config window, select New and then Integer from the pop-up menu.
A. Type content.notify.interval in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 750000 and click OK.

9. CONTENT NOTIFY ONTIMER
A. This option sets if to reflow pages at an interval any higher than that specified by content.notify.interval. Right-click (Apple users ctrl-click) anywhere in the about:config window and select New and then Boolean from the pop-up menu.
B. Type content.notify.ontimer in the New boolean value pop-up window and click OK.
C. You will be prompted to choose the value for the new boolean. Select true and click OK.

10. Notify Backoffcount
This option controls the maximum number of times the content will do timer-based reflows. After this number has been reached, the page will only reflow once it is finished downloading. Right-click (Apple users ctrl-click) anywhere in the about:config window and select New and then Integer from the pop-up menu.
A. Enter content.notify.backoffcount in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 5 and click OK.

11. CONTENT SWITCH THRESHOLD
You can interact with a loading page when content.interrupt.parsing is set to true. When a page is loading, the application has two modes: a high frequency interrupt mode and a low frequency interrupt mode. The first one interrupts the parser more frequently to allow for greater UI responsiveness during page load.
The low frequency interrupt mode interrupts the parser less frequently to allow for quicker page load. The application enters high frequency interrupt mode when you move the mouse or type on the keyboard and switch back to low frequency mode when you had no activity for a certain amount of time. This preference controls that amount of time. Right-click (Apple users ctrl-click) anywhere in the about:config window and select New and then Integer from the pop-up menu.
A. Enter content.switch.threshold in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 750000 and click OK.

12. NGLAYOUT INITIALPAINT DELAY
Mozilla applications render web pages incrementally, they display what's been received
of a page before the entire page has been downloaded. Since the start of a web page
normally doesn't have much useful information to display, Mozilla applications will wait
a short interval before first rendering a page. This preference controls that interval. Rightclick (Apple users ctrl-click) anywhere in the about:config window and select New and then Integer from the pop-up menu.
A. Enter nglayout.initialpaint.delay in the New integer value pop-up window and click OK.
B. You will be prompted to enter a value. Enter 0 and click OK.
