Computer Virus Source Codes

TS ask q lng kung ano ang gamit nito....
 
salamat dito bossing pwede ko na i infect pc ng school namin ! JOKE lang !:thumbsup: :thumbsup:
:dance: :dance: :dance: :csa: :csa:
 
bka meron dn kyo un s runouce.exe virus hehehe kulit e d ko makita un source nun
 
(nibasa ko un mga comments)

ahaha, madaming evil d2 ah...

Well my opinion is this thread is nice, indi lang nmn for destruction use ang mga files na to gaya nung ibang comments na nega... It also gives an understanding about some behaviors ng bawat virus or malware na nagagawa...

sa katunayan dito nagsisimula ang mga developers ng much powerful na AV's
(naicp ko din yun gusto kong gumawa ng AV balang araw :D)

pero panu mu magagawa ang AV kung di nmn natin alam ang signatures ng viruses diba...
"bookmarked muna to at may thesis pa qng aasikasuhin..."

parang hacker lang na ang gusto ay mutual relationship sa i hahack nyang system...
(blue hat ata ang tawag dun)

well that's only my opinion... :p
 
ayos!.... :thumbsup:
NOTE: Use this only for educational purposes!.... Wag sa mga kalakohan!.... ^_^

Kua- pag kinopy ko ba to-d mgkkvirus??
 
wla pu bang sample kung anung file type isesave ang mga virus na ito??? tnx pu author...:clap:
 
@sixxs7 = vbs script ang mga yan kaya kung gusto mo eh icopy mo yung code dun s VBS script writer kung meron k nang ganun, wag mo lang icompile sa sarili mong computer kc ikaw din kawa2 pag naicompile mo sa computer mo tyak magka2problema ka.
 
AMA gumawa ng I LOVE YOU VIRUS...

AMA din ako aral ngayun..


gawa nga ako ng bago na virus..

ung my COUNTDOWN...tapos bigla lalabas HALIMAW sa screen..

thaen mag shut down na...


ehehehe[/QUOTE]

HAHAHAH ayos pre ah halimaw tapos yung nsa harap ng pc magkakaroon ng sungay hahahahahah.
 
this is a good thread. maganda kasi malaman ang source code para alam mo kung paano e counter. this only works on computers with weak anti viruses. iloveyou virus earn its respect in its time (hats off). pero dun sa may balak gumawa ng virus, mag isip kayo ng ibang paraaan kung paano ma bypass ang mga antivirus.

lumolobo ang virus definition dahil sa kagagawa nyo ng bagong virus. hahaha...
 
Salamat po d2 Mga Sir! curious kasi ako sa structure ng coding ng mga yan e, para gus2 ko mapag-aralan gumawa ng anti-virus para ma block yung mga ganyan eh.:thumbsup:
