Pozbądz się przynajmniej na razie GG :stuck_out_tongue:

Zdaje się żę to nie robi nic szczególnego oprócz rozpowszechniania się.

I chyba oczywiste jest żę antywiry oparte na bazie sygnatur są bezurzyteczne jeśli chodzi o nowe wirusy, zwłaszcza takie o zasięgu lokalnym. Zdaje się że w tej chwili 2/20 antywirów rozpoznają to jako wirus.

Z drugiej strony antywiry oparte na heurystyce są :

a) wolne

b) znajdują wirusy tam gdzie ich nie ma

Możę to do pewnych osób nie dociera, ale naprawdę przynajmniej 1% dzieciaków uczeszcząjących do liceum w naszym kraju jest w stanie napisać trojana i bindera, np w delphi.

Z jednej strony takie coś nie będzie ię potrafiło samo rozpowszechniać, ani nię będzie potrafiło zrobić nic więcej niż np zresetować komputer czy pokazać jakieś okienko z głupią wiadomością. Jednocześnie żaden program antywirusowy nie zauważy że to zły program jest.

Nic dziwnego, że windziane Firewalle się zmieniły w takie kombajny. Bo mozliwość zabronienia programowi odpalenia innego exeka jest potrzebna w dzisiejszych czasach :stuck_out_tongue:
