Uthenga womwe kachilomboka kakutumiza uli ndi fayilo yowonongeka yomwe imawoneka ngati chithunzi cha JPEG. Fayilo yoyipayi idawononga makompyuta ambiri a Mac ndipo apa ndipamene Leap-A idadziwika.
slammer
Chabwino, uwu ndi mtundu wa kachilombo kamene timawona nthawi zambiri m'mafilimu okhudzana ndi zamakono. Chabwino, kachilomboka ndi chitsanzo chabwino cha "kukana ntchito".

Ngakhale simuli katswiri wa makompyuta, mukhoza kudziteteza ku mavairasi ndi mphutsi zisanafike pa chipangizo chanu. Nawa malangizo omwe mungatsatire:
- Khalani ndi antivayirasi yaposachedwa yoyika ndikusanthula kompyuta yanu
- Osatsegula maimelo ochokera kunja, ndipo musatsegule maulalo a sipamu.
- Lolani Windows kuti isinthe, ndipo Zosintha zambiri za Windows zimabweretsa zosintha zina zachitetezo zomwe zimatha kukonza zolakwika pa PC yanu
- Osatsitsa mapulogalamu kuchokera kuzinthu zosadalirika.
