Fayrasyadu waxay qayb muhiim ah ka ahaayeen daalacashada internetka ficil ahaan intii aan la aasaasin. Waxaan ku jiray sayniska kombuyuutarka sanado badan, ilaa iyo markii aan ahaa isticmaale MS-DOS iyo DR-DOS marwalba waxaa jiray kacsanaanta fayrasyada, in kasta oo xaqiiqda ah in waqtigaas Internetka uusan noqonin Rafaa maanta. Waqtigaas budhcad badeedda kala geddisan ee iibiya ciyaaraha iyo barnaamijyada waxa ku jiri kara fayras qaabeeya kombuyuutarkeenna, xannibay ama wax kale. Waqti ka dib Fayrasyadu wax badan ayey is beddeleen, iyagoo qaatay internet-ka oo xilliganna ah khayaano, basaasnimo iyo madax furasho Iyagu waa hubka halista gelin kara oo keliya qalabkeenna, laakiin sidoo kale macluumaadkeenna ugu qiimaha badan.
Norton iyo McAfee waa antivirus ugu da'da weyn, kaas oo maahan sababtaas tan ugu fiican, ee aan maanta heli karno. Laakiin sida laga soo xigtay Robert O'Callahan, oo ah injineer hore ee Mozilla, antivirus-ka kaliya ee runtii u qalmaa waa Windows Defender fayraska oo asal ahaan lagu rakibay kombiyuutarada oo dhan tan iyo imaatinka Windows 8.1. Laakiin waxay umuuqataa inuusan kaligiis aheyn kan xaqiijinaya, maadaama injineer kale oo amniga ka shaqeeya horumarinta Chrome, Justin Schuh uu si isku mid ah u sheeganayo.
Sida laga soo xigtay Robert ma jiro caddayn dhab ah oo ah in fayrasyada fayraska laga helo suuqa hagaajinta amniga uu Windows Defender na siiyo. Maskaxda ku hay in Windows Defender uu ku dhexjiro nidaamka iyo codsi kasta oo antivirus kale oo la rakibo waxaa laga yaabaa inuusan waxtar u lahayn sida kan hooyo. Robert wuxuu kugula taliyaa hadii aad leedahay antivirus inaad iska saarto oo aad kaliya isticmaasho midka udhashay.
Dhowr bilood ka hor, madaxa Karspersky wuxuu yiri Midowga Yurub waa inay baaraan in Microsoft ay jabineyso sharciyada kahortaga kalsoonida oo ay kujirto codsi antivirus ah noocyada ugu dambeeya ee Windows, wax la hubo inuu waxyeello badan u geysanayo shirkadaha amniga kombiyuutarka. Burburka ay sidoo kale xoojisay hadalada injineerkan Mozilla iyo injineerka Chrome.
