Sohana worm (a.k.a. Yahlover worm) spreads with help of chat programs (instant messengers) and through network shares. It is capable of changing registry values in order to get more control of a computer.

Yahlover is able to camouflage its activities. This makes the worm difficult to notice, therefore difficult to remove. Yahlover may disable anti-virus programs and trick firewalls into taking the infection as it was regular software. It also runs automatically on boot.

Yahlover is dangerous worm because its purpose is downloading other malwares. It is able to download and execute various trojans. Yahlover worm usually downloads infections from diesam.moe.hm, admin.waverevenue.com, bhxtakekep.net and sousi.extasix.com. Block these sources using your HOSTS file if you suspect Yahlover infection.
