As soon as antivirus software targets this malware, it crashes the affected computer and continues to mine Monero from behind the "blue screen of death."
However, depending on the quality of your antivirus software, the WinstarNssmMiner cryptojacking virus might meet its match. Products like Avast and Kaspersky Labs should be able to back off when the virus is detected, preventing things from going nuclear right away.
Weaker solutions, however, will trigger the WinstarNssmMiner's last resort option, and for those unaware that the issue os cryptjacking software, the infected computer will continue to mine crypto for the bad actors as the virus attributes the mining process to CriticalProcess and shuts everything else down.
Over half a million computers have been infected in three days with WinstarNssmMiner according to researchers from 360 Total Security, who note that it is based off the legitimate open-source mining project XMRig. Fourmining pools using the malware have mined 133 Monero so far, over $26,500.
