there a malware in the wallet infecting all computers
Please clarify the essence of the malware? What kind of wallet are you talking about? There are several options PHORE Wallet.
Several antivirus programs detect a cgminer signature in a multitude of pivx/dash based Masternode wallets. That's a false positive.
false positive and 'infecting all computers' are totally different from my perspective.
false positive means something that is not harmful while 'infecting all computers' are a different thing.
