what about "mac cleanup"and Tapsnake; CronDNS; Dubfishicv

hi,

I was for a long long time on Internet between eBay and aliexpress, and I received many alerts with the panic-sound of virus alert.

I was asked to clean up my mac infected at 33,2% as formulated in the alert page.

According to the alert, these viruses were found Tapsnake; CronDNS; Dubfishicv

I was asked to download mac cleanup to solve the problem I think it's Mac keeper ?!

Of course I didn't, but I want to know what's true about this ?

what shall I do know ? I have sophos wich didn't react to the supposed intruders.

please help
