Don’t know about any of the businesses. But if you come across it on a website, a popup or the like, DO NOT, again DO NOT fall for it. There’s a reason why someone’s offering it for free. Usually it’s a scam virus that gets you to ‘donate’ money to ‘complete’ the ‘removal’ of viruses it ‘found’. – No, there were no viruses before. You just ‘installed’ it!!!
I do removals (actually for a charge, and no, I’m not advertising it here, there, or anywhere) so I know the ropes. Most things for free are for a reason…
