>Screen sharing software was just one more thing to go wrong on their computers. This way, I don't have to worry about whether they have a version with a critical vulnerability, or if they'll fall for a social engineering attack and click on a teamviewer invite.
It's no more of a risk really with TeamViewer installed. An attacker can use gotomypc or similar or just send a TeamViewer invite binary (or link to download it and give the attacker access).
Wasn't there some story a few months back about TeamViewer accounts being hacked in some unknown way and their access used to infect machines? Was that ever clearly resolved? (I remember speculation of TeamViewer themselves being compromised, or just a massive password-reuse attack, or ...)
It's never been clearly resolved, but also hasn't developed. So far it looks like TV was correct and the breaches were the result of password reuse from other sites who did have passwords compromised.
