The link to the Kaspersky article actually stated that there were sites that were distributing software that installed malware - not that the sites themselves were installing the malware in people’s computers. You should take the trouble to read your own sources before quoting it.
The tweet from the user clearly stated that they had a problem with the Skype installer, which they had downloaded while visiting MacUpdate. The user mistakenly believed that this installer file had been changed in some way by MacUpdate, not understanding that the installer they downloaded came directly from Microsoft - and had nothing to do with MacUpdate. If you have any doubts, it’s easy to clear it: visit the Skype listing at MacUpdate and do the download yourself. You will see that you are re-directed to the publisher’s servers for the download.
Moreover, if you were a regular visitor to MacUpdate, you’d see that it’s littered with notices of users who make the same mistake, and the usual response from MacUpdate staff, stating exactly what I just told you here. MacUpdate staff are actually nice enough to contact the software publishers, and let them know, too - and the software publishers have been known to thank MacUpdate publicly for this.
If your only source of security information is a site by Kaspersky, I’d suggest you do a bit more research. But most importantly, we are not talking about security here: we are talking about the reputation of MacUpdate, a well-established, well-known and extremely well-regarded site in the Mac community worldwide. You have shown to know very little about the site, and yet, it is you who wants to cast aspersions.
Worse still: phrases like “I hope your work is not on IT”, and “…is just talking to a wall” are clearly meant to be insulting, which is sad, and totally unnecessary.
We’re here, supposedly, because we like Gogs, and we’re all, in our way, and using the knowledge we have, trying to help promote it and advance it. I’m trying to do my part with the suggestions I’ve provided. To someone well-entrenched in the Mac community, as I am, these suggestions would seem trivial and obvious - just like using Kaspersky products would seem obvious to someone in the Windows world.
