Ist com.com sicher?

There is a very disturbing trent on this site of people with no I.T. background or actualy factual information about the site saying "yeah it's safe it is owned by a big company". Just because you have heard of the site does not make it safe. I have ***** blocked on my computer and firewall due to multiple attempts from the site to install adware. I also download nothing from the site for the same reason, I have seen files uploaded to the site that were malware free when uploaded and contained malware after download.

I'm glad to see here that it's a good site. But I was damn scared when I a Google search led to "Tech Republic", which I know from earlier, and it opened on techrepublic.*com.com*. It sure looked like a scam domain to me... like wot.com, which I got to by mistake before getting here.
