Hello, I have been having some problems with my navigators recently (safari and chrome). It all started when I downloaded several third-party apps to try to recover some important files I deleted accidentally. The apps were all safe, except for one that Google warned me about (I don't remember its name or where I downloaded it from, I was desperate at the moment).
Google said it could be malware and that it would try to add extensions to Chrome, however, I thought it was the general Google kind of warning.
However, now I am having troubles with an unwanted tab opening up every time, it doesn't lead to anywhere, it just opens and then closes automatically. I deleted and reinstalled Google Chrome, deleted all extensions, reset Chrome, ran Malwarebytes Anti-malware for mac (it found some issues at first, I got rid of them. Now when I run Malwarebytes it says it did not find any malware), none made a difference.
I deleted cookies and cache from Chrome, and now the unwanted tab won't open, but there is always this warning on the top right "This page is trying to load scripts from unauthenticated fonts."
Another thing that worries me is that there are some files on Finder that did not appear before (it looks like their opacity icon is down as if they were not real folders as if they were hidden). For example, when I open my external HD on Finder, there are 4 files like this (.com.apple.timemachine.donotpresent ; .fseventsd ; .Spotlight-V100 ; .Trashes ; this last one, .Trashes, has an arrow icon on the bottom right of the folder icon, as if it said the folder is being downloaded, also it won't let me open the .Trashes file, it says I have no permission to see its content).
I am worried because I work with this computer, I do freelance with video editing, so I am afraid it might damage my mac or storage devices, make me lose important work, or even get hold of important info as account passwords.
If you guys could help me, it would be the best thing ever hehe, I am really desperate about this.
