False positives?
« on: April 26, 2014, 03:42:36 PM »
Just ran V8.0 on a Mac running OSX 10.9.2 and got a bunch of alerts all in the invisible Spotlight directory, all are txts with the tag HTML:BANKFRAUD-BUT with variations and a couple identified as Phishes. Are these false positives?

I'm not sure that you can with small number of posts... it's an antispam measure that, unfortunatelly, blocks good users.

Yes you can, in the Reply window, use the Attachments and other options below the text window. A new dialogue will open to attach files and images. There are limitations on the image types, file types and file size/s.

Hi,
Thanks for the info. However, the 30 or so 'infections' reported have since disappeared. They were in an invisible dotSpotlite directory and in theory anyway, were all text files of caches but I couldn't open one, so I doubt they actually existed. So I ran Onynx and deleted Spotlite caches etc. Ran Avast on the entire drive and came with a bunch of embedded, mostly Windoze attachments to Word files I had from way back, which I deleted. system seems clean now, so it seems to work.

I just wonder how much of an overhead it puts on my machine (21.5-inch, Mid 2011, osx 10.9.2, 16gig ram)?

Sorry I can't help you with the overhead question as I don't have a Mac and not knowing the CPU (Processor), doesn't make it any easier.

Hopefully a Mac user can join the topic and answer the question with the benefit of knowing the CPU also.

Well given the CPU and RAM, that would be a good specification for a Windows version of avast. So I would expect the same from the avast 4 Mac version.

Though load is also influenced by the number of other applications that you have running.

I still hope a Mac user can confirm this.
