Title: A possible False Positive?
Post by: Desiree859 on May 07, 2014, 03:00:14 AM
Hello!

I did a scan tonight and Avast said I had an infected file. The strange thing is it wouldn't let me repair it, remove, or do anything to the file. It's just... there. On the scan it says "Error Access is Denied" (5)

I've attached a screenshot for further information. It says it's from Skype but when I looked for that file it wasn't found to be on my computer. I am rather confused as to what this is. Is it a false positive?

Avast won't let me move the file to the chest or do anything with it so I can't do it that way. Also, I can't find the file on my computer. I searched for it but it says it doesn't exist.

probably has been deleted or is in a hidden folder

click the Start button, clicking Control Panel, clicking Appearance and Personalization, and then Folder Options.
2.Click the View tab.
3.On the Advanced settings, click Show Files, folders and hidden units and OK.

I did a boot scan but Avast now says there are no files infected. It says it was clean.

And Pondus I uninstalled Skype from my computer quite awhile ago.

Just because you think you uninstalled it doesn't mean you did. There are commonly leftovers. \Since boot-time scan didn't find anything. |You are most likely clean and that is a FP.

if you dont use skype any more, you may run CCleaner / reg cleaning to clear any leftovers 
if you dont want the toolbar ...use slim installer found at bottom of website here   http://www.piriform.com/ccleaner/builds
