I am using the Avast antivirus in my computer and there is one problem with this that I am facing. It is warning me that there is Rootkit: hidden folder and I need to delete that. So I selected yes and I donít know if it deleted that or not. But after about 10 minutes of use It again showed me the same thing and this time I selected ignore it. I did a scan of the system by right click feature and it comes up as clean. I am wondering that if this is the false positive. So I am posting it over here. If you know anything about this then please let me know that. I will be thankful to all the replies for this.
