False positive or malware?
« on: February 09, 2017, 08:42:07 AM »
I got the following popup twice on start up before I connected to the internet. Is this a false positive or should I be concerned about malware?

svchost.exe (Service Host, or SvcHost) is a system process that hosts multiple Windows services in the Windows NT family of operating systems. (See: https://en.wikipedia.org/wiki/Svchost.exe )

If avast is telling you svchost is infected, you're infected.

Please run the following and tell us how your system is.

Open notepad by pressing the Windows Key + R Key, typing in Notepad in the Run dialog and then pressing Enter.  Please copy the contents of the Code box below. To do this highlight the contents of the box and right click on it and select copy (or you can just click on the (select) next to Code Box). Paste this into the open notepad. Save it to your desktop as fixlist.txt
 
Code: [Select]
Start
CreateRestorePoint:
EmptyTemp:
CMD: bitsadmin /reset /allusers
End

NOTE. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

Run FRST64 by right clicking on the FRST64.exe file, selecting "Run as Administrator..".  The User Account Control may open up; if it does, select Yes to continue to let FRST open and load. 

The tool will check for an updated version of itself every time it loads; please allow it to do this and the program will either inform you it is downloading an updated copy (and to wait until it is safe to continue) or show nothing (meaning there is no update found) and you can continue on.  Press the Fix button just once and wait.  The tool will create a restore point, process the script and ask for a restart of your system.



If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.

When finished FRST will generate a log on the Desktop (Fixlog.txt). Please attach it to your reply post.  Also, tell me how your system is running now.

131.253.61.66 was a false positive, you do not have to be concerned about being infected (unless there are other popups :) ).
