Hi there


Had a virus warning in Avast this afternoon: Threat: Rootkit: Hidden file (in C:\Windows\SoftwareDistribution\Dowload folder), which I accidentally deleted with Avast before having a proper chance to evaluate.


I am not getting any further virus messages in either Avast or MalwareBytes Pro, or MalwareBytes Anti-Root kit, but when I first run the latter I get a message "Registry value "AppInit_Dlls" has been found ....".  Note that I have no problem proceeding to run the tool.


Could you please assist me to:


1) Understand if the "AppInit_Dlls" message is an issue I should be concerned with; and

2) How I can double-check to ensure my system is no longer infected (or perhaps the initial threat was just a false positive?)


Thanks for your help.

FRST logs do not show anything obviously malicious, I only give new instructions for thorough scans to ensure we`ve missed no remnants of previous infections. If you are considering a re-install of the system obviously that is a better option as you will have a  clean slate, your choice I guess.

Hi Kevin


I've uploaded 3 of the files you asked for, but I'm having some issues running the Screen317 program.


There seems to be some issue with the file path when I run it from the desktop, so I'm not sure that it is actually scanning, despite the fact it produces a blank report at the end.


In regards to the ESET finding, am I correct in assuming that these are not significant issues, since they represent a potential issue only if the software is installed - currently they are just downloaded files sitting in my directory.  Should I simply delete them, or do they need specialist removal?


Not quite sure where to go from here with Screen317.


Thanks for your help

Just ignore Security Checks, could possibly be your security affecting the application. Regarding ESET, yes those installers are potentially bundled with unwanted extras, deleting them is good enough.


AdwCleaner need to be run one more time, on completion of the scan select and run the "Clean" function to remove unwanted entries...


Let me know if those steps complete, also if any remaining issues or concerns.....

Hi Kevin


Ran AdwCleaner and have attached report.


One final concern I have is when I do a Rootkit scan with Spybot (report attached).


I suspect the majority of the files are harmless, but I'm I'm not sure about the hidden file mentioned first in the log (file details in capture attached).


Any thoughts?

The ADS files are of no significance, the other hidden file I have no idea what that is. Maybe show hidden files and folders so you have access to it, then rename it. Right click on it, select rename, add .bak to the end.

If there is no effect to your system after renaming go back later and delete it.

Good to here that all is now ok, regarding security this is my own set up,


Windows own Firewall, Microsoft Security Essentials and Malwarebytes Pro. Windows FW and MSE are free, MB does also have a free version, however I prefer the pro version as it provides auto updates and realtime protection. Cost is about £20 for a lifetime license.


As an extra layer I also use WinPatrol, the free version is adeqaute for general home use. Available here: http://www.winpatrol.com/download.html


For my browser I use Firefox with these addons: Web of Trust, Adblock Plus, Flash Block, NoScipt, Ghostery. When Firefox is open select these keys together :- Ctrl - Shift - A that will access Addons manger, this gives access to find addons, use, start, stop or disable those features etc....

Before using NoScript read from this link http://noscript.net/ makes it easy to understand....

I also use the Professional version of Sandboxie, I believe there is also free version available. Visit this link http://www.sandboxie.com/ for access to d/l, also make sure to use the "Help and FAQ" option to understand its uses, specifically how to run your browser sandboxed!.


Maybe that info will be useful for you,
