is a troubleshooting mode designed to start Windows with minimal drivers
and running processes
to diagnose problems with your computer. This means some of the programs that normally start when Windows starts will not run.Why use safe mode
? The Windows operating system protects files
when they are being accessed by an application or a program. Malware writers create programs that can insert itself and hide in these protected areas
when the files are being used. Using safe mode reduces the number of modules requesting files to only essentials which make your computer functional. This in turn reduces the number of hiding places for malware
, making it easier to find and delete the offending files when performing scans with anti-virus and anti-malware tools. In many cases, performing your scans in safe mode speeds up the scanning process. Scanning in safe mode was a recommended course of action years ago before
malware writers began to employ more sophisticated techniques to counter removal efforts in that mode.Why not use safe mode
? Some security tools like anti-rootkit scanners (ARKs) and programs with anti-rootkit technology use special drivers which are required
for the scanning and removal process. These tools are designed to work in normal mode because the drivers will not load in safe mode which lessens the scan's effectiveness. Other security tools are optimized to run from normal mode
where they are most effective. For example, Malwarebytes Anti-Malware is designed to be at full power when malware is running so safe mode is not necessary when using it. In fact, Malwarebytes loses some effectiveness
for detection and removal when used in safe mode. For optimal removal, normal mode is recommended
so it does not limit the abilities of Malwarebytes.
Scanning in safe mode prevents some types of malware from running so it may be missed during the detection process. If the malware is not related to a running process (i.e. malicious .dll) it probably will not make a difference performing a scan in normal or safe mode. A hidden piece of malware
such as a rootkit
which protects other malicious files and registry keys from deletion may not be detected in either mode without the use of special tools. Additionally, if the scanner you're using does not include definitions for the malware, then they may not detect or remove it regardless of what mode is used. Also keep in mind that there are various types of malware infections which target the safeboot keyset so booting into safe mode is not always possible.
Your issue will require further investigation and a more comprehensive look at your system. Many of the scanning we use in this forum are not capable of detecting (repairing/removing) all malware variants so more advanced tools are needed to investigate. Before that can be done you will need to create and post a DDS log for further investigation.
Please follow the instructions in the Malware Removal and Log Section Preparation Guide
starting at Step 6.
- If you cannot complete a step, then skip it and continue with the next.
- In Step 6 there are instructions for downloading and running DDS which will create two logs. (Note: Windows 8.1 Users will not be able run DDS and create a log)
When you have done that, post your logs
in the Virus, Trojan, Spyware, and Malware Removal Logs forum
, NOT here
, for assistance by the Malware Response Team.
Start a new topic, give it a relevant title and post your log(s) along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. If you cannot produce any of the required logs, then still start the new topic and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happened when you tried to create them. A member of the Malware Removal Team will walk you through, step by step, on how to clean your computer.
After doing this, please reply back in this thread with a link to the new topic so we can closed this one.
