Before doing anything if you have not already done so, you should back up
all your important documents, personal data files and photos to a CD or DVD drive as some infections may render your computer unbootable during or before the disinfection process
. The safest practice is not to backup
any files with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.
Please follow these instructions: How to remove Google Redirects or the TDSS, TDL3, Alureon rootkit using TDSSKiller
-- For any files detected as 'Suspicious' (except those identified as Forged to be cured after reboot) get a second opinion by submitting to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.Step 7
- Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
Vista/Windows 7 users right-click and select Run As Administrator.
- When the program opens, click the Start Scan button.
- Any objects found, will show in the Scan results - Select action for found objects and offer three options.
- If an infected file is detected, the default action will be Cure...do not change it.
- Click Continue > Reboot now to finish the cleaning process.<- Important!!
- If 'Suspicious' objects are detected, you will be given the option to Skip or Quarantine. Skip will be the default selection. Leave it as such for now.
- A log file named TDSSKiller_version_date_time_log.txt will be created and saved to the root directory (usually Local Disk C:).
- Copy and paste the contents of that file in your next reply.
instructs you to scan your computer using Malwarebytes Anti-Malware
. Don't forget to check for database definition updates
through the program's interface (preferable method
) before scanning.Malwarebytes' may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
Note: If Malwarebytes' encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes' from removing all the malware.
- After completing the scan, a log report will open in Notepad.
- The log is automatically saved and can be viewed by clicking the Logs tab .
- Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows the database version and your operating system.
- Exit Malwarebytes' when done.
-- Some types of malware will target Malwarebytes Anti-Malware and other security tools to keep them from running properly. If that's the case, please refer to the suggestions provided in For those having trouble running Malwarebytes Anti-Malware
as you may need to rename it or use RKill
by Grinler.IMPORTANT NOTE
: Using more than one anti-virus program is not advisable
The primary concern with doing so is due to conflicts that can arise
when they are running in real-time mode simultaneously and issues with Windows resource management. Even if one of them is disabled for use as a stand-alone scanner, it can affect the other and cause conflicts
. Anti-virus software components insert themselves into the operating systems core and using more than one can cause instability, crash your computer, slow performance and waste system resources
. When actively running in the background while connected to the Internet, they both may try to update their definition databases at the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.
Each anti-virus may interpret the activity of the other as suspicious behavior
and there is a greater chance of them alerting you to a "False Positive
". If one finds a virus or a suspicious file and then the other also finds the same, both programs will be competing over exclusive rights on dealing with that virus or suspicious file. Each anti-virus may attempt to remove the offending file and quarantine it at the same time resulting in a resource management issue as to which program gets permission to act first. If one anit-virus finds and quarantines the file before the other one does, then you encounter the problem of both wanting to scan each other's zipped or archived files and each reporting the other's quarantined contents. This can lead to a repetitive cycle of endless alerts that continually warn you that a threat has been found when that is not the case.
Anti-virus scanners use virus definitions to check for malware and these can include a fragment of the virus code which may be recognized by other anti-virus programs as the virus itself
. Because of this, many anti-virus vendors encrypt their definitions so that they do not trigger a false alarm when scanned by other security programs. Other vendors do not encrypt their definitions and they can trigger false alarms when detected by the resident anti-virus. Further, dual installation
is not always possible because most of the newer anti-virus programs will detect the presence of others and may insist they be removed prior to download and installation of another. If the installation does complete with another anti-virus already installed, you may encounter issues like system freezing, unresponsiveness
or similar symptoms while trying to use it.
To avoid these problems, use only one
anti-virus solution. Anti-virus vendors recommend that you install and run only one anti-virus program at a time
You can always supplement your anti-virus by performing an Online Virus Scan
