If none of the tools you have used thus far are finding any malicious files or not successful at removal, this issue will require further investigation. Many of the tools 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 you to create and post a DDS log for further investigation.
Please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help
- If you cannot complete a step, then skip it and continue with the next.
- In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.
When you have done that, post your log
in the Virus, Trojan, Spyware, and Malware Removal Logs forum
, NOT here
, for assistance by the Malware Response Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the Malware Response Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.
Start a new topic, give it a relevant title and post your log 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. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the Malware Response Team.
BTW, Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons: Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable
The Windows registry
is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component
because it is where Windows "remembers
" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable
. For a more detailed explanation, read Understanding The Registry
. Not all registry cleaners are created equal
. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry
". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work. Not all registry cleaners create a backup of the registry before making changes
. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE
making any changes to the registry. Improperly removing registry entries can hamper malware disinfection
and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable
to removal tools. The usefulness of cleaning the registry is highly overrated and can be dangerous
. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results
Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily
could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great
