HELPFUL HINT

When dealing with viruses, or malware there are some dangers involved that can include loss of data, to corruption of the OS. These dangers can take place from the virus, malware, etc. itself or even during the removal process. Though in most cases it is rare, there is still a chance. If you have important information, you may want to back it up to an external system prior to starting this if you decide to continue.

Some malware may take multiple steps to resolve, or in the worst case, reloading/reformatting your system entirely. We can't stress enough the importance of backing up any data you don't want to lose. Whatever your method, it is an important step to do this before beginning any malware fix. It is also important to perform everything in the order listed. Sometimes one step requires the previous one.

Important: Make sure you read through everything prior to starting so you know what to do. You may want to print out the instructions as there are several times you will have to reboot.

Do not run any of these at the same time. Run each individually as they may interfere with each other.
