System is unstable and I think it's malware or a virus...

About a month ago my Firefox browser started acting up and is now to the point of crashing regularly. I've uninstalled and reinstalled it to no avail. My system in general has become much more unstable so I'm hoping one of you can get me any insight. My hijack this log is below:

Hello and welcome to the forum.
My name is Airscape and I'll be helping you with your malware issues.
The logs can take a while to research. Please be patient with me.

Take note of the following before we begin.

• Post to this thread only and please stick to it until I say your pc is clean.
• The instructions I give are for This computer only and should not be used on any other pc.
• Do NOT run any tools/scans unless I instruct you to.
• Try not to install/uninstall any programs while we work. This will add extra time researching your logs.
• If you have found assistance elsewhere and no longer require our help, please say so, and this topic will be closed.
• If you have any problems, please stop and ask before proceeding with any fixes.
• ALL USERS OF THIS FORUM MUST READ THIS FIRST

Note: As I'm still in training, everything I post must be checked by a teacher first. So there may be a slight delay in between posts.

Important:
Please be aware that removing Malware is a hazardous undertaking. I will take care not to knowingly suggest courses of action that might damage your computer. However it is impossible for me to foresee all interactions that may happen between the software on your computer and those we'll use to clear you of infection, and I cannot guarantee the safety of your system. It is possible that we might encounter situations where the only recourse is to re-format and re-install your operating system, or to necessitate you taking your computer to a repair shop.

In light of this it would be wise for you to back up any important files and folders that you don't want to lose before we start.

And I would like to know if this pc is used for business/work?

Thanks

Do you still need help?
