computer slow!!

All of a sudden I have had massive problems with my computer, very slow and random browser closings.

I have run all the steps and now run a hijack this and here is my log.

 

Also, everytime I close Internet Explorer a box comes up that says an error has occured and it has to shut down (even though it's already closed) and asks me to submit an error report.

Whenever I boot Windows Installer pops up trying to install photo gallery and it takes about 10-15 cancels to get the installer to stop popping up.

How do I fix these two things?

 

You have both Norton and McAfee installed. Pick one install the other. Never have more than one Antivirus program installed on your computer the will cause conflicts.

You have two instances of Windows installer running. this is caused by an imcomplete instal of one or more programs that use MSI, probably MS programs like office.

Your log gives no indications that this is a Malware problem.

Post this in the Software forum as this looks like a software problem.
