McAfee Anti-Virus Error

OK...simple problem: the program has no write-clearance for its installation directory.
Right Click the EXE and "Run as Administrator"

OK..it doesn't really look bad. the only entry I could find that doesn't have to be there is this one:

O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - (no file)

Seems to point to some Yahoo Toolbar. Since you have a restore point..if you want to delete it... check that one (and ONLY that one) and then click the Fix Button.

Is everything else okay? Thanks for your help. The computer's fan is still on constantly so there must be other problems as well. I think dell support center shouldn't be there as I uninstalled it a few days ago.

You're very welcome.

The fan on the computer is still on constantly, though. I uninstalled Dell Support Center a few days ago, so do I need to fix that too? I also never finished installing cccleaner.

The fan is on...OK, basically that's a good thing the CPU generates heat and needs to be cooled from the moment you start the computer.
What's the problem? is it too loud? If so..is it running full speed constantly? In that case there might be a setting in the BIOS.
Don't worry about the CCleaner if you don't intend to use it, don't install it
On the other hand it's much safer than all the other One click cleaners out there. Just leave the registry alone and don't click on things you don't (yet) understand and you're golden.

The fan is working normally, but it used to stop now and then. Now it doesn't stop at all. If Dell Support Center and cccleaner are on the list, do they need to be removed because I unstalled DSC and cancelled the installation of ccleaner.

Oh I see what you mean..let me have another look

you mean this
O4 - HKLM\..\Run: [dellsupportcenter] "C:\Program Files (x86)\Dell Support Center\bin\sprtcmd.exe" /P dellsupportcenter

and this

O16 - DPF: {49312E18-AA92-4CC2-BB97-55DEA7BCADD6} (WMI Class) - http://support.dell.com/systemprofiler/SysProExe.CAB

It's save to leave them alone but you can delete them if they give you any grieve.
The Ccleaner has no entry in that list (the list holds mainly registry entries about drivers and other stuff that gets automatically loaded i.e so called "Browser Help Objects"..ccleaner does no such thing) so there is nothing to do here.
