You can leave the O15s. I assume you've made no fixes with HJT yet.

Can you keep McAfee firewall and not have the AV package? If so, sure if you like it and are comfortable with it, go ahead. It appears as though portions of McAfee's AV product are still installed.

One other thing to note about software you have on your system, is about MS's product:

MicroSoft AntiSpyware Program:

Because of recent changes in the way this program now defines and detects spyware/adware it is no longer recommend as a spyware removal tool. Microsoft as downgraded several adware/spyware programs that it used to detect and remove and now lists them simply as “Ignore”

These are some of the adware/spyware programs that this program will NOT prompt you to remove. Claria, 180Solutions, WhenU, New.net, most WhenU apps, eZula,TopText, Gain/Gator, and Webhancer. These are all known adware/spyware programs and hijackers. Basically this product can no longer be trusted!! I recommend you remove it

Here are some other tools which will do the job quite well:

AdawareSE (free)
Spybot Search and Destroy (Teatimer Enabled) (free)
IESpy-Ad (free)
SpywareBlaster (free)
WinPatrol (free)
CounterSpy (free trial).

After you've decided on these issues, please continue with the instructions, and post new logs.
