SpyBot 1.6.2 - installing questions

[Guest2]

I have two questions about SpyBot installation:

Question 1:
I tried updating my version of SpyBot by installing 1.6.2. During the installation, there were messages for two items which said they are Read Only:


SDHelper.dll
Tools.dll

My options were to try again, skip it, or cancel. I choose to skip it. SpyBot continued the installation and was finished.
Will I have problems later on because those two files were Read Only?

Question 2:
I'm not 100% sure if it was SpyBot that asked if I wanted to install a Yahoo Toolbar. I was installing lots of updates today and should have made a note. Whatever the case, I chose NOT to install the Yahoo Toolbar. During installation, I could see screens that said Yahoo Toolbar was being added! Afterward, Firefox is now showing the Yahoo Toolbar. If it's SpyBot that added it, I'm here to ask how I may get the Toolbar to remove itself.

Thanks

OS: Vista Home Premium, SP 1, 32 bit
Firefox 3.0.5
SpyBot 1.6.2

Question 2 has been answered: It was easy to remove the Yahoo Toolbar under the Add-ons area of Firefox. I should have thought to look there first before posting.

I did retry and it seemed to be OK.
Skip it would not change anything unless PepkiMK changed thiose files. Hopefully he'll respond.
If unaltered, then the files were neither deleted nor replaced I'm pretty sure.
Good luck
