Solved Blue Screen of Death after Defeating Virus

Regarding slow shutdown, I'd start with uninstalling Spybot altogether.

Then...
I recommend, you unistall Adobe Acrobat Reader, which is a resource hog, and install FoxIt Reader: http://www.filehippo.com/download_foxit/, which is much smaller, and faster. It does very same thing.
Make sure, you run "custom" install, and opt out from installing any extra toolbars.

Now, let's disable couple of unnecessary startups (no actual programs will be removed).

Re-run HJT and checkmark following items:

O2 - BHO: (no name) - {3CA2F312-6F6E-4B53-A66E-4E65E497C8C0} - (no file)
O4 - HKLM\..\Run: [Adobe ARM] "C:\Program Files (x86)\Common Files\Adobe\ARM\1.0\AdobeARM.exe "
O4 - HKLM\..\Run: [DivXUpdate] "C:\Program Files (x86)\DivX\DivX Update\DivXUpdate.exe" /CHECKNOW
O4 - HKUS\S-1-5-19\..\RunOnce: [mctadmin] C:\Windows\System32\mctadmin.exe (User 'LOCAL SERVICE')
O4 - HKUS\S-1-5-20\..\RunOnce: [mctadmin] C:\Windows\System32\mctadmin.exe (User 'NETWORK SERVICE')
O4 - Global Startup: OnlyWire.LNK = ?

Click "Fix checked" button.

After making all those changes, restart computer and see how it goes.

 

Not a problem
Just let me know, how your shutdown time is now.

 

Are you still out there?

 

I'm glad to hear good news
Then, it's not too good to just leave a topic for several days without knowing me what's going on and running final steps.
Which browser are you having problems with?

I see

Are you done with those last steps?
Is computer doing OK?

I assume, you use IE8?
Try to reset it.
Tools>Internet Options>Advanced tab, click on "Reset" button.
Restart computer.

 

Any other problems beside Firefox?

Close Firefox. Go Start>All Programs>Mozilla Firefox, click on Mozilla Firefox (safe mode). Use it this way for a while and see, if you still have problems.

 

Let me know...
