my computer's infected please help !

Grif, I'm a newbie to computers and learning as I go, by reading forums such as this. From those such as yourself(cnet moderators/staff), experienced users and others also new to computers and security issues, I've downloaded/installed all my security applications for Free, thanks to Editor and User Reviews. So far I've been fortunate in comprehending most details in using these applications.
I am currently using IE7(not really happy with this browser..any advice on others?)..Windows XP/SP2..CCleaner..SpywareBlaster..Ad-Aware..SpyBot S&D..and Avast AV. Again, Freebies that are highly rated and so far, keeping my computer secure(I Update and Scan weekly).
I downloaded and installed what you suggested to earlier poster here, Malwarebytes' Anti-Malware, for more security against spy/ad/malware yesterday. My question is that after running the initial full scan with Malwarebytes', in which five(5)infections were discovered, I was under the impression from past readings that one should never delete nasties if not sure what they are, but instead Quarantine/Isolate/Put In Chest..etc..until we are sure? Is this true? But my main question, if so true, How Do I put the 5 infestations in Quarantine in the Malwarebytes' Anti-Malware app?
I could not find answer here at CNET nor at Malwarebytes' site. Please forgive me if I intruded in this thread but this was only Subject I could find in relationship to Malwarebytes' Anti-Malware.

Thanks In Advance.

From memory I believe Malwarebytes will automatically place any infections/malware in "Quarantine" from where you can investigate, delete or restore the items as you choose.

I have never found anything other 3 trojans recently quarantined but later found to be false positives... Malwarebytes promptly issued and update correcting the problem... I then restored these from quarantine.

Hope this helps.

See the Malwarebytes forum link below to see that infected files are "Removed" to the Quarantine folder.

In regards to automatically deleting items, that depends on the items that's found.. I've done this enough that I'm familiar with what IS and what might not be a true infected file. I can usually tell if the file is a "bad" one. Still, there are occasional false positives and as such, it's not a bad idea to keep them in a Quarantine location till you can decide on the effects their deletion is caused.

As to other browsers, there are a number including Firefox & Opera.. Personally, I like the free Firefox browser.. Download it, install it, and give it a try:
