Well, your computer is clean imo. But you have some security holes to fix.
To begin it appears that not all your software is ahum... entirely legal. Software piracy is a good way to pick up malware.

You need to install the latest version of Java. Having the latest version is important to take advantage of fixes that have eliminated security vulnerabilities.
  • Go to Start > Control Panel
  • Double-click on Add or Remove Programs
  • Look for entries that say Java, Java RunTime Environment or J2SE.
  • Uninstall all of them that are not named Java (TM) 6 Update 25

After doing this, you can go to java.com, click on Free Java Download and proceed from there to install the latest version of Java (currently Version 6 Update 25).

After installing Java, go to Start > Control Panel > Java to open the Java Control Panel.
Under the General tab, Temporary Internet Files click Settings, then click Delete Files.
Select both options and click OK to delete the Java cache.

====================

You have an old version installed of Adobe Reader. This old version has security issues.
I recommend that you uninstall Adobe Reader through Start > Control Panel > Add or Remove Programs.
After that you should install a PDF reader that is more secure.
Please note that Adobe Reader has a history of security issues and is a prime target for malware writers due to its popularity. You might want to consider installing a non-Adobe PDF reader. Your choice!
  • Adobe Reader 10.0. The last and most safest version of Adobe Reader.
  • SumatraPDF. Very small and very light PDF viewer.
  • PDF XChange. Also available in 64-bit version if you have a 64-bit OS. Can be installed as portable.

====================

Time to uninstall used tools.
  • Go to Start > Run and type or copy/paste Combofix /uninstall (note the space before the "/").
  • Double click OTL.exe to run it again and click the CleanUp button.
  • If we used any other tools and they still remain on your desktop, please delete them manually.

Allright! Now that we have you cleaned, we´ve got to make sure you stay clean.
Let me provide you with some recommendations:

1) Keep your Windows up-to-date. Windows Autoupdate should be ON (see Start >> Control Panel >> Security Center). An alternative way (but more time-consuming) is to periodically visit http://windowsupdate.microsoft.com. Hackers are looking every day for new security holes. Microsoft keeps patching them. You cannot fall behind in this race, it will make your system vulnerable.

2) For your average daily computer activities, use a limited/standard user account. If you use Vista/WIN7 do not disable User Account Control (UAC). You would be amazed to know how much malware can´t touch you if you deny it admin rights. Create a separate password-protected administrator account that you use for admin activities, like (un)installing software.

3) Use a good antivirus. There are various free ones, you cannot go wrong with either of the following three:
  • Panda Cloud Antivirus. If you want your antivirus to be light on resources, I recommend Panda. Install without the toolbar.
  • Avira. 100 million users can´t be wrong. If you want high detection rates, this is your best free bet.
  • Avast! is a very complete antivirus, with modules like mailscanner and webshield.

4) If your computer has 1GB system memory or more, you should install a third party firewall, to replace the weak Windows Firewall. I recommend:

Note: you should run only ONE antivirus and ONE firewall. Running multiples of either is bad, it will cause slowdowns and/or conflicts.

5) Miscellaneous advice:
  • Stay away from cracks and keygens (look here for the why). Get free software instead. Gizmo is an excellent source of freeware reviews.
  • Navigate safely. Google Chrome is the safest browser available. However, Mozilla Firefox can be made extremely safe with the NoScript addon. Internet Explorer (always use version 8) can be made a lot safer with Spywareblaster (manual here).
  • The WOT (Webs Of Trust) addon will help you to stay on reliable webpages.
  • WinPatrol alerts you when changes are made in vital system areas. Especially good on light systems not running a third party firewall.
  • Make sure you have ways to recuperate your operating system and vital other data if its gets frustrated by malware and/or other problems. A Windows setup CD and recent backups/disk images will be priceless, if you find yourself in an unexpected tight spot.
