Video playback is choppy

Hey...hoping someone might be able to take a stab at this problem I've been having. I recently purged my laptop of a few viruses and a nasty Trojan whose name I don't recall. The "Blue Screen Of Death" no longer appears! The only problem I have is that my video playback is choppy (audio is fine). My CPU usage while playing an AVI or DVD is @30-40% (at most). I use VLC player. I've installed, reinstalled, burned incense and howled at the moon over this one. PLEASE ANY THOUGHTS???

Happy Holidays and welcome to Lockergnome.

There doesn't seem to be any spyware in the log file. Did you have this problem before the virus issues? Also, was this before or after installing Sunbelt's antivirus program? I see that this program has used up a lot of resources as well from my searches.

If you want, you can run the following scans to see if anything else is picked up:

Download Malwarebytes ' Anti-Malware at http://www.besttechie.net/tools/mbam-setup.exe or http://www.majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html Double-click on mbam-setup.exe to install the application.

* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Full Scan, then click Scan.
* The scan may take some time to finish, so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to restart (see Extra Note below).
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy & paste the entire report into your next reply.

Extra Note:
If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately.

Go to http://www.bleepingcomputer.com/combofix/how-to-use-combofix and follow the instructions on how to install the Recovery Console and run ComboFix. Go through all the steps until posting the log part. Post the combofix log here.
