I once had the Google redirect problem resolved with the help of this nifty site and all of you nifty peoples!
I seem to have another problem.
(Vista Basic on a Toshiba L355 S7915)

Recently, while playing iTunes and doing hmwk I noticed that my notebooks internal fan was working pretty hard to keep itself cool. So I figured that Leaning the notebook with the vents facing open air would help. On the contrary, the fan got super loud (louder than I've ever heard) for about 5 or 6 seconds and then my notebook simply turned off. (I think thats called crashing) I turned on my computer and was met with a "Your computer did not shut down properly" screen and I selected the start up normally button. Once everything was up, I opened google chrome immediately and noticed that it was running painfully slow. I figured it was my school's internet connection so I checked my roommates laptop and his was lightning fast. I returned to my laptop and took a look at my Task Manager and saw that my CPU was running at 100% with about 90 processes running. I dont know much about computers but I'm sure that running at 100% with 90 processes running is not healthy. So I jumped on this here nifty site and read up on what the problem might be. I took some initial steps and I erased about 3 or 4 gbs of useless files, music, photos and programs from my hard drive. I then proceeded to run Disk cleanup and I defragged my laptop as the last step. Afterwards my computer was back to normal averaging about 15-30% of CPU usage with the occasional spike. About 2 or 3 days later Things had slowed down considerably on my computer while using chrome and I checked my Task Manager and sure enough the CPU was at 100%. I usually get an Skype toolbars crashed, or a Shockwave toolbar crashed message. And I cant find my battery icon!! It used to be on the bottom right of the screen but it disappeared somewhere. I ran Hitman Pro and it found no problems... So I'm a little stuck! I think I may have contracted a virus/malware/trojan/something awful somehow. Any help fixing any/some/all of these issues would be greatly appreciated!
Thanks in advance. ^_^

Hello, lets see what we can find out.

Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:
  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices
  • List Users, Partitions and Memory size.
  • List Minidump Files
Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using "Reset FF Proxy Settings" option Firefox should be closed.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1 <<<== Use this one first.

Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
