Google links redirecting to strange sites

Hello there... I'd appreciate your help with the following problem.

Recently, my browser started arbitrarily redirecting to strange sites when I click a link or enter an address in the address bar. It is happening with all browsers I use (Google Chrome, Firefox, IE).

There does not seem to be a pattern to the strange sites that I am redirected to... they are random.

Also, this doesn't happen every time I click a link... only sometimes. It does consistently happen when I click links from a web search though (Google or otherwise).

I am on Windows Vista.

Otherwise, my PC appears to be functioning normally.

Thanks,
Sarah

Please follow these instructions: How to remove Google Redirects or the TDSS, TDL3, Alureon rootkit using TDSSKiller

• Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
  Vista/Windows 7 users right-click and select Run As Administrator.
• When the program opens, click the Start Scan button.
• If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
• Ensure Cure is selected, then click Continue > Reboot now to finish the cleaning process. <- Important!!
  Note: If 'Suspicious' objects are detected, you will be given the option to Skip or Quarantine. Skip will be the default selection.
• A log file named TDSSKiller_version_date_time_log.txt will be created and saved to the root directory (usually Local Disk C:).
• Copy and paste the contents of that file in your next reply.

-- For any files detected as 'Suspicious' (except those identified as Forged to be cured after reboot) get a second opinion by submitting to Jotti's virusscan or VirusTotal. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.

Step 9 recommends that you scan your computer using MalwareBytes to remove any traces that may still be present. After performing that step, please post the complete results of your scan for review.
