Hello! Looks like my PC picked up something along the way. My browser, Firefox, keeps redirecting when I click on a search result link in Google. I have to go back and then reclick the link. Who knows what else is going on behind the scenes? I hope someone will help!

there is nothing obvious showing in the FRST log, but let's run a couple more scans to see if we can find anything that is lurking

please run the following:

Please download TDSSKiller.zip
  • Extract it to your desktop
  • Double click TDSSKiller.exe
  • when the window opens, click on Change Parameters
  • under ”Additional options”, put a check mark in the box next to “Detect TDLFS File System”
  • click OK
  • Press Start Scan
    • If Malicious objects are found then ensure Cure is selected
    • If TDLFS File System/TDSS File system is found then ensure Cure is selected (if cure is not available, choose skip)
    • Then click Continue > Reboot now
  • Copy and paste the log in your next reply
    • A copy of the log will be saved automatically to the root of the drive (typically C:\)


NEXT


Please download Junkware Removal Tool to your desktop.
  • Shutdown your antivirus to avoid any conflicts.
  • Right-mouse click JRT.exe and select Run as administrator
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next message

Alrighty... my browser seems to be working correctly, although only time will tell if it's truly fixed. The rerouting issue has been intermittent since it started happening. As requested, here are the three log files that were created...

Thanks for hanging in there with me and sorry for the delayed reply. It seems weekends are for camping... ;)

Here are the requested logs. The time and date on the AdwCleaner log and mbam log are incorrect. For some readon, the time had gotten screwed up on my PC.
