Hi and welcome to SevenForums,
I don't know about the av you have installed but possibly resetting the browsers might help ?

Welcome to Seven Forums pfw415. This is likely caused by Sophos removing it, rather then it being uninstalled correctly. Sendori support suggests;

"If you’ve already uninstalled Sendori but are still seeing Sendori appear while browsing the internet, the easiest way to correct this is to reinstall the most recent version of Sendori then uninstall it again:
1. Download and install the most recent version of Sendori by downloading it at Sendori
2. Uninstall Sendori.
3. This should correctly update your computer to previous settings. You may need to restart your browser and/or computer for the changes to take effect."

Before trying that though, try this. Let's flush the DNS cache and restore MS's Hosts file. Copy and paste these lines in Note pad.

@Echo on
pushd\windows\system32\drivers\etc
attrib -h -s -r hosts
echo 127.0.0.1 localhost>HOSTS
attrib +r +h +s hosts
popd
ipconfig /release
ipconfig /renew
ipconfig /flushdns
netsh winsock reset all
netsh int ip reset all
shutdown -r -t 1
del %0

Save as flush.bat to your desktop.

Right click the .bat file and choose to Run as Administrator. Your computer will reboot itself.

I would also d/l and run AdwCleaner

AdwCleaner Download (Choose the Download Now @BleepingComputer link)

If unsure what it will delete, post the log file that AdwCleaner creates.
