AdAware stopped updating years ago...
Yes. I know.
But it’s still available online.
Useless. But still there.
And I suggested running Malwarebytes in ‘safe mode’ because some trojans will not only hijack your browser, but can and will prevent you from running any Anti-Virus or other scan program.
I’ve had it happen twice.
I now run Microsoft Security Essentials.
Haven’t had a problem since.
