Sorry if this is off topic, but has anyone encountered this: my sister downloaded Avast (she had a lic but her computer was rebooted and stripped of apps, so she needed to reinstall it).
Many issues later, I saw that she had downloaded Avast four times (4 times, don't ask), BUT, another app downloaded 4x also (tethered?), without her help, called SpeedyPC Pro.
Then, she claims, it mysteriously installed itself, and then caused many conflicts including disabling Google and Chrome at various times and popped up all the time. Of course I uninstalled it and now the browsers seem to work ok.
What could this be?
Thanks!
