Some time ago, my chrome was hijacked to the
any searchsearch page, and the experience was very bad. I found a plugin called
TotalSearchToolboxin Settings> Extensions . After disabling it, the world was quiet. But within a few days, the malicious plugin resurfaced and infected Chrome, Firefox and Safari at the same time.
This time I went online for help and found that this was a notorious plugin, and it was more difficult to get rid of , and I had to manually delete related files.
