I don't know about nowadays, but Toshiba used to be the worst.
Legend has it, that Toshiba made more money off installing the cruft than the machines themselves.
Around 2008, I was in a crunch and needed a laptop, like immediately. So, I went to Best Buys and bought a new Toshiba.
The salesman asked if I'd like to have their service department remove the 'ad-ware'. He said it cost $30,00 USD.
I asked how long it takes, He said, about 30 minutes. I said, no, that's okay. I'm in a hurry, and I'll do it myself.
Three (3) days later, I finally got the last of the cruft purged from my shiny new lappy.
If I'd known what was involved, I would have gladly paid the $30 ransom, with a kiss.
