There are others posting here but dropped in to also confirm that I firsthand witnessed this. I had a single device and had to do a fresh install from factory settings. This meant I had about 30 mins before my 500kbps connection would grind to a crippling halt from all the accumulated malware. This meant I had to incrementally procure protection, save it, then fresh install and repeat until I could access the Internet safely. I don't miss those days.
