Panda
Antivirus 2010 is most annoying paid software I've ever seen. Pop ups of Panda 2010 on my
desktop in front of all windows were killing me. All those promotions,
get renew(even though I was stupid enough to buy it for 2 years and 1.5
years left), community news and other spam. I’ve disabled these messages
hundreds of times, but after each Panda update they were annoyed me
like new.
