If you have used malware on PlayStation ® 3, you should stop using them immediately, please delete. If you are using malicious software, you may not be able to connect to the Sony Entertainment Network and PlayStation ® 3 from PlayStation ® Network in the future.
I found the above quote from the Japanese translation to be quite funny.
Home = Malware
Forced Singstar = Malware
There is even more unneeded junk on the PS3....
