my laptops suddenly gone really slow.ive not downloaded anything dodgy but my fella plays on facebook games and stuff,is there anything i can do to speed it back up?
You can remove the Facebook applications from his profile if he leaves it logged into his account. I would also suggest running an Antispyware and AntiAdware program as well as clearing out your internet history.
Facebook is notorious for malware - it's specifically targeted, as the low average IQ of the users makes it easy to get them to download cr@p without realising they're doing it.
Definitely run a scan with malwarebytes Anti-malware:
