I have a friend who recently stung by a virus and it has totally messed up his computer. Windows explorer doesn't work properly, his personal folders keep getting hidden, he is sending e-mails with virus attachments and a hackers website has become his homepage!
This has totally freaked me out as I have always heard about viruses, but to actually see the damage one can do is quite a shock.
I have therefore decided to invest in an anti-virus software. I do not know much about these so I was wondering if there were any recommendations as to which is the best one to get. Any insight greatly appreciated.
