Yesterday, I visited my elderly neighbor and his 21” iMac, 3.06, C2D, 4 GB RAM, 10.6.8…

What my neighbor feared was a virus, was only a plethora of spam. He will be on travel for the next 10 days, so there is a bit of time before my next visit.

1. While he does not have a virus, he does have MacKeeper installed (and the genesis of his spam?). As I understand it, it is malware and should be removed. To wit, there seem to be many opinions on the web re the best technique for doing so. But from my trusted colleagues who have actually done so, what do you recommend?

2. He uses Yahoo (POP) -> Apple Mail for his email. Assuming that it is easily done, can I/should I convert his POP to IMAP? If so, how?

2. On my next visit, I hope to update his operating system (he hasn’t updated anything in over 3 years). It may be worth noting that he mainly uses his computer for email and surfing. What OS do you recommend?

TIA
