I have just been fixing a friend's laptop that had XP Internet Security 2011 on it. I seem to have managed to remove it easily by going back to a System Restore point a couple of days previous but I would really like to know how it got there so I can advise her for future. The friend in question is typical of a number of more mature ladies I help out. She basically uses her laptop for email and limited web browsing and is very cautious and wary of anything unfamiliar. The laptop has automatic updates enabled, an up-to-date Microsoft Security Essentials and Windows Firewall.
She says that she hasn't loaded any software for weeks or been asked to load or update anything that it could have piggy-backed on. There is certainly nothing recent under Program Files and the only recent System Restore points are from automatic updates. I have checked her recent emails and there are none with attachments. Some have links, usually to jokes of some sort, but I have checked her browser history and she has only gone to about 20 sites in the last week and all of them innocuous and not from the email links.
Can anybody please explain how these nasty bits of software typically get on to machines or anything else I can check or do before handing it back.
