Are you sure she didn't allow him access to her laptop with Remote Desktop?
I've had scammers try to convince me to grant them access to my computer that way so they could "fix" an imaginary problem. Their social engineering tricks can be very convincing to unwary or non-technical users and are usually necessary to gain that level of access (unless the laptop has no firewall or other protections active, I suppose).
In any case, to be prudent you should probably change all your passwords ASAP if you haven't already done so and do a deep scan for malware/Trojans (with a program like Spybot Search & Destroy, which is free). If strange or suspicious problems begin to arise then it'd probably be easiest to take it to a trustworthy IT professional and have them erase your HD and do a clean install of your OS.
And if you do any banking with or have any private/personal information stored on the computer that was compromised then you'd better keep a close eye on your credit report for a while (or seriously consider signing up for a credit monitoring/identity theft prevention service).
I also recommend Blur, a very handy service that allows you to use "masked" emails, phone numbers, and credit cards for online transactions or member logins (I have no affiliation with the company that offers it). It prevents hackers, telemarketers and other scammers (or online merchants with lax security) from obtaining your real contact info or credit card number. It can also create and manage secure passwords for you.
Email masking works by generating a random email address that forwards to your real one so you can use it once and delete it (or keep using it as long as you like). Phone number masking assigns you a disposable phone number that forwards calls to your real number so you can be contacted via phone without giving out your (real) phone number.
Credit card masking allows you to create a one-time use card number for online purchases; you transfer just enough money to complete a transaction and then discard the number (it functions more like a single-use prepaid debit card). Anyone who obtains that number after the transaction is complete will be unable to withdraw any more money from it, drain your bank account, or ruin your credit. The basic version is free and the masked cards and phone numbers are part of the "Premium" version which costs $2 to $5/month. There are many professional and user-submitted reviews available online to help you decide if it fits your needs and if the Premium version is worth the cost.
