What you mean with "overall safety & security"?
He uses a antivir-programm and set a password for the wallet. What further measures are necessary? Some Anti-Malware programm?
I wrote a thread long time ago about it.
https://bitcointalk.org/index.php?topic=203876.0If you want to be safe,you have to take care of several things.
1. If you are using Windows, Keep your software (MS Office, Adobe PDF,Java,Flash etc ) and OS updated.
2. Don't download things from unreliable sources, If you do, make sure to scan them on

3. Avoid Spam emails with Pdf/word file attachments.
4. Secure your WIFI and modem/router.
5. Avoid random person's pendrives.
I know a case where a guy contacted a buyer on localbitcoins and told him that he wants to sell cheap coins for cash, He created escrow on Localbitcoins, then he went to buyers house with his pendrive and said his password is written in a notepad file, then logged on localbitcoins and did transaction, took cash and left. Few hours later buyers account was empty and he lost other coins too.
What that hacker did? He probably used usb autorun function or binded exe file with txt and changed extension.
