Once you know an email is from a trusted sender, hover your mouse over the attachment to see the file extension. This is the last three or four letters that appear after the period in a file name that lets your computer know which application can open the file. Email attachments that contain images, videos, and audio files are generally considered to be the safest to open.
However, it is important to note that, even if an image looks safe, it could be another type of file in disguise.

Copying from a file is not typically saved on a windows system unless you have enabled logging or auditing. Yeah thats what i said; but I mean what about encase and helix big forensic technologies? EnCase and Helix can help you retrieve all the information you have on a disk, but they can't make that information from nothing.
Sorry to disappoint you. I used to run a forensic team, and while there are a lot of good pieces of info you can grab, with dating windows logging you are very limited in finding out what someone has done with a file if they copied it onto a USB stick.
You can hunt down command history, but it is limited. Seriously, this info is just not stored anywhere by default. This is why we encourage people to enable logging and auditing. Make sure you have a good antivirus application. Static antivirus scanners are helpful, but make sure you have something that proactively scans your system and is always alert.
Blake also suggests you have an antivirus and anti-malware application on your machine. Sometimes one application can catch something that the other one won't. We've discussed the difference between antivirus and anti-malware before.
If you need a good antivirus app for Windows, we recommend Avast! Free Antivirus. Make sure you know your security holes. There are some weak points that almost everyone is vulnerable to , so get familiar with them.
Additionally, using weak passwords and browsing insecure web sites are all things that can make gaining access to your machine easy.

You also want to protect your machine from unwanted physical access.
You might think you can leave your laptop open for a few minutes while you run to the bathroom, but it only takes a few seconds to unload a malware payload and even less to grab your machine and run. Always keep your computer physically secure and in your sight line. Keep your OS locked with a strong password if you must leave your machine unattended, but only do so in an environment where someone can't steal your computer.
Backup your machine regularly so you don't lose all of your data if your machine is stolen. Encrypt your hard drive if you're able. What are things that a hacker can do to me? How will I know if I've been hacked? What can I do about computer hackers and predators?
