A hacker might be downloading files from your computer. One way to check if someone is downloading files is to look at your Internet connection information. If there is a lot of activity on your connection, yet you have not initiated any file downloads or web page requests, it could mean someone is breaking into your system. While these programs are not necessarily sending information over the Internet, a hacker could break into your computer, steal these files and use them to commit fraud. You may want to consider obtaining an encryption key for your email.
Encryption software is available from a number of popular software companies.
Conclusion Hacking is not merely a hobby for young computer nerds looking for fun. There are some hackers that are dedicated criminals and terrorists. With more people using the Internet for purchasing goods and services, there are more opportunities for criminals to steal from you. Even simple protection measures can help defend yourself and your computer from these criminals. Nobody is exactly sure how much damage hackers cause each year.
