Steps that you can and should do to protect yourself while browsing the internet:
Step 1: Never run a computer on the internet without an anti-virus software, which is kept up to date and scanned daily.
Step 2: Just anti-virus is NOT enough to catch all breaches to your computer. You need anti-malware also to catch the things, that anti-virus does not catch.
Step 3: Never open email attachments from people that you do not know! There may be a virus attached to it, and it could access your personal information.
Step 4: Always have strong passwords, at least with seven letters, and numbers, and special characters.
Step 5: Never download from a site that you do not know whether it is safe or not!
