- If a website tells you you have to install a toolbar to use it leave the site
- Don't download something you don't know what is.
- Don't install something just because it popped up and told you to.
- If you suddenly get an email or message from a friend that has an attachment that you were not expecting don't open it until you check with your friend to make sure they sent it.
- I suggest using either Google Chrome or FireFox for your browser instead of Internet Explorer they are much safer
- When you do install programs watch for any check boxes or anything that mentions it installing toolbars or addons and uncheck these boxes before installing the program
If you think your computer already has malware I would highly suggest getting Malware Bytes to remove it you can pick it up Here
