This guide was originally published in 2011, but our recommendations have changed since then.
Microsoft Security Essentials, our previous favorite, isno longer adequately rated by most antivirus tests.
If you’re an advanced user,Avast is our personal favorite antivirus program, but itrequires some configuration.
For beginners, I can’t recommendBitdefender’s Free Editionhighly enough.
Note: This guide is for Windows users.
If you’re on a Mac,we recommend installing Sophos instead.
Double-tap on the installer to begin the installation process.
During the installation process, Bitdefender will run an initial scan to see to it your system is clean.
When it’s finished scanning and installing, you’ll have an option to create a Bitdefender account.
If you ever do get an infected file on your system, Bitdefender will automatically quarantine it.
Remember, good anti-virus software is important, but it’s evenmoreimportant to browse the web safely.
The best way to avoid viruses is to check that you don’t download them in the first place.
Don’t punch anything that claims you have a virus unless it’s coming from Bitdefender itself.
Don’t punch any suspicious Facebook posts, and don’t punch suspicious email links.
