When logging in to the website, read the browser address bar and check that you are logging into localbitcoins.com and not a phishing domain.

Do not install third party software, pirated software or browser addons you cannot trust 100%. This greatly reduces the risk of getting Bitcoin stealing malware infection on the computer.
