Protect personal computer from hackers, viruses and malicious programs

Install a personal firewall and a reputable anti-virus program to protect personal computer from virus attacks or malicious programs.
Ensure that the anti-virus program is updated and runs at all times.
Always keep the operating system and the web browser updated with the latest security patches, in order to protect against weaknesses or vulnerabilities.
Always check with an updated anti-virus program when downloading a program or opening an attachment to ensure that it does not contain any virus.
Install updated scanner software to detect and eliminate malicious programs capable of capturing personal or financial information online.
Never download any file or software from sites or sources, which are not familiar or hyperlinks sent by strangers. Opening such files could expose the system to a computer virus that could hijack personal information, including password or PIN.
