Whether you are a Windows or Mac user, you should always keep your operating system updated with the latest security patches which can prevent attack by nasty viruses and other malware by closing the security holes in your machine. It’s better to turn on the Automatic Updates in your computer so that whenever there is new security update available online, it gets downloaded and installed automatically.

Installing a Powerful Firewall:
Every computer requires a good firewall which is an application that blocks other programs installed on the machine from making unsafe connections to the outside world. Also it keeps monitoring all the incoming connection requests and prevents unauthorized access to your system from outside. Firewalls have logging feature and can keep track of whatever events happened in your system. It alerts you in case of any suspicious activity when a worm or virus tries to connect with your machine and also prevents them from downloading any malicious software to your system. It is explicitly useful to prevent Trojan horses which try to make outbound connections from your system and download malicious software which keeps replicating.
Handling E-Mails with Caution:
Another important tip to keep your machine free from viruses is exercising great caution with E-mails. You should never open e-mails from unknown senders or open attachments in mails which you can’t recognize. In many cases viruses spread through e-mail attachments and as soon as you open the attachment it gets downloaded into your system.
Configuring Strict Privacy Settings in Internet Browsers:
You should be aware that whatever information you provide about you in websites while browsing can be used for identity theft and other fraudulent purposes. They can also use this to install malicious software in your system. Hence you adjust your browser’s privacy settings to make sure all information is encrypted and also don’t allow unauthentic websites to store cookies in your system. Also turn on pop-up blockers by default since some pop-up windows from harmful websites can contain malicious code or links which can download viruses into your system. Allow pop-ups only from trusted websites which you use regularly.
Avoid Using Free Hot-spots in Public Places:
When you are travelling along with your laptop, you tend to use free Wi-Fi connections in the public places like bus stations, shopping malls, hotels etc. In such cases the security of your machine is compromised since it’s easy for any attacker to snoop on websites you browse and steal your identities. Also they can use this information to attack your system and install malicious software like viruses and Trojans to steal confidential data from you. Hence try to avoid using free Wi-Fi hotspots in public places.
