A computer is a powerful collection of systems that are capable of doing lots of activities. But whenever these systems are invaded by viruses and malware, the computer will malfunction and it could lose all its data or stop booting completely. Consequently, computer viruses must be avoided if you want your computer system to function properly.
To avoid computer viruses and enjoy using your computer system for a long time, these are the things you need to do:
Install professional and quality antivirus software
The first line of defense against invasion by computer viruses is the installation of high-quality antivirus software on your computer system. There are different types of antivirus software; however, some of them do not provide enough protection for your system; hence, your computer is still at risk of being corrupted by a virus. You should endeavor to scan your computer system once in a while depending on your level of usage.
Some of the high-quality antivirus software that can reduce the vulnerabilities of your computer system to different viruses are McAfee Antivirus Plus, Avast Pro Antivirus, Webroot SecureAnywhere Antivirus, Symantec Norton Antivirus Basic, Bitdefender Antivirus Plus and Kaspersky Anti-Virus.
Update the antivirus on your computer regularly
Trojan horses, worms, and viruses are produced from time to time; hence, your computer is at risk of newer versions of these harmful elements daily. When using outdated software, these viruses, Trojan horses and worms may be able to get into your computer system. Therefore, you should update the antivirus on your computer system regularly.
Be careful when opening new files and email attachments
Lots of computer viruses are sent as new files and email attachments that people open easily without suspicion. Take caution by being certain of the source of an email attachment or new file before opening them, so as to avoid computer viruses. Even after knowing the source, make sure you scan every email attachment and new file before opening them.
Maximize the security settings of your browser
Each browser comes with security settings that each user can adjust, so maximize the security settings of your browser. These settings may include blocking of unwanted ads, blocking of certain suspicious websites and so on. You also need to update your browsers whenever there are new versions.
Scan all external media
Flash drives, external hard disk, and other external media are known to be highly vulnerable to viruses; thus, you must scan them whenever you want to load them. Scanning will only take few minutes, so you have no excuse for not scanning external media.
Run sandbox to test new software
Whenever you need to run new software on your computer system, do not hesitate to use the sandbox to test its behaviors. If your new software does not act well, uninstall it to ensure your system is free of viruses and Trojan horses.
Beware of suspicious websites
While surfing the internet, you might come across some sites that you suspect to have viruses. In such case, do not let your curiosity get the better of you; simply avoid opening such websites.
