1. Antivirus software should be installed before Internet connection setup. Often viruses get in your computer before you download antivirus application or updates. Local network connection also should be disabled.
2. It is recommended to use antivirus that has real-time scanning functions. Such kind of antivirus software requires more system resources but provides more reliable protection. Viruses will be caught ‘on the fly’ and will not have time to penetrate the system.
3. Use ‘on-demand’ scanner regularly. Real time scanners monitor only confined number of ‘points’. But some viruses get in computer using security vulnerabilities that are not protected by ‘on-access’ scanner.
4. Don’t use more than one antivirus at the same time. Such situation can cause conflicts that will slow down your computer. Besides, solutions from different vendors may mistakenly take each other’s anti-virus databases as viruses.
5. Update your anti-virus databases as often as it possible. For example, ESET Nod32 bases are update three-five times per day.
