Install anti-spyware and anti-malware software.

Malware and spyware can do as much damage as viruses. Most people simply purchase anti-virus software with spyware and malware capabilities, but no single programme can find and remove everything. A multilevel security approach is necessary to allow a more focused attack against those threats.

Perform a daily full system scan.

Viruses, spyware, and malware are continuously evolving. This scan can be done by anti-virus, anti-spyware, and anti-malware software to remove malicious files from your system and avoid further damage.

Create a regular system backup.
