Computer viruses are computer applications that can multiply themselves and infect workstations.
Their devastating effect is increased if one of the infected computers is connected to a network. The presence of viruses can be detected only when they affect the computer's performance.
Unlike traditional antivirus applications, removal tools are targeted at specific malicious programs and users will need to scan the suspicious folders manually, so that the virus can be identified, located, quarantined or deleted.
Viruses typically get on computers when users unknowingly download malware components, access infected websites or connect infected removable media to the PC.
