Other antivirus products take much longer to be fully ready for scans: 62 seconds for Norton, 93 seconds for Kaspersky and 500 seconds for McAfee. Low installation time – it takes only 5 seconds for the Webroot antivirus to be up and running.The main reason for this is that Webroot virus definition databases are cloud-based and not saved locally on the installation disk drive. Compare this number with about 770MB for Kaspersky, 730MB for Norton Antivirus and 300MB for McAfee. Low hard disk space usage – Webroot software only needs about 2MB of hard disk for installation.Low computer RAM usage – many similar products in the market take way more than just about 5MB of RAM which is the amount taken by Webroot SecureAnywhere Antivirus in the system idle time.This antivirus is also capable of protecting users against spyware (programs which collect and steal sensitive information), and rootkits. It also stops harmful and infected websites while users surf web. In addition to being an antivirus program, Webroot SecureAnywhere is also an antimalware meaning that it could remove worms and malicious software which infect systems.
