How does anti-virus software work to protect computers from malware?
Anti-virus software work to protect computers from malware in a few ways. One way is by identifying and removing malware files that are already on a computer. Another way is by blocking new malware from being downloaded or installed onto a computer. Both of these actions are important in protecting a computer from malware.
First, anti-virus software will scan a computer for any files that match known malware signatures. If any such files are found, the anti-virus software will attempt to remove them. This can sometimes be difficult, as malware is often designed to make removal difficult. In some cases, the anti-virus software may quarantine the malware file instead of deleting it, in order to prevent it from being executed.
Second, anti-virus software will block any new malware from being downloaded or installed onto a computer. This is typically done by blocking access to websites known to host malware, as well as by scanning any files that are downloaded from the internet. In some cases, the anti-virus software may also scan email attachments for malware.
Both of these actions are important in protecting a computer from malware. By identifying and removing existing malware files, as well as by blocking new malware from being downloaded or installed, anti-virus software can help to keep a computer safe from harm.
