Antivirus software consists of an array of programs created to scan your PC’s hard drive for viruses, Trojans, and all types of malware. Again, it makes it difficult for such harmful irritants to be downloaded from the online space straight to the computer.
The software usually functions in a protective mode by deleting or quarantining the infectious files. Computer viruses can cause a severe threat to computers, and you must realize that not all antivirus software is fool-proof — or even without cons. The fact remains that the benefits of having an antivirus installed on your PC far outweigh the consequence of malware; antivirus programs could prevent access to legitimate applications. If you find it difficult running a file correctly, check your antivirus running in the background.
Pros: Malware Prevention
Some antivirus software will not scan the computer and delete any infection files.

Furthermore, they prevent Active X-based spyware; restrict access to potentially dangerous sites and many more. The AVG review will give you a piece of adequate information about this.
