Because of the huge malware attack these days, Antivirus software is designed to handle all kinds of malignant payloads attacking from both trusted and un-trusted sources. Antivirus software consists of different types of scan like full scan, quick scan and custom scan. Full scan [1] is performed to ensure that the computer is free from viruses.
It helps to scan files, local drive, folders on the system. Full scan can be performed on external devices like digital camera, USB drivers and many others. Quick scan is used to scan the most infected area in a computer. A quick scan checks only the common areas for viruses available in a computer. Scanned areas include common areas of the hard drive, including the temporary files, computer memory and the operating system directory. Basically quick scan take less than minutes to complete.
Full scan checks every folder available, and hence takes longer time to perform the scan. Depending on the hard drive and memory space a computer, it could take 40 minutes to several hours to accomplish a full scan. Custom scan as name implies allows the user to customize which files and folders are to be scanned. This scan is useful when the user likes to perform a scan for a particular folder, or if the user likes to scan an entire drive. Custom scan helps to remove unknown viruses, spyware, tracking cookies, potential threats and stealth programs, which can exploit and alter Windows system files.
For the performance study of different antivirus, parameters like full, custom and quick scan are performed on the basis of time. Logic formulae are an alternative to basic virus detection technique. Behavior based virus detection is used to overcome the issues related with traditional signature based virus identification. Signature based virus detection is explained with pros and cons. Viruses of the different types cannot be detected by single method. Signature scanning is concluded as the easy and economical method for detecting majority of current available viruses and it causes less impact on existing hardware and codes.
Network aware viruses like Melissa have proven that virus specified techniques are not sufficient enough to prevent infection by new viruses. The inherent backlog of post-infection generic methods and pre-infection heuristics make virus detection more powerful way to prevent and remove viruses.
Antivirus products that consist of hybrid approach are likely to evolve. The performance study of different antivirus is described in detail for computer in [5]. The classification is based on three groups ranks of antivirus i. According to the survey, no antivirus engine consistently holds the top place in each year across all testing organization. The performance and protection of antivirus is described in detail in [6,7] where different antivirus are compared based on scanning methods like on-demand and on-access malware scan ,website rating, malicious URL blocking, Phishing protection, Behavior based detection and vulnerability scan.

Some of the results seem mysterious, like all the times the no-AV configuration scored lower in many tests than it should be faster in. Is it possible that using the Wildfire as the system drive instead of the platter would have eliminated this behavior? In general, I hope there is a second part to this that does include SSD runs.
I would think any advantage AV products have vs. I stopped using AV products on my personal systems back in Norton back then was god-awful on a Pentium 4 systems, seemingly crushing the life out of a system. I might not use AV software, but I do put it on my family members' systems when it doesn't kill performance. In that respect these modern solutions seem much better. On my Pentium D I have to run McAfee when I'm gone for a good while or sleeping as my computer slows to a crawl during the scan.
Even bringing up the menus to stop the scan take way too long.
