The short answer is yes it probably is running a bit slower while the anti virus program is running but not as slow as a system infected with a virus. If you are worried about performance schedule the anti virus program to run at a time when the system is not in use ie. overnight and let it run.
I assume you are talking about a virus scan. I don't think it is important. You can scan your entire computer ONCE after you install your antivirus; after that, perhaps every few months. Modern antivirus programs will automatically scan individual files when you try to open them; this renders a scan of the entire computer superfluous.You DO have to make sure that 1) your antivirus is still active, including the function described above (to scan every file as you open it), and 2) that it gets updated regularly.
When it comes to protecting your computer from all of the most serious virus threats that are circulating the internet, McAfee Antivirus has long been considered to be one of the most reputable antivirus programs in the industry. Unlike Norton’s antivirus software, McAfee Antivirus does use up much of your computer’s resources and is very easy to uninstall if your decide to try out a different virus protection software package in the future. McAfee Antivirus provides computers with daily updates on all of the latest malicious codes that have been discovered by computer security professionals so that you can be sure that your computer is completely protected. Here is an inside look at what you need to know about McAfee Antivirus. While pretty much everyone knows that they can rely upon McAfee Antivirus for comprehensive virus protection, it is crucial that computer owners know how to use this software properly. If McAfee Antivirus is not configured to automatically download new virus definition and other pertinent information, a computer owner may rapidly discover that his or her virus protection software is powerless to protect them from the newest virus threats to emerge on the internet. At the same time, many computer users make the mistake of ignoring certain prompts from McAfee Antivirus that require an user to take some particular action. For example, this program will sometimes require an individual to restart their computer before an update can be put into place, and failing to restart the computer can leave a person vulnerable to certain viruses. One of the most popular features of McAfee Antivirus is that it can be configured to run quietly in the background of your computer without intruding with a computer users daily computing. Some virus protection programs like Norton AntiVirus seem to constantly be interrupting a person’s activities with notifications of a system scan or the discovery of some minor threat. As anyone who has worked with Norton security software programs before can attest, the system scans performed by this line of software consume an enormous amount of a computer’s resources and can be very inconvenient. McAfee products, on the other hand, run so quietly and unobtrusively that you will sometimes wonder if they are even running at all.
A good version of micro antivirus is the most current one. With new viruses coming out on the daily, your best advice is to keep your antivirus as up to date as possible.
Antivirus software can prevent most, but not all virus infections on a computer. This is because antivirus programs have one major disadvantage: they detect viruses using a large database of the signatures of every known virus. Because new viruses come out daily or even hourly, antivirus companies are falling behind malware writers. One report stated that the Symantec antivirus company had to create 36 new signatures every 7 seconds in order to keep up with malware writers.
