The perfect antivirus software is the one that works best on your system, has the features you want, and is easy for you to use. Since each system is unique, if you’re looking for new antivirus software, you want to evaluate several products to find the one best suited to your PC and your level of experience. Of course, you may wish to remain with only qualified, reputable antivirus products that have obtained certification in the 3 major certificate authorities: Checkmark, ICSALabs, and VB100 which have performed well on the rigorous tests conducted by AV-Test. org.
While generally speaking, the paid antivirus provides more features that could provide complete security, those making an a la carte security solution could fare better with one of these free standalone antivirus scanners. For specific recommendations on best of class in their respective classes, see the following:
Can you require the antivirus and also an anti-spyware scanner?
It depends. Some antivirus products, especially McAfee VirusScan, include stellar spyware protection, but many others do not. If you are experiencing ongoing issues with spyware, then you might want to consider including a dedicated spyware scanner to the mix.
Do we need to uninstall existing antivirus program before installing a new one?
If you are switching to a different antivirus product, you will need to uninstall the antivirus scanner. After uninstalling, you need to reboot your PC before installing the new scanner.
If you are simply upgrading the existing antivirus software to a newer version of the same solution, there is absolutely no need to uninstall the old version. However, if the new version is a few versions newer than the old, then you might want to uninstall the old version before installing the new. Again, anytime you uninstall a present antivirus product, make certain to reboot your computer prior to installing the newest scanner.
Could two antivirus scanners be run on precisely the specific same system at precisely the specific same sime?
Previously, It was not a terrific idea to run two antivirus scanners simultaneously. However, if only one of these scanners has real-time security enabled and the second scanner is used only to manually scan files that are chosen, they may possibly reopen peacefully. Some computer applications are designed to be the next scanner on a system. In a few cases, an antivirus scanner will not install if it detects another antivirus scanner installed on the system.
Why can your scanner detect a virus when another does not?
Antivirus is largely signature-based. The signatures are produced by the individual vendors and are exceptional for their products or the products using those particular scanning engines. Hence 1 seller might have added detection (i.e. a bit) to get a particular malware while another vendor may not have. As a result of this, it is oftentimes better to run two unique antivirus applications.
