Can You Have 2 Antivirus Programs on Your Computer
Do y'all accept an antivirus installed and running on your system? In this twenty-four hour period and age when free antiviruses can tiptop the leaderboards on virus detection tests, at that place'south always a solid and efficient security solution you tin can download without spending a penny. This may become people thinking about downloading multiple antiviruses. After all, the more than you download, the safer your computer will be, correct?
Unfortunately, the concept of "the more the merrier" doesn't piece of work and then well with antivirus! In fact. the more than antivirus you install on your system, the messier it can go. Information technology may audio weird – later all, it sounds better on paper to have multiple layers of security – but at that place are reasons why you don't want to install multiple antivirus software at the same time.
Functioning Issues
When antiviruses piece of work on protecting your computer, they demand to apply computer resources in order to perform their job. Non only that, they have to continue tabs on every potential entry point that a virus can use on your reckoner. This can range from plugging in a USB stick to downloading a file from the Internet. Equally such, it needs to perform what'south chosen "real-fourth dimension scanning" which monitors any deportment being performed on files and checks to see if it's a virus performing said action.
This is fine when you've installed just the one antivirus, every bit information technology has enough "room" to settle in and do its job. The more antivirus programs you add, however, the more memory gets taken up by antiviruses scanning every potential intrusion point. What this leads to is a computer which won't take enough memory bachelor to perform other tasks, so you'll notice it running slower than before.
Fighting Over Files
Even worse, you'll find that they'll often clash with one another when protecting your system. The goal of an antivirus is to piece of work every bit quick every bit possible to isolate a virus when information technology infects your PC. This means that you're going to accept two or more highly vigilant antiviruses that will exist monitoring everything you practice at exactly the same time. While information technology initially sounds good, the results volition exist anything merely!
Let'south say you download a file from the Internet. A skillful antivirus will choice up on this action and immediately perform a browse on said folder to brand certain it's not infected. Unfortunately, if you've downloaded several practiced antiviruses, it means they'll all clamour over one some other to scan the file all at once. Y'all may detect the file is deadlocked where every antivirus is trying to claim ownership of information technology, and you'll probably observe a system operation decrease while this happens.
When a file does turn out to be a virus, multiple antiviruses tin terminate upwards making things more trouble than need be. Both of them will want to remove and delete the virus under their own terms, which will cause both of them to ask you if y'all desire to quarantine them. Unfortunately, they'll only actually accept a quarantine if they're the ones doing the quarantining. If y'all let one to quarantine the virus and deny the other one, that second antivirus may pick up on the file in the get-go antivirus' quarantine and constantly alert you lot of a virus threat, despite the fact that information technology's safely stored away!
Accusing One Some other
The worst effect of multiple antiviruses working in tandem is that they won't trust one another. When an antivirus does its job, it assumes it'due south the only i installed. Therefore, if they detect a second antivirus scanning through files, they'll presume information technology's really a virus. At best, you'll be bombarded with false virus alerts when the antiviruses spot one another. At worst, they may brainstorm trying to delete each other's files which will atomic number 82 to system instability and important files existence corrupted.
What About Scanners?
Throughout this article we've been focusing entirely on antivirus programs – the ones that piece of work in the background on a deep level in an operating system. Yous may take downloaded anti-malware and anti-spyware scanners to assistance protect your PC. These are different, as they aren't always scanning for threats merely can be used to do a single sweeping browse on a PC when you lot ask it to. Will these scanners cause problem with an agile antivirus?
To answer this, information technology depends on what you're using the scanner for. Some scanners have their ain existent-time scanning selection which will probably conflict with an antivirus' own. If y'all disable these real-fourth dimension features and perform a simple scan with it, information technology probably won't conflict. Ideally, you can tell your antivirus to exclude the scanner from its own scans, and then it'll leave your scanner alone. Even then, still, you may observe a performance drop equally both of the software browse at the same time.
If you're interested in using an antivirus and a scanner at the same fourth dimension and want to acquire the ramifications, expect on the website of your favourite scanner software for help. For example, Malwarebytes has a listing of compatible antiviruses (PDF) while Spybot discusses how to make information technology work hand-in-hand with an antivirus.
All for One
When researching antivirus software, you lot may feel tempted to download and run multiple programs to boost your security. The truth is, this is far from ideal! Pick one antivirus yous gel with the most and utilize that ane alone. If you desire to secure your figurer as much as possible, read antivirus reviews and pick the 1 that performs best.
What does your computer's security expect like? Practice you lot make use of an active antivirus and scanners? Do yous use your Os's built-in antivirus solution? Or are you using an OS that doesn't need one? Let us know beneath.
