Bitdefender excels at malware detection and protection, but if it appears to stop scanning your PC for threats or Bitdefender Central refuses to show up, the antivirus can’t do its job properly.
If your Bitdefender antivirus isn’t working, it can lead to dangerous software sneaking its way onto your device. Nobody wants ransomware, spyware or even adware lurking around, so getting your antivirus working again should be a priority.
The good news is fixing Bitdefender is simple, as sometimes all it takes is an update. This article will help you get Bitdefender working again, along with a way to test if the antivirus is working.

Update your antivirus
Is your Bitdefender antivirus up to date? If it isn’t, you’ll want to update it.
Antivirus software these days are efficient enough to stay updated and notify users if they require a refresh. You will usually get a notification about your software needing an update. While it can be a pain to click “Update” and restart your device for the update to take effect, it’s certainly worth doing.
While protection programs are designed to detect malware signatures automatically and use behaviour-based detection to thwart any malicious software it sniffs out, even these systems need an update from time to time. This makes sure that any new threats that have surfaced can’t get by any older systems set in place as hackers continue to find ways to sneak past a system’s protection.
All the best protection software will notify you that an update is needed if you open the app. Otherwise, you can update that software manually.
You can update Bitdefender by right-clicking the Bitdefender icon in the taskbar and selecting Update Now. It’s as easy as that.

Test your antivirus
If Bitdefender can’t detect or protect you from the simplest of malware, what’s the point in installing it? Well, that’s why we review different software to make sure it’s all up to scratch, but there’s another way to test if your security is working: get malware.
It’s never something you want to have on your device, but the EICAR test file will put your worries at ease. It was developed by the European Institute for Computer Antivirus Research (EICAR) to test products. And before you ask, “But isn’t using test malware still risky?” No. Not in the EICAR test file’s case.
The EICAR test file isn’t actual malware. It mimics the behaviour of malware that the security software can pick up. Providers acknowledge this as a general standard for testing, so your antivirus software will detect it like any other malware once it is detected.

So, to make sure your protection is working, try to download the EICAR test file via the website and see if Bitdefender detects it. If it doesn’t, then you’ll want to try other means.
Upgrade your antivirus software
More likely than not, the protection software on your device is the program that came with your device when you purchased it. You may have forgotten it was there or installed free software a while back. They may not be up to standard anymore, or your device may not click with them.
If that’s the case, consider upgrading your Bitdefender subscription package. Bitdefender offers several different security solutions for different budgets, including Bitdefender Antivirus Plus for one Windows device that provides real-time protection against viruses and malware, prevents phishing scams while online, and a VPN with a 200MB per day limit.
There’s also the Bitdefender Premium Security package that comes with the software’s Total Security platform, which includes threat detection, ransomware protection, and more; an unlimited VPN; and a password manager.
