1. Switch to another antivirus software

Before we jump to the other solutions, we’d like to make a warm recommendation that might come in as useful when you encounter problems with your current antivirus.

Namely, we advise you to switch to another antivirus software that is maintained better by its developers and that has other useful features.

While Avira is a great choice for those who prefer a free antivirus, there are better premium apps out there that include even more security-related tools.

In addition to protecting your PC from malware, ransomware, and other harmful files, the software will also secure your banking transactions, and protect your webcam and microphone from being hijacked.
