How often should I perform a full system scan with Avast antivirus?

We recommend running a full system scan with Avast antivirus at least once a week. This frequency ensures regular detection and removal of any potential threats that might have entered your system. Running a full scan allows Avast to thoroughly examine all files, applications, and documents on your computer, leaving no stone unturned. However, depending on your computer usage patterns, it may be necessary to perform scans more frequently. For instance, if you frequently download files from the internet or visit high-risk websites, it is advisable to increase the frequency to every few days or after each risky activity. Remember, regular system scans complement real-time protection and help keep your computer secure.
