Viruses on Android devices are a real threat, especially if you install applications from unverified sources or often connect to public Wi-Fi networks. Scanning a smartphone through a computer using Kaspersky Internet Security (or Kaspersky Total Security) allows you to identify hidden threats that may go unnoticed during a standard scan on the phone itself. This method is effective for several reasons:
Firstly, PC antivirus has more powerful analysis algorithms and up-to-date signature databases than mobile versions. Secondly, scanning through a computer eliminates the risk of malware being blocked on the device (some viruses disguise themselves as system processes and prevent the antivirus from starting on the smartphone). In this article we will analyze step-by-step process of connecting Android to a PCsettings Kaspersky for scanning mobile devices and interpreting scan results.
Why scanning through a PC is more effective than on a smartphone
Mobile antiviruses are limited by resources devices: they work in the background, save battery power and do not always have access to deep system files. Kaspersky on a computer is free of these restrictions. Here are the key advantages:
- ๐ Deep scanning: The PC version scans not only installed APK files, but also system partitions, application caches, as well as hidden folders where viruses are often disguised as legitimate files.
- ๐ Current databases: Signature updates are arriving on the desktop version more often than on mobile, which is critical for detecting new threats (for example, Trojans
Bankeror spywarePegasus). - ๐ก๏ธ Threat isolation: When a virus is detected Kaspersky on a PC it can immediately block suspicious files, while mobile antivirus sometimes requires manual removal.
- ๐ Connection analysis: The desktop version checks not only files, but also the network activity of the smartphone (for example, suspicious outgoing connections to IP addresses associated with botnets).
In addition, scanning via PC allows bypass). manufacturer restrictionsthat block access to system folders on some models (for example, Xiaomi with MIUI or Samsung with One UI This is especially important for devices with root access or custom firmware, where viruses can hide in non-standard directories.
โ ๏ธ Attention: If your smartphone was previously infected, some viruses (for example,TriadaorNotCompatible) can block the connection to a PC via USB. In this case, use the modeFastbootor boot the device inSafe Modebefore. scanning.
