Single-host dual-OS anti-virus skills

Many people have installed dual systems, and the file security of multiple systems must be taken into account under the dual system. Here we provide two practical tips for using anti-virus software in two dual systems for your reference.

I. Dual-System Virus Database Upgrade Method

We know that many people now have dual-systems to facilitate computer installation. For example, I have installed Windows 98 + XP. However, For Norton Anti-virus software, it has two versions For Windows 98/XP, unlike Kingsoft's version installed in Windows XP. In this way, the virus library is upgraded in Windows XP, and the virus library needs to be upgraded again in Windows 98. Every upgrade will waste time and money. I found a way to upgrade the dual-system Norton virus database at the same time. In most cases, we only upgrade the virus database file, so we only need to copy the upgraded virus database to another system. For example, if the location of the Norton virus database (in the default installation path) is . Open the VirusDefs folder and we can see that the recently upgraded virus database, such as 20040726.007, is the virus database in July 26. We can copy the entire VirusDefs folder to the same directory of another system, after restarting the computer and entering another operating system, we can see that the Norton virus database has been upgraded, and other anti-virus software has been upgraded similarly.

2. Upgrade Kingsoft drug overlord without restarting the computer

After the virus database is upgraded, the virus database must be restarted. However, if we run update.exe directly on another system without Kingsoft virus, we can upgrade the virus database to the latest virus database without restarting the computer. That is to say, for this type of anti-virus software, you can directly upgrade the virus database in another system.
