1, according to the analysis of the web page you provided, you downloaded not an e-book, but a tool to support e-book reading.

I checked it for you. This website belongs to an unknown security website, and the software it downloaded may indeed have Trojan virus.

I suggest you download a computer housekeeper from official website, Tencent's computer housekeeper.

4. Right-click the EXE installation package, scan the virus (computer housekeeper) to see if it carries a virus. If there is a virus, clean it up according to the instructions of the computer housekeeper. If the test result is non-toxic, you can rest assured to continue using it.

5. If there is virus in the test, you can open the computer housekeeper-software management-software warehouse-search reading in the upper right corner and download other reading tools again.

If you have any other questions, please come to the computer housekeeper enterprise platform again and we will try our best to answer them for you.
