You need to have 360TotalSecurity installed to enable the trojan scan. So... kind of useless.I've recently started using Qihoo's 360 Zip. It does a virus scan of any archive you open, and it is free of ads.
I don't know if it has changed, but in the past when I downloaded it from the above link, it installed in Russian. I installed the English language version from the Tool Box section of 360 Total Security.Download 360 Total Security for Windows. Protect and optimize your computer with award-winning free antivirus.
