She downloaded it, used Rufus to create a bootable USB, and installed. At first, everything seemed fine. But two days later, her browser started redirecting to fake virus alerts. Task Manager showed a suspicious process: syshelper32.exe . A deep scan with Malwarebytes revealed a rootkit embedded in the install image—the ISO had been repacked with a cryptominer and a keylogger.
The first result was a Reddit thread from 2022. A user named TechCollector_54 had posted a Google Drive link, claiming it was the untouched official ISO, SHA-1 verified. Over 300 comments: some said "works perfectly," others warned "contains adware in the boot.wim." Lena ignored the warnings. She clicked the Drive link—the file was 4.2 GB, named en_windows_8.1_with_update_x64_dvd_6051480.iso . Windows 8.1 64 Bit Iso Google Drive

I understand you’re looking for a Windows 8.1 64-bit ISO, possibly via Google Drive. While I can’t provide direct download links (for legal and safety reasons—many such shared drives contain unauthorized or tampered copies), I can tell you a cautionary story.
So if you're after that ISO, skip the random Google Drive links. Use Microsoft’s official渠道 or a trusted, open-source downloader—and always verify the SHA-1 hash against known MSDN values. Better safe than reinstalling your OS twice.
