The CPU-Z and HWMonitor download pages have recently been compromised, with download links replaced with ones pointing to files infected by malware. If you've recently downloaded either of these apps from the CPUID site, you should double-check that the file is of the expected file naming style "hwmonitor_1.63.exe" or "cpu-z_2.19-en.exe" and not "HWiNFO_Monitor_Setup.exe" or some other format. It's also worth doing a virus scan, though Windows Defender is reported to have flagged the compromised versions of these files. The infected files were first spotted around nine hours ago, with an attacker seemingly having compromised the CPUID download site with these infected file links. However, as of right now, the correct links do appear to have returned to the page, so the apps should be safe to download again, although CPUID hasn't issued a statement yet regarding the issue. If you use either of these programs to monitor your gaming PC, your best bet is to keep using the versions you have and trust, or wait until CPUID has confirmed the situation.
