I suspect there are some red-faced programmers at BitDefender. The company released an update to its popular BitDefender antivirus software for Windows. The 32-bit version seemed to operate properly but the 64-bit version of BitDefender falsely claimed that many files were infected with viruses, including Windows files from Microsoft and even BitDefender files included as part of the BitDefender antivirus software!
Some BitDefender users are now unable to boot their PCs.
The company acknowledged the issue in a note explaining the problem. "Due to a recent update it is possible that BitDefender detects several Windows and BitDefender files as infected with Trojan.FakeAlert.5."
