Panda users had a bad hair day on Wednesday, after the Spanish security software firm released an update that classified components of its own technology as malign.

As a result, enterprise PCs running the anti-virus software tied themselves in something of a knot, leaving some systems either unstable or unable to access the internet. A Panda spokesman confirmed the problem while advising that the issue was well in hand.

"A bad update was published temporarily today [Wednesday] that resulted in some system files being detected by the Panda engine, a replacement update was promptly published removing the error and restoring the wrongly quarantined files," a Panda representative told El Reg.

"At present we recommend NOT rebooting systems. This will allow us to update the system with the amended update. This update will also restore files previously detected," he added.

An official advisory on the problem says that the issue was limited to Panda Cloud Office Protection, Retail 2015 products and Panda Free AV. Users are strongly advised not to restart their computer until a fix is available.

El Reg heard about the Panda slip-up via a tip from reader Austin, who ought to be excused claiming overtime on the back of the problem.

"Dozens of installs of Panda Antivirus across multiple sites all just detected components of itself as a virus, simultaneously," Austin explained. "Perhaps 60 in total across five sites, out of an installed base of around 300."

"If you let it disinfect 'the problem' with a reboot, you have no network access post-reboot."

"Files we've seen 'detected' include psanmodrep.dll and alertsmanager.dll – both key components of Panda Antivirus itself," he added.

Users of Panda's anti-virus took to Twitter to air their woes.

Worst antivirus every. Panda has today wiped files from system32 leaving rebooted computers bricked. Do not reboot, update Panda.

False positives involving anti-virus updates have affected all vendors from time to time.

The consequent problems are at their worst when Windows operating system files are falsely classified as potentially malign and quarantined, resulting in unusable Windows systems. Panda's auto-immune screw-up would have caused comparable problems

That's hard! ;)

Very critical because updates like this could not determine the usability of your computer, + advisories which may also not cope up immediately/easily by users for this erroneous problem. The Reboot Problem will be another dangerous side because other users might attempted it already as a very common way if there's something wrong on a computer and thought it will solve upon boot up. ;)
