I got a call from a local library that used Millenium ILS and Sierra ILS and they stated that they are unable to print reports again. The last time it happened, it was due to the Adware on the computer so I grabbed a copy of Malwarebytes and the Barracuda Malware Removal Tool and headed out the door.
Malwarebytes was already on the PC from my visit from 30 days ago so I did an update to the definitions and let it run. To my amazement, Malwarebytes found nothing so I went back to my screen capture of the Control Panel from my last visit to see what is added or removed and noticed that OneUpdater by VOMPT Limited and SSOption by Deep Repeat Use were installed to the computer the very next day after I provided a service call.
It seems that the students who got permission to work in the library were using the computer that is dedicated to library operations for streaming movies as the computers in the OPAC (online public access catalog) area are configured to restrict such activities by the Barracuda Web Filters.
If you found one or both installed on the computer, please note that you may have to remove them manually through the Control Panel uninstall function. Once that is done, continually updating Malwarebytes daily so that it can catch any hidden traces that may be left behind.
