Working with a company that has 15 terminals. Almost all of them have gotten a program installed that shows no name, but immediately after a few office updates are removed from the system. To date, ESET NOD32 Version 4 has not been able to detect this - even with a bootable CD. AVG has not found it either. Malware Bytes Anti-Malware does not find it and it gets Error 732 when trying to update.
This is a big problem, as it sure seems like a virus, but I have yet to be able to identify or kill it with confidence. It seems to make browsing the net this side of impossible - with 2 or 3 searces, the user must reboot. And slows computer.
