Microsoft Office crashes

[0xDiddi]

My dad and my friend have a problem where after like 5 minutes their Microsoft office would stop responding and eventually crash.

The problem affects all MS office programs, but (as observed so far) no other applications.

They both couldn't find anything on that issue online and as their specs are quite different, none of us has a clue as to what the cause might be.

 

My dads' specs:

Spoiler

CPU: AMD Athlon II X2 260

OS: Windows 10 Pro (x64)

OS Version: 1709

OS Build: 16299.192

Office Version: 2013 (no license)

 

My friends' specs:

Spoiler

CPU: Intel Core i7 3820QM

OS: Windows 7 (x64)

OS Version: [wherever win7 shows this]

OS Build: [wherever win7 shows that]

Office Version: 2016 (licensed)

 

My specs (I don't experience any crashes):

Spoiler

CPU: Intel Xeon X5650

OS: Windows 10 Education (x64)

OS Version: 1709

OS Build: 16299.192

Office Version: 2016 (licensed)

My dad just installed Malwarebytes and ran a scan and apart from some toolbars/adware, it came up with the following:

Files:
Generic.Malware/Suspicious, C:\WINDOWS\SYSTEM32\TASKS\OEM
Generic.Malware/Suspicious, C:\WINDOWS\OEM.EXE

Registry:
Generic.Malware/Suspicious, HKLM\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\SCHEDULE\TASKCACHE\TREE\OEM
Generic.Malware/Suspicious, HKLM\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\SCHEDULE\TASKCACHE\TASKS\{C12E9133-7F2C-4FD0-B43F-40C60529F1D7}
Generic.Malware/Suspicious, HKLM\SOFTWARE\MICROSOFT\WINDOWS NT\CURRENTVERSION\SCHEDULE\TASKCACHE\BOOT\{C12E9133-7F2C-4FD0-B43F-40C60529F1D7}

After moving all of these into quarantine, the office crashes were gone.

[Note: this so far only applies to the crashes my dad had. If this is my friends' issue as well remains to be seen.]

 

So this might just be a "regular" virus, but my speaking tinfoil hat whispers that (given the name "OEM.exe") it could also be Microsoft forcing you to update Windows (as in my friends' case) or buy an office License (as in my dads' case).
