Ah I see, thanks. If there's an option to keep it I might just do that, bit wary about the whole process to be honest, as I've never done it and don't want to cock it up, but it does look like it needs doing.
In the absence of a bootable machine though, and yours over the weekend, and due to exhausting my attempts to get the machine to boot (think the MBR had somehow been screwed up, maybe by the "trojan" or whatever, but nothing I found and tried worked - even fixes marked "this works for everyone"!
) I've decided to restore the system image for now, just so I can have a working machine which I can get a full program list off of and also do a full file check and backup in Windows (rather than more painfully with dos in the RE!).
So I'm now back to my pre-Repair install state, with non-working WU, and just checked MBAM and it's
Still found the same trojan in rpcss.dll+ that it found last week, after all the updates etc!
not sure how if the machines been rolled back, and MBAM is the only scanner that picked it up! Even Virustotal says it's clear (0/57, including with Malwarebytes!), and looking online it appears that this file isn't even needed for Windows 7 (the rpcss.dll that is, I can't find any reference online to a .dll+!!
), so I'm wondering if it was maybe a false positive? It's quarantined and gone though (apparently, I had to delete it manually even though MBAM said it had quarantined it...) so hopefully no issues there...
Anyway I'm going to run all the scans I can to be safe, update as much software as I can (including Windows if it will), then I've got my move to sort out and then a huge backload of work to tackle as well just to try and keep afloat.
It's probably going to be a couple of weeks at least before I get round to getting back here to doing a clean install and the stuff mentioned that's needed before that, so I'm going to mark this as Solved (as it essentially was as far as the updates and missing service package files were concerned before I restored the system image) and then if I have any issues or questions with the install I'll post a new topic at that point.
And before I forget or sign off temporarily (though I'll still be around), many big Thanks again Shane & Boggin and all on here who have helped, greatly appreciate it all
