I've done several daft things -
initially I has the "PC speed test" virus on my PC.
I found 2 possible solutions: combofix and regcure.
regcure seemed to require 3 programs in sequence and seemed a more labourious and plausible so I ran it (stupid mistake 1).
I was halfway through running the 2nd program (having said yes to change my registry) when I discovered regcure is also probably malware !
I stopped it and tried to remove Regcure using a forced unsintall from iobit.
I also started to run combofix
Combofix ran for a long time (40 mins) through all the stages and started to report deleting files.
But what seemed bad was all my icons vanished - I could see the wallpaper clear as day.
So I stopped combofix.
I rebooted the PC and it reboots OK but not sure what to now.
I'd like to run combofix and let it do its stuff ??
At least the PC is old, a bit flakey and most of its important stuff is backed up - I'd have already chucked it but it has some usefulish software that I won't be able to reinstall easily.
