Malware stopping explorer, MBAM, HJT etc working

[mattjones17]

Hi,

Sorry for making a second thread - i made one before and then replied to it before seeing that the rules dont allow it so please delete that - i've combined all the info into this one so we can start afresh

I've today been infected by a virus. I know where I got it from - and I can provide a link if that would help people to get it.

I had and a.exe b.exe and msa.exe - these dont seem to be coming up but sometings clearly wrong. ESET doesnt find anythign wrong at all - so I installed AVAST. However, after I installed it, the exe was deleted. I downloaded hijackthis and malwarebytes - but the EXEs for this were also delted (I tried the randomised version - to no avail).

My internet has been hijacked so Google searches transfer to random stuff. There was no trace of this in the DNS settings.

I renamed malwarebytes.exe to explorer.exe as advised on another forum - now explorer has stopped working and I think the malware is stopping it from starting.

I would greatly appreciate any help - I need some work done by tomorrow and its currently impossible

Thanks

Matt
