Please could anyone help. All day today my PC has been freezing a few minutes after startup. Sometimes, I strike it lucky and it stays on for a lot longer, but 8 times out of 10 it just freezes and I have to turn the PC off by holding the power button in.
I tried running a McAfee Virus scan and it kept closing, saying McAfee VirusScan - On Demand Scan has encountered a problem and needs to close. We are sorry for the inconvenience. The error signature stated: szAppName : mcods.exe szAppVer : 13.3.127.0 szModName : mvsscan.dll
szModVer : 13.3.130.0 offset : 00019fc0
Tried to use system restore and not even that works (I keep clicking next and nothing happens, it's as if i haven't clicked anything!).

Then I downloaded Malwarebytes' Anti-Malware. It installed but not running after install. I tried with changing the extension .exe also.

Then I downloaded Microsoft® Windows® Malicious Software Removal Tool. It is not even installing. I tried with changing the extension .exe also.

When I scan again with Mcafee, it finds 1 infection and removes but if I run the scan again it picks up the same virus. It is some 'HOOK' named virus.

Now I lost my restore points also. I can't even create restore points.

I do office work in my laptop. Please help me.

Thanks.
