Infected Laptop - can you help please?

[musicalman56]

Hi,
I have a laptop whch has been infected by WinpcAntivirus.
After searching the internet, I tried manually removing various files (winav.exe etc) and Registry entries, and while they don't show up any more, the fact that I can't run or reinstall Malwarebytes (even after renaming the files) makes me think that this rubbish is still there.
Any help would be gratefully appreciated!

Thanks,

John.

Just noticed the 8 steps to do first - sorry - will do that and return when done - except perhaps the Malwarebytes step - it won't install or run

OK Big problems apparently - with the 8 steps

1. Viruscan - 0 infections detected
2. CCleaner installed and used as requested
3. Viruscan disabled OK
4. Malwarebytes (Already installed but won't now) tried new download and install (including renaming files) won't work
5. Dowloaded Superantispyware (twice) - won't install) error message appears - SUPERAntiSpyWare Free Edition has encountered a problem and needs to close. We are sorry - etc. 6. Java is up to date
7 Hijackthis - won't install
8. Obviously logs not available.

Hope you can still help!

Hello musicalman56

See if you can run combofix ->

Please download combofix here -> https://www.techspot.com/downloads/5587-combofix.html

Before Saving it to Desktop, please rename it to something like 123.exe to stop malware from disabling it.

Now, please make sure no other programs are running, close all other windows.

Please double click on the file you downloaded. Follow the onscreen prompts to start the scan.
Once the scanning process has started please DO NOT click on the Combofix window or attempt to use your computer as this can cause the scanning process to stall.
It may take a while to complete scanning and this is normal.

You will be disconnected from the internet and your desktop icons/toolbars will disappear during scanning, do not worry, this is normal and it will be restored after
scanning has completed.

Combofix will create a logfile and display it after your computer has rebooted. Usually located in c:\combofix.txt, please attach it to your next post
