A friend of mine is facing the same problem I faced a few days back. MyBrowser appearing and a few programmes trying to be installed on his pc. I took the initiative to run MBAM, FRST and aswMBR and I have attached the reports.
It seems he has no antivirus installed, is that correct?
Essexboy will be online in about 3-4 hours
yes that is correct he has nothing on. I will install avast but I am facing problems installing anything with the viruses
Due to the amount of malware on this system I am unable to paste the fix so it is attached at the end 
CAUTION : This fix is only valid for this specific machine, using it on another may break your computer
Save the attached fixlist.txt, to the same location as FRST.exe

PC is in much worse state than I expected. All apps keep crushing, can’t even run exe files on it so I will have to format it. Thank you once again for your time and effort.
