I am not very good with computers being in my 60,s but I have a virus/trojan called Qsearch.com lurking on my computer? none of my virus remover progammes are able to remove it because it acts like a browser, as soon as I go onto the internet Qsearch.com takes over from google. I have managed to stop it by asking avast to block it from loading then clicking on google to make google my search engine, but as soon as I close my browser and start up again it reappears. I was told on youtube that if I scan with Superantispyware, then Malwarebytes and the with Kapinsky this will remove it, but when I tried loading Kapinsky anti spyware, Avast closed my computer down. This Qsearch.com is well known on the internet as a browser hijacker why can not Avast remove it?HELP please!I am using mozilla firefox.

Thank you for your quick reply I did as you suggested, but the notepad windows did not appear, and they are not with OTL in my downloads, so I am going to give it another try I think the CREATRESTOREPOINT was missing of my copy and paste :
Will this process be affected by me having the URL for Qsearch blocked?
as instructed above…

Something bad is happening I can not access my documents anymore ??? and I have had trouble even getting back on this forum?
Try this:
Wow I am back I thought all my files had been wiped clean nothing would come up, even accessories
was showing empty ??? so I could not get to system restore? I rebooted and system restore came back so I restored back to early December 2011 and everything seems to be working except all my passwords for forums need resetting, but so far Qsearch seems to have vanished, if I have to use the procedure you recommended I will get my son to do it because he his more competent than me 
Thank you for your time and advice.
this is essexboy post i just quoted it…he is the guy to be thanked first! ;D
