hi, thanks for your reply, i am running dr web as we speak, it has initialy found what it says is a backdoor.tdss.565 in the system32\svchost.exe file although i am still gettin avast sayin it keeps finding the same issues in the temp file, dr web says its eradicated this issue but still seems its coming back, i did do a quick scan with dr web before and it found the same as i have just decribed as above in the system32 folder, so it seems when it fixes the problem it just comes back somehow.
i have joined the forum that was mentioned and awaiting feedback from there.
also rootrepeal will not work on my laptop, each time i open it i get errors saying differnet thigns have failed to load, and as i try to do a scan it says it cant find the driver to work, i even got a blue screen from tryin to use it.
dr web is doing a ful scan at the mo and seemed like its gonna take a good hour or more to finish, i will let you know how i get on, this software has at least fond something in my system32 folder anyway, just makes me wonder why avast cant?
