Many many thanks for your help with this problem, The P.C seems to be running a lot better now thanks to all your instructions and tools you told me to use.
I will slowly digest what you have written about the extra bits and pieces for keeping my system clean etc. I will certainly join the complaints forum although what i'd like to do to the people responsible may not be suitable for the general members to read!!!!!
John, should i now uninstal combofix, atf cleaner, malewarebytes or should i leave them on my P.C?
Point taken about internet explorer. I do have firefox installed on the P.C and shall endevour to use it from now on.
Thanks again for all your help. Without people like yourself, myself and many others i suspect would be in grave trouble with P.C problems.
Thanks again
Regards
Steve
