thanks you two for taking such an interest.
OK, so I've printed off all the instructions and am ready to follow them to the letter, but have stalled at the first pot hole. I can't get into Spybot no matter which way I try, I just get the message "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." If I can't access it, how do I temporarily disable it, or has the spyware kindly disabled it for me, in which case do I need to worry about this step?
Similarly Windows Defender, which I downloaded last week, tells me "Application failed to initialise. (Ox800106ba) A problem caused this program's services to stop."
Also, none of the lists in the link say anything about CCleaner - do I need to disable that too?
Here is some more info about what is happening:
Now when I start up the computer I get all sorts of error messages:
dsca.exe Application error. The application failed to initialise properly.
Windows defender Application failed to initialise. (Ox800106ba) A problem caused this program's services to stop.
pcdrsysinfostorage.p5x Application error. The application failed to initialise properly. (0xc0000142).
Spybot S&D resident has taken to popping up constantly in little balloons at the bottom right of the screen, telling me 'New processes are being scanned.' I got rid of this by right clicking on the little icon there and selecting Exit.
Now I can get on the internet, but whenever I try to actually enter a site (e.g. Compare the market.com when you have to put in your details in order to get a quote, or googlemail log in) Microsoft encounters a problem and has to close. Sometimes it takes a while to close the website down and the computer stalls. When I do the control-alt-delete thing I am told "Task manager has been disabled by your administrator."
Following one of the links on your firewall tutorial I was on the Microsoft update website. It told me that I needed Windows defender Definition update to be installed - it said it was already downloaded. The installation failed, though, quoting KB915597 Definition 22.214.171.124 Not installed.
This is all now driving me nuts! Please advise! Do I go ahead with the Malwarebytes thing? I have saved it to my desktop as instructed.
I hope I've replied in the right place, sorry if I haven't
