Not a thing, trillions of errors out there. I would not trust it, process of elimination now.
Lets start with checks for malware/infections.
Please copy & paste instructions into a text file, print/write down steps & info. You will need them, as they are hard to remember, for when you are offline.
Note: Is your important stuff backed up, including your emails & address book. Anything can happen, during the clean up.
The badies are always ahead of the goodies, be aware, this can be a very long process, involving many different tools to clean up an infected comp.
As we dismantle the infection bit by bit, that may allow the repeat use of programs, which may in turn pick up more.
Removal of infected parts of the system, may cause other parts to stop working, such as your Internet connection or Services. These we then, have to repair later.
If any program won't run ( due to the infection ) let me know.
Copy & Paste the contents of the log/logs after running each program.
