With regard to the above, please let me know  if this is a problem with f-secure or it is a malware problem.

    With the information given, we have no way of knowing. Sometimes, this can be a symptom of having more than one anti-virus program installed, as this can cause conflicts.


    If you suspect malware, then a scan with www.Malwarebytes.org may answer that question.

    Download and run AVG Remover from here, then reboot your machine:


    If that doesn't fix things, then download and run the F-Secure Uninstall Tool from the link below, reboot, then reinstall F-Secure:

    Scanned with downloaded free trial version of Malwarebytes and removed most of the malware....you were right...and the disk usage seems to be normal...thanx a ton....should i uninstall malwarebytes program.....

    Depends which version of Malwarebytes.  If it's the free one, which I don't think runs in real time, then it will be OK to stay, and you can just run a scan with it periodically.  Malwarebytes 2.02 is fine to run in real time, as it is compatible with F-Secure, but Malwarebytes 3.0 may give you problems, as it did me.


    I would still recommend that you run the AVG Remover tool, as the auto-uninstall F-Secure carried out may not have removed all of AVG's components, and this may lead to problems further on.
