Ok Samuel as Andrew says mate and these too

(ADW download from bleeping computer) delete any rubbish you find

@samuel pandit

If you still have avast installed and it cant update, do the following:

Download the definitions files manually from: avast! Software Updates | Download Latest Virus Database Updates

Click the top download button.

If you do not have avast installed any more, download Panda antivirus and malwarebytes. Run a full scan and report any findings.

May I respectively advise too Andrew that the OP uninstalls the other stuff first before it gets bogged down.

What I was going to suggest was uninstalling the Avast using the removal tool avast! Uninstall Utility | Download aswClear for avast! Removal and then reinstall it and maybe the updates will come down with it??
