Here are a few suggestions on regular maintenance in addition to the ones given to you already to keep you and your machine safer in the future:
1. Keep your definitions up to date for both Avast and MBAM.
2. Keep all your shields on with Avast.
3. Update MBAM
prior to scanning, then do Quick scans.
4. Keep your MS/Windows Updates current.
5. Add security related Add-on’s to your browsers for safer browsing. See my Signature as an example.
6. Use common sense when browsing and do not go to risky sites.
7. When downloading software, read what you are clicking and do not download adware toolbars which are commonly opted in; look before you click or do a Custom install to avoid putting unwanted toolbars on your machine that lead to spyware tracking or adware.
8. Check to see that your software is up to date with the
free Secunia Software Inspector http://secunia.com/vulnerability_scanning/personal/ since software is changing all the time. This site gives you the vendor's direct download link making it easy to upgrade your software. Many of us here scan our machines weekly.
9. Use CCleaner (CC) after closing your browser regularly. You can also use TFC as needed (depends on your Internet usage - perhaps weekly, or if suspected of malware) in addition to CC.
Let us know if you have any other additional questions.
