I’ll try to explain what I mean to say. Normally a full scan routine with avast is only performed once a fortnight. If you have a hunch of being infested do a full scan or even a boot time scan or go in safe mode to scan. With a partial scan I mean to scan where you think something can be flagged, so if you used a browser go to the location folder of the browser, say that is google and then scan all of that. When you think part of your user file may be infested scan that file.
If you think it is in systems scan that. Or just come here and ask what to scan or do the scans given in essexboy’s sticky in the virus and worms section of the forum (under guidance). If you have located something go and check on that file. Always double check with VirusTotal and URLs here:

 javascript:(function(){window.open('http://scanurl.net/?u='+encodeURIComponent(location.href)+'&k#results');})();
  • use this as a bookmarklet and drag to the browser bar.
    With MBAM and SAS you can do a full scan all the time all of the time when you feel the urge to scan. Check exe and dll here http://www.backgroundtask.eu/Systeemtaken/taakinfo/42925/new.exe/
    The proggie for the last changed files survey can be found here: http://www.file.net/freeware/last-changed-files.html
    The C: locations were excluded from these last changed files results on my laptol - user is given as pol here…
    That is all and I hope this may help.
    And by the way please do not describe such an experiment as other non-advanced users may follow your example not realizing the eventual risks involved,
