Am not sure about this ''PC Cleaner'', how ever I have looked into a few of them and have found that they are trying to ''sell'' you their program. No matter who it is when ''they'' scan your pc, they will find quite a few problems, perhaps will even eleminate a few, however to remove the most of them, you must download a ''paid download program''Months ago I went thru the same thing, finally found a few good ''virus scans'' for free, and have had no problems of any kind.One of them is ''AVG virus scan'', another one is ''Avast'' hich is also good one. Again, have had no problems. Also one should download a couple ''Spyware cleaner'', which you also will neew. Good Luck. Walt
