Happy New Year ! I now have serious reservations concerning A-Squared Free in view of the following facts: I have used Emisoft A-Squared Free on and off for years with only minor glitches. Recently, Emisoft started posting reminders to purchase their paid A-Squared Anti-Malware at the start of each scan. Since November, at the start of a full scan, Emisoft's A Squared Free instantly reported a malware warning labelled "Trace.Registry.180searchAssistant!A2" At the end of the scan, A-Squared Free would neither quarantine nor delete this reported malware although I ran the full scan twice. When I went to Emisoft's support venue to find a solution, Emisoft instructed me to download and install their A-Squared Anti-Malware ($40.00 if purchased) and to run that program's full scan. After having performed a full scan, A-Squared Anti-Malware failed to report finding the "Trace.Registry.180searchAssistant!A2" malware or any other malware and, instead, gave my computer a clean bill of health. I then reinstalled A Square Free and immediately got the "Trace.Registry.180searchAssistant!A2" warning at the very beginning of the full scan. I then ran full scans of my computer using SUPERAntiSpyware and Malwarebytes Anti-Malware both of which found no malware. I also ran full scans with Microsoft's Security Essentials which also found no malware. I formatted all partitions of my first hard drive and reinstalled Windows 7 64 after having fully scanned my second drive which was reported clean. I find it most curious that neither my most reliable Avast Pro, nor Microsoft Security Essentials nor SuperAntiSpyware nor Malwarebytes or even A-Squared Anti-Malware ITSELF reported finding the "Trace.Registry.180searchAssistant!A2" malware while only A Squared Free found that item, refused to quarantine or delete it and, instead, sent me to Emisoft's paid version for remedy .... I have completely removed all entries for A Squared (Free and Paid) from my computers. Would anyone care to offer an appreciation of these facts? Thank You.
