MajorGeek says: F-Secure Online Scanner attempts to fill in yet another niche in the removal of anti-malware. In this case it only scans ?important locations?. The best I can tell it scanned my memory as well as the Windows and Users folders and not much else. The scan took just one minute on a very fast computer and when nothing was found it took me to the F-Secure page to sell me on F-Secure products. At this point I downloaded a virus and placed it in my Users and Windows folder and the program did not find it. Since this easily downloadable test virus is well known, F-Secure should have easily found it. Screenshot #3 below shows the dummyvir placed in my Users folder.I can't be sure at this point if it's just useful for memory scanning or if it's nothing more than a program designed to sell their products. F-Secure has a stellar reputation so I will assume it has a niche I just didn't find.
