Cleaner is a simple memoryresident virus which infects COM and EXE files when they are executed.
Cleaner activates on the 8th of September on every year. At this date, the virus will display the following text on the screen:
O HDD-CLEANER Version 2.0O O Copyright (c) 1997 (1st JAN) O OMade in Hungary, SopronO DESTRUCTION IN PROGRESS...
After this the virus overwrites the beginning of the hard drive. Only the first 16 sectors are overwritten, so recovery is possible.
Cleaner will also cause different compatibility problems. It was found in the wild in June 1997, after the Hungarian Magazine CHIP accidentally distributed it on their cover CD-ROM.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
