The Caz virus stays resident and infects COM and EXE files as they are executed.
If a file called CLEAN.* is executed, the virus will display the following text:
Virus anti-McAfee v1.0 (C) SEPTEMBER 1991 Made in SPAIN
After this the virus tries to overwrite data on the hard drive.
The Caz viruses are not common at all.
Some McAfee SCAN versions had false 'ZARAGOZA' alarms in all files protected with F-XLOCK utility. F-CHECK and INSTALL from F-Secure are examples of such files.
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.
