Part 1. I have used F-Prot for Windows for well over a year and I am impressed by this seemingly 'little-used AV'. Compared to other programs, I have seen very few posts about it here at Wilders. So here are some personal observations about it which might persuade some people, at license renewal time, to give this AV a spin. Thanks to Tinribs and LowWatermark for their comments on F-Prot. Advantages; * Amongst the top group of AV programs for virus detection as judged in a variety of test sites, including virus bulletin, av-test org etc. It frequently scores 100% detection of ITW viruses and also has very high 'zoo' detection abilities. Large bank of malware, containing at the present time over 86,000 definitions. * Has a very small memory imprint. Only one running process, F-StopW.exe, the running guard, which uses 304Kb of VM and 1.77Mb of memory. It therefore has virtually no effect on system resources.. To support this, I have seen it working without any visible detrimental effects on a lowly Pentium 1, 75Mhz with 16Mb memory. I am sure it can go even lower than this! Overall, this AV has no effect on the speed of your computer and systems remain stable. * Updates are weekly, although virus update files are quickly updated when a new virus is found. For example this week, I have had 4 downloads after notification e-mails from the Frisk Alert Service. In addition, they are amongst the quickest of the AV companies in sending out the definition files to any new malware. * Support is very good and quick and I have always received a response back within 24 hours, generally within hours. Individuals, not just companies, are well supported, as when I had problems with the automatic updater for one of the versions, they sent me a 'new' updater which solved my problems. * Runs happily on all versions of Windows, including 95. * No multiple licenses are required, so with the one copy of F-Prot you can load it on all of your home machines. * Relatively cheap at $29, but the real bargain comes with multiple licenses for companies/ educational colleges etc. where it can work out as low as $2 for protection. * Very easy to set up for newbies as the main GUI is very straightforward. The scheduler is well set out and it is easy to schedule scans and downloads. There are 'normal' and 'advanced' settings to select. *Scan speed is fast. For example with all-files selected, I can scan my entire disc in 8 minutes. NOD beta5 takes 4 minutes and KAV takes 17 mins. And I have rarely come across any false positives in over 19 months, except one where I was trialing BitDefender. * Includes F-Prot for DOS and Disinfection is said to be very good. Compared to other AV programs, it is a relatively small download (7Mb) which only takes up 9.56 Mb of hard disc space when installed. * 3-4 'minor' new versions/updates/year which have recently concentrated upon the scanner speed. A completely new version 4 is due early next year with a number of new features. *The uninstaller is very good.
