The biggest obstacle to the use of F-Secure Anti Virus is likely to be well installation. Once you have inserted the CD into the drive, the program scans the first existing software installation and checks this for malicious programs. To this end, the computer several times down and up again driven. This whole procedure took at my Windows7 system 45 minutes to complete. The result was far reassuring that no malicious software has been found on my system.
When installation is complete, the program turns out to be pretty slim and resources. Compared with my previous program (Avira AntiVir) my system now runs a bit faster. As well, the program protects against viruses and malicious software.
