Just ran the free ZoneAlarm/iolo technologies System Checkup. "ZoneAlarm® System Checkup™ performs a rapid analysis of the most critical parts of your system and then automatically generates a detailed report that provides information on overall security, optimization levels, clutter, and hidden errors that cause crashes, instability, and decreased performance." It appears my computer is in a sad state It found - amongst other things - Security Software Check "No actively running antivirus software was detected on your system. Without virus protection, your PC runs a very high risk of being inadvertently infected with dangerous viruses." Despite the fact that ESET AV 3.0.621.0 (with the current virus signature database) is running. Made a few other mistakes as well. Not entirely sure that I would buy the iolo System Mechanic 7 offered to help me resolve my problems.
