is a comprehensive optimization suite by iolo that purports to improve performance, make repairs and enhance the speed of a computer. It includes a registry cleaner, a registry revitalizer (to fix "so called problems
"), system optimizer and several other features.System Mechanic Pro
incorporates the same optimization suite but also purports to plug security holes and protect privacy, and includes System Shield AntiVirus & AntiSpyware
. There are several labs which test the effectiveness of major anti-virus programs to include AV-Comparatives.org, Virus Bulletin Comparative Tests, AV-Test.org, NSS Labs Consumer Anti-Malware Products Group Test Report, etc. I cannot find any which have tested
System Shield AntiVirus & AntiSpyware. I would be skeptical of any vendor not participating in comparative testing
. As such, I would recommend replacing System Shield with a more reputable anti-virus solution.
The optimization and performance improvement claims made by such software vendors are borderline scams
. There is no statistical evidence
to back such claims. Advertisements to do so are a marketing ploy intended to goad users into using an unnecessary and potential dangerous product. I would not trust any results
the program detects as problematic or needing repair nor recommend using the options to fix them. I also would not trust any detection alerts for viruses or other malware.
Further, these types of junk optimization programs are often considered Potentially Unwanted Programs (PUPs)
so they may be detected or even removed by some security scanners which specifically look for PUPs and adware.
