ProcessGuard

This utility provides competent PC protection, albeit in a different way than antivirus or anti-adware tools do. Rather than scanning your PC to ferret out specific offenders, ProcessGuard blocks all activities typical of malware and Trojan horses at a deep level. The program's interface is handy and requires minimal user configuration. However, you will need to run the utility in learning mode for several hours so ProcessGuard can examine your computer and determine which processes are safe. The application can prevent nefarious programs from reading, modifying, or stopping any application in the memory; disable access to physical memory; and stop unauthorized logging of drivers and services. It also provides additional protection by asking your permission every time a new application attempts to install. Although ProcessGuard demonstrated solid performance in our tests, we can't vouch for some of its more advanced features, which are disabled in this version. Still, the program makes a nice addition to your arsenal of PC-protection programs.
