Sys Defenders also produces annoying security notifications that all are expected to scare PC users into purchasing its commercial version. Do NOT follow SysDefender’s suggestions! Save your money and get rid of this rogue anti-spyware without any hesitation!

SysDefenders is distributed with a help of Trojans. PC users are usually convinced to install video codecs when they want to watch something online but instead of these programs they download hidden Trojan. Additionally, this parasite installs Sys Defenders in the targeted machine and also creates fake malware files that drops in the system. There is no permission asked! Later, these files are detected by SysDefenders as malicious ones and the program returns that only its “full” version will remove everything.
