ThreatExpert is an advanced automated threat analysis system designed to analyze and report the behavior of computer viruses, worms, trojans, adware, spyware, and other security -related risks in a fully automated mode. In only a few minutes ThreatExpert can process a sample and generate a highly detailed threat report with the level of technical detail that matches or exceeds antivirus industry standards such as those normally found in online virus encyclopedias. ThreatExpert is an innovative system of providing a rapid, detailed description and analysis of the behavioral effects and changes that a threat makes to a computer's operating system upon infection. System administrators and researchers can use this information to minimize the impact of a threat infection on a computer or network. Threats can end up on a computer from numerous sources, via e-mail, using chat programs such as Messenger or IRC programs, or by browsing sites containing malware on the Internet. Whilst the presence of a threat file on a computer does not necessarily compromise the computer itself, there are several mechanisms by which it can be run without the user's knowledge. Once run, the threat infection can result in unexpected computer behavior.

Jotti's malware scan is a free online scan service, utilizing various anti-virus programs to diagnose single files. This service is by no means 100% safe. If this scanner says 'OK', it does not necessarily mean the file is clean. There could be a whole new virus on the loose. NEVER rely on one single product only, not even this service, even though it utilizes several products. Therefore, We cannot and will not be held responsible for any damage caused by results presented by this non-profit online service. Scanning can take a while, since several scanners are being used, plus the fact some scanners use very high levels of (time consuming) heuristics.
