Symptoms

Symptoms are usually visible means that can help users determine whether the threat being discussed on < href='http://www.trendmicro.com/vinfo'>Trend Micro’s Security Information page has affected their system. File name and file size are not enough to indicate whether system is indeed affected. However, this information, plus other information like registry entries and other system changes, can help users assess their system, short of using an antivirus product to check for detections. For grayware descriptions, the author/creator of the software is also indicated.

Other information, like the Web site where the malware and grayware are usually located, is sometimes indicated in a specific threat description. This may help alert users that these sites are malicious sites, and should be avoided.
