False alarm, or false positive, is an anti-virus term that denotes erroneous detection of a file or another object as malicious.
Though such cases are very rare, they may occur regardless of which anti-virus product you are using. Kaspersky Lab is continuously improving the internal system of product testing to decrease the percentage of false positives, but it is impossible to completely exclude them for objective reasons. The main of them is explosive growth of malicious programs, which are now measured by the million.
Kaspersky Lab currently delivers the world's fastest reaction to new threats by providing the users with hourly updates. It is expected that this practice will continue in further to ensure excellent user experience.
A questionable alternative to such solution is decreased reaction time. The risk of this approach is that the users may receive necessary updates by the time the unnoticed malware has infiltrated their computers and inflicted serious damage (for example, stole the bank account details, credit card numbers and so on). Thus, we are always in search for the best compromise between the reliability of protection and experience without false virus detections.
If you suspect a threat detection is false, please send a request to Kaspersky Virus Lab. Specify False alarm for a file or False alarm for a website as the subject. You can attach a suspicious object (provided that its size if within the limit) or a link to a suspicious website.
