Threat Metric
The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Kepsy is a worm that usually is installed as part of a component of Bublik and other multiple-component PC threats. As just a small tool in a large toolkit of software that's devoted to attacking your PC, Kepsy's main duty is to assist with Bublik's distribution by spamming instant messenger communications with links to Bublik enclosed within them. Kepsy also may interfere with other features of Skype to avoid detection. SpywareRemove.com malware researchers recommend that you avoid any contact with a Kepsy-infected PC, which usually will be infected by Bublik and, potentially, other types of malware with self-distribution features. However, professional anti-malware applications should be able to delete Kepsy and Bublik entirely if given the opportunity to do so.
Kepsy: the Helping Hand to a Security Hazard
Rather than being an independently-functioning malware program, Kepsy usually is installed as just one part of a larger infection, which, in current analyses, inevitably is the fellow worm Bublik. Current versions of Kepsy limit their attacks to two major functions, only one of which even is targeted at the PC that Kepsy infects. SpywareRemove.com malware experts outlined these attacks as follows:
- Kepsy will send Skype-based instant messaging spam to harvested account names. This spam is used to distribute Bublik, a related worm that includes major downloading and backdoor-related features that form the bulk of any Kepsy-Bublik combination infection. A typical spam message from Kepsy will disguise the installer link to Bublik as a harmless file, such as a picture.
- To cover up its tracks from the above operation, Kepsy also erases the PC user's Skype history. This prevents the PC user from being aware of Kepsy's exploitation of Skype to distribute Bublik.
What It Comes Down to When You Let Kepsy Do As It Wilt with Your Instant Messenger
While Kepsy may cause some minor system instability issues by using your PC's RAM and other resources to distribute spam messages, SpywareRemove.com malware researchers warn that Kepsy doesn't have any highly visible symptoms that would tip victims off to its presence. Likewise, its fellow worm, Bublik, also avoids displaying signs of its attacks – even while Bublik compromises your PC's security and as good as gives total control of your PC to a criminally-operated server.
Since Kepsy usually is related to Bublik infections, SpywareRemove.com malware researchers strongly urge you to use anti-malware software with extensive scanning features to detect Kepsy and related PC threats. Deleting Kepsy also requires that you delete, at the very least, Bublik. Until this is accomplished, you should prevent other PCs from accessing your computer's network-shared folders or sharing removable devices (USB drives, etc). In addition to the previously-mentioned Skype spam, either of these routes can be used as Bublik infection vectors.
