The last update of 2012 Kaspersky Antivirus software deletes the file adjust.exe from your UA folder listing it as a virus. The file is clean, Kaspersky was notified of the false positive and are correcting the issue on their end. Once corrected they will issue an update which will remove the file adjust.exe from the active virus/malware list stopping the file from deletion upon install. The update will download automatically if your software is set to automatically update its virus definition database. This only effects Kaspersky Anti Virus users, no other Anti Virus vendor shows the file adjust.exe as a virus or malware.
A quick work around is to create an exclusion list stopping the file from being removed from your system. The basics are below:
How to create an exclusion rule
In order to create an exclusion rule:
Open application settings window.
Select Protection on the left.
Click the Trusted Zone button in the Exclusions block.
Go to the tab Exclusion rules and click Add.
Select an exclusion type in the Properties field: Object and/or Threat type.
Object
Click select object and choose a file, folder or a mask to exclude.
Select a Component in the corresponding field. The rule will apply to the selected component.
Threat type
Click enter threat type to select a file, folder or a mask to exclude.
Select a Component in the corresponding field. The rule will apply to the selected component.
Rules can apply to the following protection components:
Virus scan,
File Anti-Virus,
Mail Anti-Virus (Kaspersky Anti-Virus 6.0 for Windows Workstations 6.0.4.x only),
Proactive Defense (Kaspersky Anti-Virus 6.0 for Windows Workstations 6.0.4.x only),
Web Anti-Virus (Kaspersky Anti-Virus 6.0 for Windows Workstations 6.0.4.x only).
A scan if a disk or folder containing excluded objects scans the entire disk/folder except the excluded objects. Yet you can force scan excluded objects from the contextual menu (by right-clicking).
Also you can create an exclusion rule from within a report window:
Right-click the report object you want excluded.
Choose the option Add to Trusted Zone.
An Exclusion rule window will open. Make sure that you are satisfied with the new exclusion rule settings. Object name and threat type fields are assigned automatically on the basis of the report data. Click OK to create the rule.
