User Comments

Software installed by credit card issuer to protect the security of your credit card by issuing unique, one-time, credit card numbers. Thus, if someone is able to capture the number they are not able to use it to access your credit card. When you enter a seller's purchase page, the software presents a popup and when you enter your username and password it automatically populates the credit card information fields with a unique (virtual) account number. It works smoothly, but I haven't enough experience for a more definitive rating.
This is part of the Citi-Bank virtual credit card account number generator.

Best practices for resolving BhoUCS issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active BhoUCS process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the BhoUCS.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
