I keep getting mixed opinions on the net. I'm going to leave it alone
Dva.386 is a standard windows system file, (Default location is windowssystemdva.386) a virtual device driver for windows video software. dva.386 is a Windows System File and should be in a system directory. If it is then this application is safe. -- Disclaimer: Every attempt has been made to ensure the information about dva.386 is accurate but alot of malware applications try to pose as valid applications.

relateed Video 4 Windows lib. as mentioned by others above - but name alias is sometimes abused by intruder. Be aware if running TSR mode, in that case you could compare it by size and CRC has to identify if it is correct version or not. Alternate check: stop the related SERVICE via Service CP, if still found runing after that you´r machine is most proably infected. ! Infection is usually detected by most common AV progs, usually there´s no need for manual check. REMEMBER to make alway a BACKUP first!

Best practices for resolving dva issues

A clean and tidy computer is the key requirement for avoiding problems with dva. 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.

To help you analyze the dva.386 process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
