Found sistray.exe on your computer and don’t know if it should be there or not? Don’t fret–you’re not the only one. Fortunately, this program is usually harmless.
Sistray.exe helps with your graphics and is completely harmless–99% of the time.
SiS stands for Silicon Integrated Systems. The SiS Mirage 3 integrated graphics chip allows computers to smoothly run 3D gaming graphics. It enables the graphics card to switch clock settings automatically from 3D to 2D, which saves on CPU resources.
Sistray.exe makes it show up in the system tray on your computer. This is the bar at the bottom-right of your windows screen that shows various icons (such as the Battery icon on laptops, and the Speakers/Volume icon on almost every windows computer in the world).
A malicious file also poses as this file.
It’s not a very common occurrence–but it does happen. There is a Trojan virus called Prova that has a file called sistray.exe. The file information will of course not list it as a virus.
How can you know if this file is “the real deal” or not? Right-click on the icon or the file’s listing in your file manager. Click on “properties” or “about” to see who or what program owns the file. If a program other than Silicon Integrated Systems claims it, you may have a malicious file on your hands.
Anti-virus and anti-spyware programs do not take care of the whole problem.
If the sistray.exe file on your computer is from a rogue piece of software, then you definitely should run an anti-virus program to remove the Prova Trojan!
Unfortunately, anti-virus programs often do not clean up the mess that malicious software leaves behind. You may still have problems with your Windows registry.
The Windows registry is a database that coordinates all of your system’s process files with one another, and with your computer hardware. Without it, your computer would take way too long to perform even the simplest operation.
Unfortunately, programs like Trojan horses and viruses often leave this database damaged and “confused.” Even non-malicious programs can leave behind “junk” in the registry when they don’t properly uninstall (many don’t). The registry also becomes clutter through normal use, by no fault of the computer owner.
Regular application of a registry cleaning program will fix sistray.exe errors, as well as any other errors or damaged files.
