Found this site when searching for details relating to a BSoD with a specific driver. Their page describing it (http://www.solvusoft.com/en/files/bsod-blue-screen-error/sys/windows/microsoft/windows-7-home-premium/rt86win7-sys/) just has a bunch of boilerplate text with a link to their "registry repair" software. Typical site trying to capitalize off people trying to search for driver/executable names online.
The site claims to offer driver updates for specific devices. But all the links lead to the same program.
Lenovo Update Tool is identical with Canon BJ-30 Update Tool.
This looks like malware.
Comments show mostly no trust, but the site rating is excellent - strange.
Claims to have driver updates, installs their Driver Doctor progam which then scans and claims you need to update several drivers. However when you attempt o update one or more, it forces you to have to Purchase the Program. BS, misleading, installs an unwanted and useless program to get you to buy it. You can get all the drivers FREE elsewhere, it is a waste of time and you money, DON'T FALL for it.
solvusoft.com is the homepage of Solvusoft, a software company with products such as DriverDoc and SupersonicPC, as well as other, system maintenance related utilities for Windows platform. Pretty clear pages, no ads that I could see, nor any malware. Seems trustworthy.
The "FileViewer Pro" is nothing else than a simple viewer for known files and hex viewer for unknown files. If you search for any file ending via Google you automatically get to this homepage: http://www.solvusoft.com/language/file-extensions/ where you don't get any further information about your ending if it's not totally common.
Pretending to provide hardware drivers. Tricks you by using your search term as filename. Scam to get you to install thier software. Too risky to actually let it install. NEVER TRUST a download when they've tried to trick you into installing it/
