Windows Scripting Host (WSH) is a double-edged sword. On one hand it can be used to make some very useful scripts to automate common Windows functions (for example, the Spell Checker script from PC911).
On the other hand, it can be very easy for a malicious user to make a virus using WSH. Script Sentry allows safe scripts to run on your system while alerting you if a script might harm your system.
In addition, Script Sentry prevents against malicious scripts hidden in ShellScrap (hidden SHS and SHB extensions) files, Word/Excel macro viruses, malicious HTA files, and accidentally run REG files.
You can specify which scripts/files should be allowed to run and Script Sentry will invisibly allow those to run. Script Sentry is a "set it and forget it" application so it takes up exactly 0MB of memory unless its needed. NOTE: Script Sentry is not a replacement for a good anti-virus program, but a supplement to it.
An anti-virus program might stop a script virus once you update its virus definition files, but before you do that the virus has a window of opportunity. Script Sentry will simply help close that window.

hkSFV is the simply the easiest and most automatic application to create or check SFV and MD5 files hkSFV is the simply the easiest and most automatic application to create or check SFV and MD5 files.
What is an .SFV? -- An .SFV file is a tiny list of files and CRCs, which allow you to check to see if the files you have downloaded are exactly what you are expecting. The CRC algorithm used in .SFV files allows you to see if the file you have has been changed, even a single byte, since the .SFV file was created.
What is an .MD5? -- In a sense, .MD5 did not exist until now, as md5sum is a popular Unix format similar to .SFV and Unix does not use file extensions the way Windows based systems do. .MD5 uses the md5 algorithm to compute its checksums, rather than the crc32 method used by .SFV. The md5 algorithm is almost as fast as crc32, but it is much more accurate at detecting changes in files.
If you need to ensure that your data or data you download is error free, this program is for you.
If youve got an .SFV or .MD5 file, this is the program for you.
If youd like to create an .SFV or .MD5 file, this is the program for you.
Main features:
- Easy installation and automatic uninstallation. (leaves no trace in the registry, even goes one step further than most programs and restores previous file associations when you remove it)
- One-click creation and checking of .SFVs and .MD5s
- Flawless & smooth upgrading to new versions (simply install the new version)
- Automatic association with .SFV files, and an option to fix file association when other programs steal it
- Handles .SFV and .MD5 files from any other program invisibly (including files created on *nix)
- Database / cache of previously checked files
- Batch .SFV and .MD5 checking! - queue up and check many .SFVs and .MD5s in one pass, specify a directory and check all the .SFVs and .MD5s in that directory (including subdirectories, if you want)
- Automatically find renamed files while checking .SFV or .MD5 files
- Enqueue .SFVs or .MD5s during file verification
- Recursive directory support during creation and verification
- Supports creation of .bad and .missing files, or deleting failed files
- Drag and drop .SFV or .MD5 file or directory to create/check .SFV or .MD5

As many as 20 to 30 processes may be running invisibly, silently in the background on your PC. Some hog system resources drastically slowing down your computer; others are a threat to security and privacy; others may be harmless.
The Windows Task Manager displays most of these processes but you have no information to learn and understand what is what.
Get the latest definitions and exhaustive advice on all the processes running on your PC.
