Windows Tools, Help & Guides

A file’s hash value is a signature for that file that uniquely identifies it. If a file’s contents change, its hash value will also change. You can use the hash value of a file to know whether it has been modified or altered. You can also cross-check the hashes of a suspicious file online to see if it’s a malicious file. Windows 7 does not have any native way to show or calculate a file’s hashes. But you can use the freeware HashTab tool to add a File Hashes tab in the file properties dialog.

Windows Forums member and owner of Real Security, geohac, has updated his comprehensive guide to help users remove malware from their PC. In the guide, geohac covers steps you should take to prepare for removal such as disabling proxy servers (to give you a better chance at getting online and getting to the sites you need for virus removal software.) The guide then goes on to show you how to boot into safe mode to fight a virus (something we recommend ourselves) and then shows you which tools you should use to remove a virus (downloading these tools on a non-infected PC is the safest bet and making sure, if you have to use a USB drive to transfer the files, that you don’t put the same, now potentially infected, thumb drive back in the clean PC.)

If you use online banking, you may have noticed when you get your password wrong that the error in response is pretty generic i.e. “Wrong user name or password.” These error messages are pretty unhelpful; however, this is by design. If someone tries to compromise your account, do you really want them knowing they got the user name right and now just need to tackle the password? Probably not. The harder we make it to get in to our accounts, the less chance we have of opportunists getting to places we don’t want them to be. With that said, this guide will show you how to disable user name display on the Windows logon screen, for additional security.
