A new process just suddenly appearing in your Windows Task Manager can be somewhat worrying, especially if you’re at least vaguely aware of the programs that typically run in the background. Is the unsecapp.exe process safe? It’s interestingly named, to say the least, but is it a malicious file or just a normal part of the operating system?

The purpose of the alg.exe file is to allow applications, such as IM client software, FTP and Torrent applications to establish a connection between two computers using passive TCP/UDP ports over a server. This enables the user to access files and applications off another system, even if that system is protected by a firewall. Without this particular file, the security protocols would block all communication ports, forcing the end user to manually open available ports, which would leave the system vulnerable to malicious files and hackers.

Dlg.exe or Digital Line Detect is not a system process, so it is not required by the operating system. In fact, it belongs to a program developed by BVRP, who incidentally, are also known for creating internet security software. In this particular situation, the dlg.exe process is a part of a Phone Tools Software Suite, which offers faxing, emailing and phone book facilities.

If the computer locks up and becomes unresponsive, it may not be possible to access the Start menu and shut down in the usual way. Sometimes even the mouse fails to respond in the most serious lock-ups. When this happens there is only one option and that is to hold down the power button.

A quick look on Task Manager on any Windows system will show dllhost.exe running within the background. If you found this process running in the background of your system, then it’s likely you’ll want to know what it is, what it’s doing there and whether or not it is safe. To start with, I can say, categorically that it is supposed to be there.

The DNS Unlocker is essentially pop-ups and coupons that display on your web browser without your consent. DNS Unlocker is an adware program, which is basically a way of describing a potentially unwanted program (PUP), because it’s usually installed on the user’s computer without knowledge or consent, modifying the web browser settings in order to display those annoying pop-ups, every time you surf the web.

When it comes to locking a folder, there are a number of methods that you can use; the vast majority of these methods require you to at least use some kind of third party application. However, if you would like to know how to lock a folder using purely manually methods, then you have come to the right place. It’s more important you know that the methods outlined below, though very good, can be undone by an experienced computer user.

Is your computer running much slower than usual? Do you get lots of pop-ups? Does your computer exhibit any other unusual problems? If so, then there is a good chance that it is infected with malware – despite having antivirus software installed and running on your computer.
