The cybersecurity landscape is a dangerous one, as sophisticated hackers continue to wreak havoc on computer owners worldwide. A recent study by PandaLabs indicated that approximately 32 percent of all computers studied had malware, with at least 27 million new strains created in 2012. Trojans accounted for 75 percent of all malware attacks produced last year.

Viruses accounted for 8 percent of all of these incidents, according to the company, followed by worms with more than 6.4 percent.

This is not the only frightening trend discovered by PandaLabs. The popularity of social networking websites is putting consumers in danger of having their passwords exposed. For example, a security breach of LinkedIn led to the theft of 6.5 million passwords.

Consumers should do all they can to avoid being a victim of a major security breach. Industry professionals encourage people to use a password manager like Sticky Password to avoid using the same phrasing for each online account. If a cybercriminal can obtain a common password from someone, the malicious individual may have access to a person’s email, banking information or other sensitive information.

Mobile devices are another dangerous platform that can impact users and their data and passwords. PandaLabs said that the Android operating system is the most popular for cybercriminals looking for ways to steal information and money.

Smartphones powered by Android or Apple are likely to remain popular targets as more people adopt smartphones. Owners of the iPhone can also download password managers to their devices to ensure their information remains protected while browsing from their mobile gadgets.

With so many interactions taking place through the internet and via multiple devices, hackers will continue to target users involved with these popular channels. Consumers should strongly consider doing all they can to safeguard their most important information.

Disable Port Scanning on port 25 with McAfee

Last few day, I was working on client server and found out their ASP.Net script do not able to send out any email from IIS SMTP.

After further check, it is found out port 25 is blocked from McAfee AntiVirus.

1. Locate the McAfee icon in your taskbar. Double-click the icon to launch the application. You can also run the program by clicking “Start > All Programs > McAfee > McAfee VirusScan.”
2 Click “Virus Scan Enterprise > Virus Scan Console.” Double-click “Virus Protection.” Click the “Access Protection” tab.
3 Check “Prevent mass mailing worms from sending mail.” This will disable port 25. Click “Apply” to save your settings, then click “OK.”

Calculate Folder size with ASP.Net

It is very important for a server space to be available time by time instead of always getting disk critical error from a server.

However, it is not possible for a server administrator to always log into the server to check the available space or used space for a folder.

Instead of using the server script to send an email to the administrator, user could use the ASP.Net script to show the used space.

VB Script:

Imports System
Imports System.Linq
Imports System.IO

Module Module1

Sub Main()
   Dim dInfo As New DirectoryInfo("C:/Articles")
   ' set bool parameter to false if you
   ' do not want to include subdirectories.
   Dim sizeOfDir As Long = DirectorySize(dInfo, True)

   Console.WriteLine("Directory size in MB : " & _
    "{0:N2} MB", (CDbl(sizeOfDir)) / (1024 * 1024))

   Console.ReadLine()
End Sub

Private Function DirectorySize(ByVal dInfo As DirectoryInfo, _
   ByVal includeSubDir As Boolean) As Long
   ' Enumerate all the files
   Dim totalSize As Long = dInfo.EnumerateFiles() _
     .Sum(Function(file) file.Length)

   ' If Subdirectories are to be included
   If includeSubDir Then
     ' Enumerate all sub-directories
     totalSize += dInfo.EnumerateDirectories() _
      .Sum(Function(dir) DirectorySize(dir, True))
   End If
   Return totalSize
End Function

End Module
