MBAM Error Updating (122,0,MultiByteToWideChar)


Recommended Posts

A couple of days ago I posted about trying to remove XP Security Tool 2010. Evidently I put it in the wrong forum. The reply instructed me to try a few applications and then write back if I was not successful. Well I tried to open (as an administrator) mbam, Avira AntiVir, DeFogger, DDS, and GMER Rootkit Scanner. When I tried to run each one, I got the message:" Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." After all that wasted time, now I can't even get Windows Explorer to work and had to write this on another computer.

HELP! There is a special level of hell for the yahoos who write these malicious programs!


Here is my initial posting and the reply that I received:

In an effort to remove XP Security Tool 2010, I downloaded Anti-Malware on a flash drive (via another computer) and loaded it on the infected laptop. When the program automatically tried to update, I got this error: MBAM_ERROR_UPDATING(122,0,MultiByteToWideChar) The data area passed to a system call is too small. What the heck does that mean? I found an old thread on this forum that asked the writer to run a security check. Here is what I got when I did this:

Results of screen317's Security Check version 0.99.6

Windows Vista Service Pack 2 (UAC is enabled)

Internet Explorer 8


Antivirus/Firewall Check:

Windows Firewall Disabled!

CA Anti-Virus Plus

CA Personal Firewall
