On boot up I get the error message below and sometimes when a new program is started. Can you tell m

The error message reads;

The insttruction at "0x66006041" referenced memory at "0x66006041". The memory could not be "written".

Click OK to terminate the program.

Click Cancel to debug the program.

I have tried every thing I know of to get rid of this thing. Can you help?

One person told me it is a residual from a virus that is no longer there.

I use the Avast anti virus program as well as Ewido, Ad-Aware Ccleaner and Spy Bot.

Dr. Watson sees the problem but is no help in fixing it.

First use the antivirus and antispyware software you have to run a full system scan. Do it in the windows safe mode. (AVG and avast antivirus softwares are free while a 6 month free trial for Norton is available at pack.google.com. Lavasoft's free Ad-Aware is the best antispyware to my knowledge. Also Windows Defender from Microsoft is good enough for real-time protection). This should identify the problem and most probably would solve it as well. However, if the antivirus software is unable to delete the malware, go to Norton's website and search for the name of the malware detected. Their must be some instructions posted to tackle the problem. You might have to delete the system restore points and as well delete the particular registry entries manually if the virus still regenerates on subsequent boot up of the machine. Good Luck.
