windows 7 restarts itself after connecting to internet
My laptop Lenovo 412 was infected with AV security virus. To remove this virus, I have used anti malware bytes, MC 2010 total protection anti virus software and removed infections. After this, when I log on to internet, within 5 minutes I will get a message
saying windows has encountered a critical issue and system will restart itself.
I have run sfc /scannow as Administrator. No integrity issues found.
On e scan with one care full protection, it has shown several infections and cured them.
At the end there was a message that 4 infections could not be cured i.e Trojan Rowindal
Please let me know how to proceeed

I don't have the windows installation DVD as lenova has not sent it.
As you don't have the DVD, I recommand to you to perform a System Restore in Windows 7.
http://www.sevenforums.com/tutorials/700-system-restore.html
Please choose a restore point that dates before the appearance of your problems.
If you find no restore point that can be used to solve your issue, please see with Lenova so that they send you the DVD and proceed by a repair operation.
Keep in mind that all your files or folders created after the restore date you will use will be deleted.

Hi,
I would like to provide the following suggestions:
1. By default, only the System account has access to the System Volume Information folder. You may spcifically give the Administrator the full permissions on this
folder and its subfolders and files, and then try to run the antivirus software to remove the virus again.
2. From this issue, I would like to suggest that you
contact McAfee support to see if they have special update or tools to complete
remove these 4 viruses, and check if there are other viruses.
3. Actually, the officially recommended method is still to format and re-install the compromised computer from a known good build (i.e. operating system CD + all
security patches while disconnected from the network). For more information on hacking, please see these links:

Thanks for the updates. I have installed kaspersky TDSKiller.exe. It found one malicious file pxnumci.sys in system32\drivers (not sure about correct name) After quarantining this file, internet was connecting and was stable.
But when ever I restart my m\c again the file was becoming active and I had to run TDSKiller each time.
I have unstalled J2SE(Java ) and after that, the file stopped appeaing. Now I'm able to connect to internet without issues. I have tried 4-5 times.
I'm scanning my m\c for any other issues with one care live, McAfee total protection, windows malicious software removal tool. I will monitor situation for next 2-3 days and post the results
