I can solve your virus problem and the other issue might be resolved in the process.
First run a scan with this online scanner (Use internet explorer to start the scanner):http://safety.live.comAfter
that scan finishes and has cleaned anything found, run this online scanner (Use internet explorer to start the scanner):http://www.eset.com/onlinescan/After
that scan finishes and cleaned anything found download and install the free trial of ESET NOD32 antivirus. Yes, you just scanned with that utility, however the downloadable version has a startup scan that checks any files that start with the system. If any malicious ones are located they are quarantined awaiting your decision to restore them or remove them.http://www.eset.com/products/nod32.phpAfter
you install the scanner restart your computer!
Regardless if it asks you to or not, restart your computer, then update the security definitions of scanner, then perform and in-depth scan on all hard-drives. After
the scan finishes and has removed any malicious files, download and install the free version of Ad-Aware:http://www.lavasoft.com/products/ad_aware_free.php
Once again, after you install it restart your computer. After
the restart update the security definitions then perform a Full Scan
the scan is complete and has removed any intrusions download and install Spybot Search & Destroy. NOTE: Do NOT install TeaTimer(.exe)!
You will be asked if you want it during the installation of Spybot. This utility will cause a possibly fatal conflict with NOD32 and can cause complications with your system! So please DO NOT
you install Spybot, restart your computer. After
the restart update the security definitions of spybot and run a scan. After
the scan completes remove any entries found then download and install AVG Anti-Rootkit Free:http://www.softpedia.com/get/Antivirus/AVG-Anti-Rootkit.shtmlAfter
installation restart your computer. After the restart perform an in-depth scan of all your hard-drives. After the scan download and install CCleaner.http://www.ccleaner.com
After installing CCleaner you do not
have to restart your computer. Simply start the application and run the cleaner. This will clean out the temporary directories of web browsers and popular applications where viruses will sometimes nest themselves waiting to strike. Cleaning out these directories often helps keep your system clean. After the cleaning finishes click on the, "registry" tab. Now scan for any issues. If anything is found select to fix the issues. When prompted, make a backup of the files and save this file to a location you can remember!
If for any reason removing these registry entries causes abnormalities you will double-click the file that you just saved and it will restore everything that was just erased. This is your computer's life-line if for some reason a critical system registry entry was erased. On the bright side, removing these issues from the registry might
fix your shut-down issue.
I hope you get this virus removed. Let me know if I can assist you further.
