The key words here are SAFE MODE!!!
Turn System Restore off. Click Start, right-click My Computer, and then click Properties.
In the System Properties dialog box, click the System Restore tab.
Click to select the Turn off System Restore check box. Or, click to select the Turn off System Restore on all drives check box. Click OK.
Click Yes to confirm that you want to turn off System Restore.
Download, (if you can't get on-line, have a friend download and copy to disc/flash for transfer) install, update and then in SAFE MODE* run full scans with these programs...

**Note: Malwarebytes should be run in 'Normal Mode' unless that isn't possible!

Then re-start.
Turn System Restore on. Click Start, right-click My Computer, and then click Properties.
In the System Properties dialog box, click the System Restore tab.
Click to clear the Turn off System Restore check box. Or, click the Turn on System Restore on all drives check box.
Click OK.
If you can't run a scan, go into the scanner's folder and re-name the .exe file to something like 'MyFile.exe' and try in safe mode again. Some malware prevent the execution of anti spy/mal/virus scans by blocking them by name.
You should consider getting a good Anti-Virus program.
Try one of these free ones...

*Note: On start up (before Windows loads) keep tapping either F5 or F8 (be aware that some manufacturers use F8 for system recovery!) then use arrow keys to highlight 'Safe Mode with networking' and hit Enter/Return, click on a user account, enter the Administrator password (if you don't know it, there probably isn't one so leave it blank) and hit Enter/Return.
