Hello joannaex,
What you could do is do a full scan with SmartDreck and check everything this finds.
Download StartDreck
http://www.greyknight17.com/spy/StartDreck.zipUnzip to its own folder and start the program:
Press 'Config'
Press 'mark all'
Uncheck the following boxes only:
System/Running Process -> List Modules
System/Drivers -> NT Services
System/Drivers -> NT Kernel- and FS-drivers
Press 'OK'
Press 'Save' and select the location to save the log file (default is the same folder as the application)
Post the log in this thread.
Then also try this: Download Silent runners.Vbs
http://www.silentrunners.org/Silent%20Runners.vbs1. Make sure you have any script blocking software disabled
2. Run the program. It will take a few minutes to complete.
3. Once complete it will produce a log named “StartupPrograms” with Your user and date in the filename. Open that txt file and posts it contents in your next post.
We (that means essexboy and little old me) will give it a glance if anything there starts up or runs that seems fishy,
