Posted on 2007-08-04

My Toshiba Satellite A75, Win XP has a virus that I cannot delete using Norton Antivirus. I get the following message:

"The compressed file maximizer_startup.exe within C:\Program Files\Notebook Maximizer\update.exe is infected with the Downloader virus."

How bad is this and how can I get rid of it?

    Delete or rename the file update.exe manually. Maybe you'll have to do that in safe mode.

    Start the machine in safe mode and try running a virus scan.

    If that fails go to start > run > msconfig  thyen disable every thing in the startup tab and then in the services tab select "hide all microsoft services " then diasble every thing that is left. and try rerunning the virus scan again.

    If that still fails follow petelongs instructions about malware here

    and try that .

    Could very well be a "false positive" from Norton AV. Application seems to be a legitimate Toshiba utility.

    Try an on-line virus scan such as Housecall to help verify/negate Norton results:

    If you want to be almost positively sure that the file in question is being detected as a false positive you can use a comprehensive scan to test it against a miriad of anti-virus solutions.

    Scan your file over at VirusTotal to see what the other popular AV products think of it:

    The service is free and actively supported by many major AV companies.

    This is easily could be a false positive detection as the file "update.exe" has been used a lot by malware writers.

    This could also be a real file infector, Kaspersky(trial version) does a good job of cleaning it. Or we could also check if you really have file infectors present there (by running a scanner that detects file infectors)as other files will be infected as well.

    Or as already suggested by Maeros, submit that file for an online check -->
