    Hopefully I'm posting in the correct forum.

    I tried ESET on line scan yesterday and it took so long I canceled it.
    Today I tried it again on a different computer, even slower.

    I can watch the file names being scanned and the file extension is related to how long the scan takes. This is understandable.

    .exe files, up to 10 seconds, or more.
    .chm files, up to 30 seconds.
    .jar files, minutes each - really.
    For example RT.JAR scanned in about 2 minutes on computer #1. On computer #2 RT.JAR scanned in 4 to 5 Minutes. That is crazy. :-(

    Am I doing something wrong or should I be looking at different AV software?

    Does the installed version run any faster?

    I dont know if the NOD32 program scans faster then the online scanner but the online scan might be slow(er) cause you have a real-time program running which also scans the files which the online-scanner is scanning. Ofcours you can install the trial version and see for yourself.

    You might want to try the 'Release candidate' online scanner @ http://beta.eset.com/eos - This one scans pretty fast on pc's I used it for. Works like a charm.

    In my experience, the online scanner is much slower than the normal one...

    I had a neighbor use the online scanner once... and it appeared to take twice as long, but did the trick...

    At least 2x slow, maybe 5x slow. My C drive holds only 18GB and the on-line scan took 2 hours and 45 minutes to complete.

    The file, RT.JAR, scanned for 4 to 5 minutes all by itself. :thumbd: :thumbd: :thumbd:

    At that point it suggested that I would want to jump at the chance to purchase it. I don't think so.

    Thanks for the response.

    I am not affiliated with ESET, but I do like their AV product... It sounds like something else was running heavily against the hard drive at the same time the online scan was...

    Is another antivirus program resident on the system? If so, then it is likely that all scan operations are performed twice as each program scans the files.
