Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.
ESET Online Scan FAQs
Why does ESET Online Scanner run slowly on my computer?
If you have other anti-virus, anti-spyware or anti-malware programs running on your computer, they may intercept the scan being performed by the ESET Online Scanner and slow it down. You may wish to disable the real-time protection components of your other security software before running the ESET Online Scanner. Remember to turn them back on after you are finished!
Other programs like Panda ActiveScan uses non-encrypted virus definitions so its best to disable your resident anti-virus program before scanning in order to avoid "false detections
" of its files.
