Hello everyone.

I am a huge open source fan, and was thrilled when I found out that Clamav had been ported to windows as Clamwin. When I tried it out however I was shocked at hor unbelievably slow it was. I have a 1TB drive and it takes over 24 hours to scan. I am very security consicous about my computer and I run Malwarebytes and windows defender. I was not surprised to find that Clamwin was still finding threats that Malwarebytes and Windows Defender were not catching, but I just couln’t live with how slow it was. After some extensive research I have found that if you use filters for dangerous file extensions, Clamwin will only scan those files and will considerably speed up clamwin. After I entered all of the dangerous file extensions under the settings>Filters tabs my scan time went from over 24-hours to 6.5 minutes for a 1TB drive. It sucks that you have to eneter each extension individually, but it’s worth it. See the list of filter file extensions below.

Most dangerous file extensions filter to speed up Clamwin *.exe *.doc *.docm *.docx *.hta *.html *.htm *.js *.jar *.vbs *.vb *.pdf *.sfx *.bat *.dll *.tmp *.py *.msi *.msp *.com *.zip *.gadget *.cmd *.vbe *.pse *.ps1 *.ps1xml *.ps2 *.ps2xml *.psc1 *.psc2 *.lnk *.inf *.scf *.xls *.swf *.ppt *.rtf
