1 firewall active. If Comodo set up correctly then suggest "disabling" Window one. Major conflict/slow down potential here.
You should be fine w/ Avast plus free on-demand Malwarebytes MBAM. exe.
I would expect conflict & slow down problems when Ad-Aware is combined w/ Avast! so recommend you un-install Ad-Aware program since your happy w/ Avast!
After that, if you have, I'd run CCleaner or other cleaner, & then reboot. This should make major improvement noticeable.
You can get CCleaner SLIM (check "Other builds") for FREE from:
I had tried a whole bunch of anti viruses and found that Avast Home is the best one for my needs. It use to take five hours to scan my computer, around 200GB - this included my external hardware.
I was talking to a few people about a month ago and was told to get Ad aware and Malwarebytes because anti virus programs don't completely get rid of everything.
Now Avast takes 12 hours to scan, when I also set up Ad aware and Malwarebytes. Do they clash? I'm I over reacting with virus', malware, trojans etc?
I have Vista if that helps at all, as well a Windows firewall and Comodo firewall.
Thanks in advanced,
