Windows defender & Avast didn't start, extremely slow computer at startup.

So, my computer is running especially slow at the start and sporadicaly. It never happenned before and I have a quite powerful computer. Also, today when I first started my computer avast and windows defender didn’t seem to start and windows asked me to activate them, which I did. But that shouldn’t happen either.

Recently, I downloaded two games through the steam platform(http://store.steampowered.com/) and avast wanted to open both game in sandbox because it tough it was unsafe but not identified as a virus. I looked at the name of the file, then openned them normally because I knew the game was safe, I have 120 games on steam, and it only started showing me that ‘‘open in sandbox’’ recently when I open the two of them. It also wanted to open OTL in sandbox, and again, choose to open it normally.

The two games are: Dota 2 and Orcs must die.

The slowing of my computer is pretty HARD, its not something normal, and also the fact that windows defender and avast didn’t start at first lead me to believe that I have been infected. Here are the logs to help you, help me.

Thanks!

PS: ASWMBR.exe crashed during the scan. It never worked.

You might want to start by disabling Windows Defender. It has been known to be a memory hog and doesn’t really provide you with additional protection if you have avast!

Go to the Control Panel or to the Start Button type “Services” and strike the Enter key. The Services GUI should pop-up. The Services should be listed alphabetically. Go down until you find the line that says Windows Defender look to right and it you should see a columns entitled “Start-up Type”. Double click on the Windows Defender line where its gives you the Start-up Type. Then click on the Disable option. Exit and reboot. See what happens.

Well, thats fine and all but It have been running since I have this computer(1 year at least) and I never had conflict problem. The thing is, when avast crash, like it happenned once, I have still another layer of protection, at least thats my understanding.

That being said, Im still wondering my computer sudently became very slow(laggy) at startup and that only recently. It doesnt seem infected when reading the logs and scanning… but still… both defender and avast crashed at startup and I find it very wierd.

Also, a website I have been visiting since a while(4 months at least) now have been poping avast blocking malicious URL. www.projectzomboid.com > forums. Did that yesterday, will check if it keep poping it today.

I can’t tell if you followed my suggestion or not. It sounds like you didn’t.

It also sounds like you don’t have a lot of confidence in avast! if you are worried about it “crashing” in the future. I think avast! is a great product. However, my suggestion is to not use any software that you live in fear of it crashing. You will sleep better at night. :slight_smile:

Or discover which other one is conflicting and making avast! going to this problem. Find and uninstall the other product :slight_smile:

I think your suggestion is preferable :slight_smile:

Run Hitman pro 3.6 and see if other rogue programs are in the system.
