Why does mse slow down computer

Windows Defender cannot be uninstalled from Vista or Windows 7. ID drop Norton in a heartbeat if it were up to me. That software is a huge resource hog and in my opinion, doesnt do as good a job as some of the free stuff out there. To answer your question defender and MSE are unrelated. One is a piece of garbage and the other is a pile of garbage. Personally I would strongly go against using them in a business environment. Though on the other hand for the consumer side MSE is ok and Defender is a little weak over all.

It is the most resource intensive anti-virus software I'v seen in the last decade! To continue this discussion, please ask a new question.

Hello, Recently I installed Microsoft Security Essentials on a computer, and since then it has been running very slowly.

Thank you. Best Answer. Paddy Oct 6, at UTC. View this "Best Answer" in the replies below ». If you feel that MSE slows down computer, check out the system requirements and see if they match your computer configuration. MSE slows down computer if your computer does not meet the minimum system requirements and some other reasons. If your computer does not match the above specifications, MSE will slow down the computer. You may opt to continue using MSE or replace it with any other antimalware.

If you wish to continue with MSE, the next section explains how the exclusion of some folders will speed up computer without adding additional risk. Another reason why MSE slows down a computer is the presence of other antispyware on the computer.

Was explorer being used for copying or moving files during the slowdown? Anonymous Inactive. HTWingNut , Sep 12, I have said it many times but noone believes, MSE is one of the worst antivirus programs out there!

Yes it is light on resources but it sucks big time in protection! I have had 2 viruses crawl twice on to my system even though I am a safe user.

LOL To everyone running MSE I advice you to run a scan with another AV god knows how many viruses you might be having and not even knowing it Look at MSE's results down at the bottom: One time while I visited my mom's place, my sister was telling me that her laptop keeps having these popups from the AV.

So I checked and she had MSE installed telling her that she has a few viruses, which upon checking, I know they are false positives which I verified on virustotal. Stuff like a utility that can display your WLAN password or another that can tell you what product keys you have installed.

So I let MSE delete them when it prompted me for an action and thought oh well she doesn't need them anyway they were from my Software folder which I copy to all our computers in the family. MSE firstly had a lot of False positives, and more importantly, it couldn't even delete those harmless false positives!

So not only does that test I posted by a professional virus testing organization stands true, I have also had experience with this piece of crap. Want another reason why it's crap? All AVs update silently in the background but for me on Windows 8, the updates come as a Windows update!!!
