Hi everyone,

 

Recently i have installed Bitdefender Total Security 2016, And noticed that internet browsing became very slow!, Like any page that used to "fully" load instantly or in 2 seconds, Now it would take about 15 seconds or more!, Also i noticed that the time windows take in the "Welcome" screen got way longer!, It used to be about 3 - 5 seconds now its' about 17 seconds, I'm aware that antivirus must have an impact on the performance in general, But not like that.. I googled it and found many people who've been facing the same issue, I tried almost everything mentioned in their topics and still having the same issue. So i was wondering if someone is familiar with that or know a way to fix it.

 

Things i tried and didn't fix the problem:

 

- Stopped firewall.

- Changed adapter settings.

- Disabled web protection module.

- Changed Router's DNS/PC DNS.

- Used Bitdefender removal tool/Re-downloaded/Re-installed/Repaired.

- Tried different browsers.

- http://www.bitdefender.com/support/my-internet-is-slow-1100.html

- Did a fresh windows installation!

 

 

Notes:

- Download speed is not affected.

- Websites that has SSL/HTTPS connection are slower than the ones who use the regular http/non-secure.

My small guess would be: SSL scanning is getting in the way. Disabling it might solve your issue.

Aura's answer would explain the browser slowness.

As for slower startup times...it may be taking longer for the full Internet Security Suite to load it's services and related modules. There could also be some type of pre-scan going on. Some anti-virus programs have a pre-scan for rootkits.

Can you try installing the Antivirus Plus version of BitDefender (the one with the least functionalities) to see if the start time is reduced? BD Total Security has a lot of features so it will take longer to load.

Thanks guys, After a couple of hours i managed to fix all of those issues i mentioned, and here is what i did to fix it (It may or may not help someone else in the future):

1- Downloaded the uninstall tool/Setup file.

2- After uninstalling was done, I restarted my PC and reinstalled it again.

3- Updated the engine.

4- Ran all scans: Quick Scan, Vulnerability Scan, System Scan.

5- Ran the Startup Optimizer: (Disabled everything but Bitdefender) and OneClick Optimizer: (Deleted all files).

6- Disabled "Block port scans in the network).

7- Adapters settings:

- Network Type is set to: (Home/Office).

- Stealth Mode: (Off).

- Generic: (On).

8- Turned off Scan SSL.

9- Deleted files in:

\AppData\Local\Temp

\Windows\Temp

\Windows\Prefetch

10- Restarted my PC.

Now everything is working smooth as it should :).

This is quite a lot to do just to get Bitdefender Total Security to work. The OOBE should be better but at least you got it to work, and that's what matters :)

Does Bitdefender Total Security install any plugin and/or extension in your web browser(s)? Which web browser(s) do you use? SSL scanning is still disabled?

Since you have to pay for Bitdefender Total Security, why not consider replacing it with Emsisoft Internet Security or just use Emsisoft Anti-Malware with Windows Firewall.

See my comments in Supplementing your Anti-Virus Program with Anti-Malware Tools as to why I recommend Emsisoft Anti-Malware.

If you want, before you uninstall it again, seeing that only Bitdefender is enabled on startup, I would configure a clean boot (which disables all third-party programs and services from loading on startup), restart the computer and see if your web browsers are still slow.

If they are, it means that Bitdefender Total Security is indeed the issue here (and I'm already pretty sure that it is).

Thanks for the suggestion mate, The thing is i already have 1 year license, So i thought i could make use of that :).

I think that Bitdefender is definitely the reason, Because every time i uninstall it while testing, things go smooth and run as it should to be.

If you already purchased one year of BDTS, can't you ask for a refund due to unsatisfactory experience? I would think a big company like BitDefender has such an option. Edit: BD does have a reputation for terrible customer support though.

In that case, it's good enough of a reason to change Antivirus software.

Sometimes you just have to cut your losses and move on.
