"Really disappointing"

June 27, 2011  |  By texmw

 |  Version: BitDefender Antivirus 2011

Pros

Not sure there are any, I guess it's protecting me

Cons

Slows computers to a crawl

Summary

I had BD 2009 and BD2010, ran like a charm. Then I installed BD2011 Pro, what a mistake. Have it on three computers, two with XP, one with Vista, they all run extremely slowly now. Most times I get an error message.
Now I know those ratings don't mean a thing, this has been a real disappointment. I'm not a techy, so I don't know all the reasons, but this has been a waste of money for me.

"GARBAGE - Why is this getting Editors Choice awards?"

June 14, 2011  |  By jkoerner

 |  Version: BitDefender Antivirus 2011

Pros

???Pros??? Ha, ha ha ha ha! What a joke! is that supposed to be a joke? There are NONE - no pros at all in this total P.o.S.

Cons

ZERO SUPPORT - I have submitted at least 20 requests for support, in various ways - and have not gotten ONE single response from them.
CPU HOG - periodically for no apparent reason, starts hogging enormous chunks of CPU time, making PC unusable.

Summary

Why is this getting 5-star ratings from places like MAXIMUM PC? Do they not even install this crap? Are they being bribed? On drugs? Inconceivable that anyone could give positive reviews of this utter garbage.

"DAILY FRUSTRATION!!!!!"

June 02, 2011  |  By jsonntag

 |  Version: BitDefender Antivirus 2011

Pros

none none none

Cons

a daily PAIN IN THE ASS, ! it ether doesn't start up real time protection, or warns that a scan hasn't has been (which it has)

Tech supports says to TURN OFF USER ACCOUNT CONTROL!! unfortunately, that's how I know that BItDefender is not running!!!

Summary

STAY AWAY!!! product quirky with Windows 7, tech support insists on giving wrong answers, or turning off the very tool that WARNS ME Bitdefender is not running!!!!!!!!!

"BitDefender Review - Really not good enough"

June 02, 2011  |  By imorgs

 |  Version: BitDefender Antivirus 2011

Pros

Very easy to set up, simple interface and pretty customisable with handy game mode feature. Good virus protection.

Cons

Woeful customer service
Very slow and resource hungry.
Slows down machine performance significantly.
New releases and updates always buggy.
Eats Virtual Memory
Causes regular intermittent freezing of all web browsers disrupting normal use.

Summary

I am now on my third BD incarnation starting with 2009 which was great, 2010 which, upon release was a nightmare but settled down after a couple of months and 2011 which has been a nightmare. The releases are clearly poorly tested and buggy as the BD Forums attest. Which would be ok-ish if their customer service support was up to scratch but frankly it is woeful.
Everything is managed by email, response time (if you get one) can be two weeks or more and their solutions appear to be to progressively switch off more and more modules until all you have left is a skeleton system, then to suggest a reinstall and finally to abandon you and ignore you.
I am a patient man, not quick to judge, but after three years of progressively worse products and being treated with contempt by this company, my business is going elsewhere. I strongly suggest you do the same.

"Regrets!!! Pure crap!!! I am so pisssed"

May 20, 2011  |  By Nasia29

 |  Version: BitDefender Antivirus 2011

Pros

slow scan, my scan is always interupted by a pop-up message. unable to detect threats, cause computer crash, I lost some programs. lack of support, i was ignored by bitdefender support

Cons

I would not recomannd anyone to download this software. It is pure junk. I have lost of regrets

Summary

I purchase bitdender from the website after i did some research about the top virus protection form 2011. I was excited to download because a good price. I am so pissed and sick of this software it caused my computer to run very slow. I never had a Virus protection software that run so slow before, and after waiting hours for the scanning to be over it is always interupted by a pop-up message. I contact support for help and they made me uninstall some software off my computer, but that didnt help much and my computer was still in trouble. I try to get some more help and they completely ignore my message. Now i have to pay a repair guy to take off a virus that attacked my computer recently.I can't open most programs on my compter. I have to take bitdefender off my computer before the year is up. It was a waste of money and time.

"Going back to Avast Pro..this is Crapware"

May 05, 2011  |  By Danne_Mannen

 |  Version: BitDefender Antivirus 2011

Pros

It passed VB100% several times

Cons

Terrible performance and slow scans

Summary

I was looking forward to tryout Bitdefender beacuse i read nice things about it..and now im so disappointed

Updated on Jul 25, 2011

Bitdefender has one of the larges databases in the world and its really an effective guard..but the things that is most anoying is that it slows down the PC pretty much. On-access scanner is really slow..
Process vsserv.exe sometimes hog 100% CPU for no reasons

To make it better..They need to listen more to what the users say.
After all..its the users who use it

"One of the worst antivirus out there other than norton"

 |  Version: BitDefender Antivirus 2011

One of the worst antivirus out there other than norton and mcafee. Keeps crashing and freezing up the computer and usually have to restart the computer to fix it and completely uninstall it and install avast antivirus

Summary

INSTALL AVAST ANTIVIRUS!

"totally ineffective"

March 04, 2011  |  By trkd

 |  Version: BitDefender Antivirus 2011

Pros

looks nice

Cons

3 well known virus attacks went right through it like it wasn't working resulting in hours of reconstruction. Support said I would get a reply within 48 hours(long time) and it took a week. In the interim I solved my own problems.

Summary

totally worthless software. Microsoft Internet Security is way better and is free-this is from a Microsoft hater! I would not buy this product and if it was free would not use it. You will be sorry if you do-that's my bottom line.

"Terrible tech support, incompatible with ZA firewall"

February 24, 2011  |  By g_phillips

 |  Version: BitDefender Antivirus 2011

Pros

low priced

Cons

Is incompatible with other security solutions installed. Results in system instability, IE locking up and slow operation. A scan will simply delete infected files without telling you which files were deleted and what the infection was.

Summary

Is hard to understand why BD 2011 gets excellent reviews, as I run into nothing but problems, and as a result have half of my software which has to be reinstalled because files were deleted. Tech support: at least 2 weeks go get a meaningless answer.
