I'm a long time "lurker" of this site and have found many helpful pointers in regards to my pc security over the years. So thank you. I decided to take the "plunge" and sign up to post after experiencing a strange issue with one of my computers. Here goes: I recently downloaded and installed Bullguard Internet Security as a trial to determine if I wanted to purchase the product. As a disclaimer, prior to installing Bullguard, I had Comodo Internet Security installed and honestly I didn't have any issues with it whatsoever, but I wanted to try something that was "rated" higher. (I know that is a relative term, of course.) So I installed Bullguard on my pc and one thing that I noticed was that the scan seemed to be less memory intensive and faster than a scan with Comodo, other than that everything was running silky smooth and I was going to make the purchase once the trial expired. Here is where my issues came in. Well, I'm somewhat a Youtube junkie and love listening and watching commentary and videos in my free time. One day as I was listening to Youtube I noticed that my sound wasn't quite right, as a matter, of fact it sounded horrible--so much so that I began to think my speakers were in disrepair. I went to other sites with videos and the same thing! I could, however, watch videos, that weren't being streaming from the internet without issues i.e. a home movie. My laptop is less than a year old and I've never had this issue before. I checked to make sure my drivers were up-to-date, checked for malware, etc., anything that I could think of. The only thing that was different on this pc was Bullguard, so I uninstalled it, and my sound returned to normal! It was very odd. I've tried to duplicate the issue, but I have not been able to do so. I installed Webroot's Security Anywhere after seeing the reviews and great sale on it and haven't looked back. But I'm still curious as to the cause and if anyone else has had a similar experience? Thank you in advance for your response. And I apologize for the lengthy post.
