Glad to hear that you are enjoying your Dell. Yes, you should remove Trend Micro before installing another anti-virus.  I'm not sure which trial version of TMIS you have, though.

Here are some links that may help, depending on which version is installed:

I read some where that you should only use one internet security VP software on your pc for it to work it's best and not a combination of different brands of protection is that true?

Webroot is okay, but remember that there is no security that will protect you as well as the person sitting in the chair behind the computer. It's how you surf and where you surf to, and NO P2P (file sharing).  We do see infected systems that are using Webroot, but we see all others as well. You might want to read some reviews. I like this one: http://www.av-comparatives.org/  They test independently and without advance knowledge. Included in those tests is newly discovered malware as well as the WildList which is already known to the vendors. I don't see that Webroot was tested, though.

ky331 is away on vacation, but if you search this forum you will see that he and joe53 as well as a few other regulars here have some good suggestions on security programs and reviews.  Basically, I use Avast (Free),  Malwarebytes' Anti-Malware (Paid version, but there is also a free version without auto updating and realtime scanning), and WinPatrol (Paid, but there is a free version available). All three are from different vendors, and seem to do well together.

If you want to try the free software, please see these pages:

Thank You so much for very promptly helping me and all this information you've provided me with!

I'm enjoying my Dell so much! I wish i had made the switch sooner!

You're welcome. :emotion-1: 

I've got another question I need some help from, you guys are great!

I have an external hard drive and the files on it are from Media Player Classic K-lite codec pack. Does anyone know a link that is safe where I can get the K-lite codec pack ?

You might try here.

Hey. I'd really like to thank you again for your input and advice! I actually tried the Malwarebytes on my old pc that was having problems and i was amazed that it very quickly found the adware and removed it! I haven't used my Dell lately because my Trend Micro trial period expired and i have the links you gave me to uninstall the Trend Micro so i can install the Webroot I bought. 

I just had another question for you about this reply you wrote me:

Actually, if you are using anti-virus and anti-spyware from same company all you get are the malware definitions from that one company.  If you are using anti-virus from one vendor and anti-spyware from another you can have the best of both worlds.

That makes sense. But since the Webroot I bought is virus and spyware protection. can i install that and still use like the Malwarebytes? I was just curious to how you can combine them all like that and make sure that they are all working. i've only used the Norton VP in the past but am very disappointed with them! they don't seem to be as good as they once were. I got a trojan with Norton and adware! so I just want to make sure and protect my pc the best way i can. and i am going to take your advice about the file sharing!

thank you for all your sound advice!

If you are using thre free version of Malwarebytes' Anti-Malware, it is an on-demand scanner (does not run in real-time) and will not conflict with your Webroot AV/AS.

It is running 2 or more AVs in real-time that can cause conflicts, and probably the same can be said for 2 or more anti-spyware programs. But one can run as many on- demand scanners as you wish (although not at the same time!)

Thank you so much! that really did clarify what i was asking. so its when you run 2 or more in real time that can cause the conflict. ok So the free version of Malwarebytes should be fine with the Webroot.

i really do appreciate you helping! this forum is great!

thanks, i tried that site but wasn't able to find the right K-lite codec to work with my Media Player Classic:emotion-6: but i appreciate your help!

Hello:emotion-1:

I had another quick question.

since my pc runs with the windows vista and windows has the 'windows defender' and 'windows firewall', do those run in real-time?  thanks for all the help!
