My subscription to Trend Micro expired so I decided to try a free anti virus program. After doing some research I decided that Avast was probably my best choice. I downloaded and updated it and after doing so I started a full scan then went to bed. The next day I started having problems connecting to the internet. I couldn't get web pages to load in any browser. I tried Chrome, Firefox, and Internet Explorer same problem with each one. Other programs connecting to the internet did not have any issues, including online games, and voice chat programs.
I disabled Avast and the connection issues were resolved. I then removed avast and downloaded AVG and the exact same problem occurred with AVG.
I don't have any idea what could cause this kind of thing. I didn't have any issues with Trend Micro.
My laptop is running Windows Vista 64 bit
I uninstalled Trend before I installed Avast.
I uninstalled Avast before I installed AVG.
I really would like to use Avast if anyone can help me resolve this problem...

I have the same issue and I don't know what to do. I had a full connection, updated my AVAST 4.8 Pro and lost my connection.
Can anyone help please...

Did you use a removal tool after uninstalling each? It would be best to run their respective removal tool to eliminate all possible remnants that could interfere/conflict with the next AV to be installed.
What firewall do you use? Do you have any antivirus running alongside avast/AVG/TrendMicro?

I didn't use any kind of removal tool, just selected uninstall from the programs and features in the control panel.
I have zone alarm firewall.
Not running any other Virus protection software.

Removal Tools:
(1) avast! Uninstall Utility
http://www.avast.com/eng/avast-uninstall-utility.html
(2) AVG Remover
http://www.avg.com/download-tools
(3) Trend Micro / PCCillin
http://www.support.antivirus.co.uk/trendmicro/kbresolution.jsp?hmid=2530&serviceId=1
Use them before installing another AV.

I think I may have also used McAfee at some point in the past, is there one for it as well?

Note: If use of removal tools does not work, the problem might be caused by viruses.
-
Well if it is a Virus neither Avast nor AVG found it...
>_<
-
So how are things going now? Did it work?
-
I'm trying the Trend Micro removal tool, but it doesn't seem to be working, I still have a lot of Trend Micro Files in my Program Files(x86)

Try working on it in Safe Mode (http://www.computerhope.com/issues/chsafe.htm).

What can i do if I can't access safe mode because the avast scan page wont budge or let me do anything. I can't even turn the thing off no matter how much I turn the pc off or turn it off and own.
-
avast! Scan page? Did you mean boot time scan? You may press ESC to bypass boot time scan.
Regarding safe mode, just restart your PC then, at the very first screen that'll appear, hold f8 until a selection window is presented. From there choose Safe Mode. Then select Windows XP. Then there you go. Just select Yes on the next pop up asking you if you are sure to boot into safe mode.

I am actually facing the same issues as you have, on a laptop, running vista (32-bit) with zonealarm and avast free edition.After a while, when I try opening a webpage in my browser, I get "website found, waiting for reply" in the left below corner , and the browser isnt going anywhere.When I started stopping the avast services (after killing nearly every other service and firewalls),I noticed that the problem got resolved when I stopped the avast webshield service. A temporary workaround for me was to install a tool named fiddler,a browser debugger, which allows you to launch an iexplorer from within the tool, and this works without issues, even when at the same time iexplorer does not work directly.
best regards,
G.

Make sure avast WebShield is allowed to access the Internet in Zone Alarm.

I wonder if Zone Alarm is the culprit here. I have always removed previous AV software from Add/Remove programs and it has worked fine. I have heard conflicting reports on using the additional uninstallers: Some techs say only use them if you have having problems using conventional Add/Remove Program processes and others have said use the uninstallers regardless.
What about using your built in Windows Firewall and uninstalling Zone Alarm? Have you also tried using Avast's Repair Diagnostic tool? This is in Control Panel and when you click on Add/Remove Programs, scroll down to REPAIR. This will attempt to repair and replace damaged files in Avast. It has worked well for me.
If Zone Alarm is not the issue, have you also tried disconnecting your modem/router for several minutes? You may also want to try flushing the DNS cache before plugging your router or modem back in. Don't know how to do it on Vista, but for XP, close up any browser and other Windows you have open. Next do this:
Start - Run
- cmd - OK
ipconfig /flushdns
Try it; it won't hurt.
You might also want to the Run box type "temp" (no quotes) and delete all files in the temp folder. (Edit/Select All/Delete.)
Also Go to My Computer, Right Click on your Hard Drive (usually C), select Properties, and run Disk Cleanup. Say yes to the prompt
Now empty the Recycle Bin
Reboot your computer
After all the icons are on the screen, give it a minute or so. Now plug your modem/router back in and allow it 2 minutes to reactivate.
Can you browse with stuff like IE and Firefox now? During this time, (if you have accepted the default of Avast updating the definitions database automatically, about a minute after rebooting, you should get a Virus Database Has Been Updated message.)
My guess is this is a Zone Alarm conflict, or your modem or router had a brain fart and needs to be unplugged for a few minutes to get the bad data out. (reset.)
I hope the clean up stuff helps!

Zone Alarm and Avast don't get along very good with out some tlc on your part ,check your privacy setting in Zone Alarm that's whats probably blocking your access Also give Avast top level in trust and access to internet with Zone Alarm .If privacy controls for your browsers are set too high ,some web sites will not load.
