I am running Avast Free with Windows XP SP3. As of yesterday my internet browsers can’t connect. I ran 4 different virus/trojan scans, 3 different malware/spyware scans, CCleaner and 2 other disk cleaners, 2 registry cleaners. Nothing worked.
I disabled the firewall and still couldn’t connect. I updated Avast and still couldn’t connect. I figured out that Outlook would let me online through it and thought that was weird. Used Outlook to search for solutions and tried a few but nothing worked. Only thing that will work is to disable the Avast Web Shield. I tried with and without my FW and it worked both ways.
After I got connected in IE I opened some websites and then enabled the web shield. I tried to refresh the websites and they couldn’t connect. Disable the web shield and they worked again by just clicking refresh. What’s going on! Is there anything that can be done or do I have to find another free antivirus program?
I just started having the same problem…Avast web shield blocking port 80…I have tried just about everything suggested on this forum…no luck…only solution seems to be to delete port 80 from troubleshoot / redirect page…or just disable the web shield. Strange thing is: some web sites open just fine with the web shield activated ( banking for example ) also email and Avast updates work fine. I have run scans with Malwarebytes Anti Malware, registry mechanic, and Avast of course…ALL coming up negative…Also I have run Ccleaner to delete any junk files. I think Avast 5.0.677 is awesome ( until this glitch arose ) I would like to keep it and NOT go back to AVG…hopefully a fix is in the works ! Any other ideas ??
BTW: this problem is not happening in my desktop computer…only my laptop seems to be affected. I am running XP SP3 with IE8 in both. I have tried switching to Firefox and re-installing Avast to no avail…I also tried bypassing the router and connecting the laptop directly to the modem…again…NO luck.
I have had this problem and it is not a problem with your AV, a system file has been deleted or unable to run.
But, the truth is I have forgotten how to re-enable it. After having this problem, I simply re-installed XP and everything was fine. I think that a virus damaged the computer while it was active and make that irreversible.
I always suggest a clean re-installation when you cannot connect to the internet due to the malfunction of a system file.
I got my web browsers connecting again after stopping the Web Shield. The problems reappear as soon as I enable it. I started having this problem today.
Ok, I ran the batch file for Windows 7… and it works now.
I don’t know why it malfunctioned. I did change user account type and modified UAC, but Avast had also updated the definition files and I had upgraded graphics card drivers, using driver sweeper. I reinstalled some apps. I did too many things to be able to tell which change broke it and later after a reboot I noticed I can’t access the web anymore.
Thank you PDAFREAK for your solution re: winsockfix…I downloaded and ran it …PROBLEM SOLVED…everything is back to normal !! Pass this on, a lot of people are having this problem…
