I am new to this forum but not to Comodo and computeras over all. I have the most remarkeble problem.
For like 4-5 months ago my Internet randomly shut down. Not in complete but it slowed down the connection speed to like 1kb/s or 1b/s. The Commodore 64 loaded faster (Bruce Lee on tape anyone? Stopped at 263 counters? And then U could get ?Load error. wellwell). No virus. No Trojan. Scanned with AVG, Malaware, Ad-awrae , SpyDoctor. Nothing. No harware failure (Connection indicated 100Mbit/s), no DNS error when I called them. Netstat works when internet is down. Neither MSN, browsing or email works. Its all dead. Soulution? System restore.
Ive searched the Internet for this problem and found simular problems but not exactlly this one. Now I have downloaded CIS and uninstalled AVG and hopefully this will get rid of the problem. But I have to ask you guys. WHAT is this problem??? Noone seem to know.
Reboot into normal mode and see if you find any remains of the virus
Download and install Hijackthis. Afterwards, do a system scan and safe a log file. A text file will open in notepad, safe this one and later upload it together with your post.
DO NOT FIX ANYTHING YET !!!
For a more exact troubleshoot we need a bit more details but assuming this is not caused by a “rootkit” and a spamrun or something similar, you could try the following things now, and compare them when things are bad…
ping your default gateway (use ipconfig /all to find it’s ip address).
This should give a stable result, if your on Copper it should respond between 1 and 3 ms.
then test if dns resolving works type:
And see if that resolves to an address.
Now ping that address on dns name, my response time is 10ms to www.ripe.net.
I knew someone here was going to think its funny. But, I can understand why!!
At my house, we had the internet come in and out(incuding phone service) for 8 months and at random times. After a long time trying to figure it out. One day, I decided to call the phone company. Apparently they were doing some major work in the area for a long time. But to keep the story short. They eventually finished it and problem solved. <–right before winter too. :o
WOW!!! Thanxx for all this reply. What knowledge outthere. I will defenetly follow your advice but forgive me if I not respond too quickly because I have much work right now but check in cause I will do this. Again, thanxx!
eXPerience. Comodo AntiVirus Qurantined the zlib.dll fiel which causes Botdefender to a non-run. Evenm if I restore the file I get a error message. I ran a online quickscan though with Bitdefender and it showed no results.
I will run Superanti and Malaware. Done that before and there is no show of malware. One question here is also if it WILL find anything while Internets running fine or if it will find something when it craches? I problbaly should do both huh?
I will do this, paste logs and the Hijack log here. I am sorry this takes time but I am choked right now but very thankful!

Now if you type ping forums.comodo.com and press enter it will look like this:
I will try that next time it happends. But the plot thickens. It happend yesterday. I booted in safe mode with network to see if I could connect to Internet. No such luck. Same problem. I then restarted in normal mode and voila: Internet now worked. Without me doing any systemrestore.
My computer told me when I tried to shut it down later that 8e4 didnt respond. I googled that with out any success.
Very intressting. I will really inspect this the next time the error occurs - 4 now I lost track of when it happend the last time and the systemlog is quiteful of information. But thanx again. it also fun to learn!
