Avast! keeps blocking a "malicious url"

[UKilledKenny26]

Every so often, Avast! will give me a message saying
"Malicious URL BLOCKED avast! network shield has blocked a harmful site"
The "malicious url" is like a bazillion characters long and made up of random letters, and under "process:" in the window is usually a file under c:\users\owener\appdata\local
The thing is, this message appears even when i'm not on the internet, and would happen with my old antivirus as well. When i had the old antivirus (symantec), it would list an ip adress rather than a url, which i would block, but a few minutes later i'd get the same message just from a slightly different ip. Is there any way to make this url stop "attacking" my computer for good?

@UKilledKenny26,

I don't know if this will completely solve your problem, but it is worth anyway.

Since you say that this was happening with your previous antivirus too, have you uninstalled it (and rebooted)? After uninstalling your old antivirus, you should run the respective specific removal utility. The removal utility would find remnants and this would reduce potential conflicts. A partial list of removal utilities is located at http://singularlabs.com/uninstallers/security-software/. Look for the specific tool you used to have, read the info and follow the instructions to run the adequate removal utility.

Whether it would solve the problem or not, I don't know, but removing remnants of older security tools is always recommended.
 
Please report back.
