Kaspersky update interferes with internet access, anyone else ?

System: WIN XP SP 3 updated, trial/test version.

I've been testing KIS 2013 on a machine. I liked it for the most part and everything went fine till today.

After an update I could no longer use the internet !

It appeared to be a network or DNS error. Short pages would sometimes load, long ones would not or only partially. However, after extensive troubleshooting (including restoring an image of KIS which worked fine till the update) KIS itself turned out to be the problem. Needless to say, I removed and replaced it. For an AV, killing the computer is one of the worst things it can do.

Has anyone else experienced anything like this ?

 

Wellcome, check this problem in Kaspersky forum:

It seems, there was a temporal problem with updates yesterday.

Regards.

 

Thanks, but I'm not sure if it's quite the same.

I didn't have CPU issues.

Kaspersky will treat some anti-malware programs as tampering with the Windows hosts file, resulting in a false positive. Add the Windows hosts file to the Kaspersky exception list so the false positive won't be flagged in the future.

 

I'm glad KL got the issue fixed quickly as this wasn't the first time an update has caused issues (albeit the last incident was some time ago).
