Kaspersky Anti-virus and Internet Security users have started reporting since about a few hours that their desktop security software is blocking access to Google domain under the classification of ‘Suspicious URL'.
Users have turned to Kaspersky's forum to report this particular bizarre behaviour by their security software. It seems, based on the posts made by users, that the particular issue is only affecting the Indian sub-continent as of now.
"I am using Kaspersky Internet Security 2011. All my databases are up-to-date. Only a few minutes back, I had been surfing the net perfectly well. All of a sudden, Kaspersky showed Google as blocked because of malicious url", stated a user.
Another user stated, "Same issue(issue reported as above) I am facing now; Using KIS 2012 here."
Orkut, Google's social network that is quite famous in India, is also getting blocked reported one user. "I'm using Firefox 8. ... Update: Even its blocking orkut.co.in also!"
It seems that a buggy update might be the reason behind such behaviour, but there has been no confirmation from Kaspersky in this regards.
We have contacted Kaspersky and awaiting an update so stay tuned.
