For the last few days I have been noticing something unusual. Normally, with each update the the total number of definitions for malware etc. goes on increasing. In my case few days back the total number of malware was 33 lakhs plus . Nowadays, with each update the total number is going down and now it is 3280139 only. Anybody else noticed it and if so, what may the reason? Or can it it be due to my pc being infested?
