Today my computer engineer came . since problem had disappeared after restoring, he did nothing except to installing Hindi font and DVD player. after that previous problem was re occurring and also a suspicious site with blank pages is opening automatically . I again restored the system in yesterday’s date thereafter it is working.
Thereafter I installed avast . It scanned the files thoroughly and reported that c file is infected with win 32 trojen . It gave several options in which I pressed key for “delete all”. Now, the system is working with new problems : 1. reporting a malware 2. automatically
opening a suspicious site with blank pages .
Note : This thread also gives a picture as to how competent and honest computer professionals we have ! Aforesaid engineer belongs to broadband team and was recommended to me by BSNL authorities. So far my system is concerned, I bought it under assurance and belief that everything including windows is genuine.
