Hi Guys Having following problems notwithstanding running NOD32 on XP P4 machine: 1. Can't change homepage on internet options - goes to "about:blank" (tried CWS shredder without success); 2. Can't open task manager to close file winpack.exe that was causing problems logging on net. 3. In 2 above, everytime I get on explorer goes to a web address I enter for a few seconds and then reverts to "http:\\" with this screen duplicating until it stops (no internet access at all - running ADSL) 4. NOD32 has detected files like trojanhorse and rooter but problem persisting. Any help is greatly appreciated!!
