waaa.. i just discovered. I dont really use internet explorer. I always use Mozilla Firefox. how come the start page is youporn.com? and when i tried to check it thru internet explorer. i cant change it. is this one effect of the virus? sir/mam?

sir/ mam, i think the problem is with the scandals.exe in my c:\windows\system\ folder. i did some research and found that it is a threat. please help me remove this.. i cant open regedit and the taskmanager.

Your best option may be to try a ‘system restore’ point (if available) to a date before any known problems or before you started performing any recent fixes:

How to repair the operating system and how to restore the operating system configuration to an earlier point in time in Windows Vista




You may need to reset your YAHOO password or get a new account to avoid reinfection.

sir. i cant find my system restore. when i tried to search it via start >> start search, no matches were found...

sir! yes! i explored more and i found the system restore. now its back to normal! yeah! thank you so much...
Umm can i ask for suggestions as to what softwares should i install to get protected... please..
