Trojans are usually not so dangerous, but they are a pest. BUT IF YOU USUALLY BUY THROUG INTERNET, YOU NEED TO UPDATE
EVERYDAY YOUR COMPUTER
1.- You need a powerful antivirus AND antispyware. For my computers I use Norton.
2.- ACTIVATE YOUR FIREWALL. Some programs and sites in internet, in order to work, need you to disarm your defenses.
AFTER USING THEM, REMEMBER TO ABLE YOUR FIREWALL AGAIN.
3.- If the problem persist, maybe you'll need to take your computer to the technichian IN ORDER TO MAKE A DEEP
CLEANSING -READ: FORMAT YOUR HARDISCK AND INSTALLATE AGAIN YOUR PROGRAMS, AND FOR THIS YOU'LL NEED TO BACKUP YOUR
DOCUMENTS AND OTHER STUFF IN CD's OR DVD's- Deep cleansing is different to a normal format, but you have to
ask the thechnichian.
4.- LOCATE WHERE YOU HAVE BEEN THAT COULD HAVE DOWNLOADED THE TROJANS.
