I am infected with backdoor.teideserv!inf. My Symantac virus software cannot clean or quarantine it. The specific file name infected is C:Windows/system32/drivers/iaStor.sys. Also, everytime I use google search engine it redirects me to a bogus site and sometimes back to Google itself. I had the machine to a tech guy and he could not figure how to get rid of this. Worst of all everytime I attempt to go into safe mode I get a blue screen message. My computer is about 5 years old, is a Dell with xp professional. I am probably considered a newbie but am willing to do what it takes to rid this bug from my computer. Anyone can help I would appreciate it.
