Removed Antivirus Number 1, but now no other antivirus program will install
Posted on 2009-04-06
Have a customer computer that became infected with one of the new trojans - antivirus number 1, while running AVG free version. I ran sdfix and then malwarebytes. The fake antivirus appears to have been taken care of, however, I tried to reinstall AVG and it failed. I ran the AVG remover and then tried again several times unsuccessfully. A few times it didn't fail on the install, but then it wouldn't run either (startup or manually). So, then I decided to try Avast. Avast started the install and then just quit. So, even though the customer really wanted something free, I decided to try Kaspersky (one of my favorites). It installed fine, but then won't run - even after a reboot. It doesn't run at start up and it doesn't run if you launch it manually. This leads me to think that the trojan isn't gone, but all of the information I've read for this particular one just says to use Malwarebytes. So, I ran Malwarebytes again, this time in safe mode and it didn't find anything. Thank you in advance.
