Today, a Rogue-Anti-virus infected my HP Slimline. It is secured with Avast! PRO Anti-virus. The rogue antivirus was named - “My Security Engine”. When I tried to access Avast! It was completely disabled. When I pressed “Fix Now” It wouldn’t turn on, the same with the “Real time Shields” It was all turned off. Luckily, I had one more Anti-Malware program. Malwarebytes Anti-Malware was able to detect and delete the rouge antivirus that somehow got on my computer and disabled Avast! Pro Anti–virus. The same is with a Trojandownloader:win32 appeared on my Dell Inspiron 1545 and Avast! PRO Antivirus was disabled. Again Malwarebytes Anti-Malware saved me. So WHY Does Avast! Get disabled and not turn on when I need it the most, when my computer is attacked?
What is the use of having Avast! Pro Anti-Virus when a virus just kills it?
just one question: what do mean by “somehow” ??? when you’re talking about the way the rogue got downloaded, you have absolutely no idea?
How Avast reacted is another question, and that’s unfortunately not the first time I hear that it doesn’t block rogues downloads and actions.
The thing is, I haven’t used that HP Slimline in a few months, I use my laptop 24/7. I just got on today to get all my pictures off onto a USB then out of no where this rouge starts installing. I used to play video games on that computer all the time, but I scanned mostly every file before opening. Thats not the issue at hand here. The issue is Avast! Anti-Virus PRO Does not work when I need it the most. The virus just turns it off and wont re-enable itself, even after pressing “fix now” or “start program”
The reason for the growth in numbers is what is known in technical terminology as ‘polymorphism', an old defence technique which involves changing the binary checksum of every copy (or download) of a piece of malware. This makes it much more difficult for antivirus programs to detect the programs.
I read that article, I get it a little more now. Infact, I just downloaded Superantispyware portable edition on my USB to use incase my computer gets infected again and I dont have MBAM.
The rouge program install when you download it and runs its installer. It can’t infect a computer from nothing. If you dont remember what you installed last time then that is other thing. Maybe someone that used it.
Just a question, are you using the 5.0 version of avast? Because avast is supposed to be resistant to malwares that tried to shut it down…
Maybe you got a window like this: http://help.artaro.eu/images/general/avastfree70.jpg and you clciked “Yes”, not knowing what it was otherwise if you’re using v5.0 and didn’t get thhe window then I think it should be checked out as something went wrong in the process…
