However, when I turn on my computer today, it acted very wired, I can feel that my system run a bit more slowly, what’s worse, I can’t launch few of the programs, I mean I just bought this laptop two weeks ago, now what happened to it makes me very upset. My antivirus program cannot help me fix this problem, I don’t know why. Anyone who knows this Trojan, could you please help me?
Brief Introduction to Win32/trojan.2ff
Win32.Dofoil is a risky and pesky Trojan spread on the internet recently, like many other Trojan horses, it’s aim to attack computer system with Win 7, Win 8, vista, XP etc. Once installed, Win32.Dofoil could automatically open every time you turn on your computer by modifying registry entires. The most intuitive way for a victim to know this virus is that, his computer will be running slower and slower as time goes by, for example, when he watching a network video, each picture will stall about a second, it feels like watching in slow motion reply, that’s because the frame skip is abnormal due to the CPU usage was greatly taken up by this Trojan horse, even though he didn’t run many programs. After that, many other problems come into being, system performance is getting poor,you will get forever loading when open a website, some programs can’t run in a proper way or may even be unable to launch. I might say, this is not the worse, some innocent users found their system already crashed down, or they couldn’t log in their account at all!
Win32.Dofoil could make your recovery software out of run, so you cannot restore your operating system, that’s because it will create desktop_.ini in every file which mark the activation date, and delete all the expanded name with gho. Also, most file like *.exe、*.com、*.pif、*.src、*.html、*.asp will be infected, it’ll add virus url, so that when you try to open some website, it’ll redirect your to vicious one and many other malicious software may be downloaded and installed clandestinely without your permission, they could harm your computer system more or less. Well, this all happened after your computer was infected by Win32.Dofoil, the point is, why did people suffer from this virus in the first place? Actually, it is commonly bundled with free programs from third-party application which people barely know. Due to many different reasons, many victims are enticed to download freeware bundled with Win32.Dofoil. Such as, you’ll get a tip from pop-up window while you browsing some sites which say you need to upgrade your adobe player or other popular programs, some users may believe in that! And you may also become a victim by clicking some funny links from your emails, most of them are spams.
Anyway, it’s better for the victims to remove Win32.Dofoil right away, it’s base on how much value info and date in your computer, criminals always seek for vulnerabilities from victims’ computer, so they can control the systems at the greatest extent and take advantage from them. So, try to fix the problem as soon as possible if you unfortunaetely let your computer suffer from this virus!
