Hello, my notebook was infected by a stupid malware, well, how stupid I thought it was real and checked with hirens BCD and all hardware seemed to be fine... no recently software installs, AV is Avira Internet Security 2012, database is up to date... So, symptoms were: 1.Empty start menu(it was disabled, except turn off/log off buttons). 2.Empty desktop, sometimes black sometimes grey wallpaper.(it disabled desktop) 3.Disabled task manager. 4.a lot of messages saying that my hardware seems to fail by software called "system restore", if you look at the photo in lower left corner you'll see button "press to buy". 5.and of course, all files were hidden, so my docs, and local disk's were empty... it also reported that my hard drive is full... it actually had 3gb out of 40gb. So be aware of that malware! I'm attaching screen shots I made. Virus is 2 .exe files located in All Users/App Data and boot entry. No fresh software installations were made. So, I deleted virus, but still encountering few problems: 1. skype goes off(process gets killed after 10s it gets connected). 2. sometimes receiving "Write file delayed in windows". I have scanned PC with AV, no viruses at all. and checked AV with keygen, it detected it I still have one virus process saved in PC, but I zipped it.
