First the facts: I was on GBA temp forums which i know don't contain viruses, i am running McAfee security centre, with windows firewall off as it clashes and i and using an account which is not an administrator account on Vista Home Premium x64 bit. I noticed the little yellow triangle a bit like this in the taskbar; i've seen it before somthing to do with windows sercurity. So clicked it and it came up with this 'Disk repair' program which i immediately knew was a virus as i've seen similar things before Warning: Spoilers inside! It came up with some scanning thing at the bottom and then came up with all these critical error and other crap (see above) . i tried closing it and it stayed as another icon in the taskbar. I've just opened task manager and managed to end process to both the triangle and the disk repair and am currently running a malwarebytes anti-malware full scan. I also notice that on my desktop there is an icon for the program (which is in the screenshot) and it has a link in my start menu, neither of which were there about half an hour ago; and i havn't even typed in the administrator password today so i shouldn't havn't been able to install anything. I haven't downloaded anything dodgy recently and i can't understand how it got past my mcafee and installed itself without me knowing. One thing though, i have recently been using chrome instead of ie as it has been crashing recently so i have no mcafee site advisor bar. Also, a few give aways that it is a virus: > It has a blue and yellow shield for 'run defragmentation' which i know is windows 7, not vista. > It has not got very crisp, sharp images for the links on the tabs and help and support etc. > It also, on right click of taskbar icon, came up with: Minimize/restore Diagnostics Run defragmentation Setting Help support Buy Now! > the minimize in bold and being at the top and the buy now! and the two spaces between help & support are all giveaways. So: >Is it a virus? >How did i get it? >Why wasn't it picked up by Mcafee? >How should i remove it? P.S. NVgT5Kv7Y6tq.exe *32 is it's image name in task manager. P.P.S There is an 'Uninstall Disk Repair' exe in the taskbar folder but i don't trust that. EDIT: i've also noticed, cleverly, it has disguised itself as windows' disk defragmentator which does actually defragmentate your system.
