I am very sure (and hopeful) that someone here will be able to offer the solution. I have been reading posts here on the site for something very similar... i need some specific advice for my situation though please.
I had the same situation where pop-ups keep arising saying that i need to purchase anti-virus.spyware software etc. and also, the desktop has been taken over by a black image which says the same warning.
I deleted the security guard yesturday from the computer.. but obviously the effects are still there. If i trace the "location" of the present background image "file://C:\Windows\web\desktop.html" and then delete it.... i can get rid off the black warning image, but it is replaced by a grey/white image which flickers.
Now someone else posted the same thing on this site... but i have a slight problem, further than already discussed. I read the "solution" which was to untick all the boxes under "desktop", "customize desktop", "web"... but for me, i can't even access it!! It has hidden "desktop" from me so i cannot alter it. How do i get rid of it now??
Another thing i should mention, is that for this computer, there are different "user accounts"... my girlfriend, and mine, and a few other names (which aren't used). It was while using my login that the thing jumped onto the computer. It managed to get onto my girlfriends login too.... but that one has now been cleared by following the advice of unticking boxes.. because somehow, on her login, you can access the desktop, and change the background. For me though, as already stated, i cannot access the "desktop" function... what do i do?? how do i get rid of this hijacker? it is so frustrating.
Please help, and thankyou in advance.
