I've got an issue with my PC which I fear might be some form of dangerous infection and was hoping for some assistance as the problem has got progressively worse. The following was the situation about 6 months ago - I asked about some help then but didn't get any responses however I decided my computer was just about useable enough that, provided I didn't do any banking/e-mails etc from my home PC I'd be ok as I'd managed to use basic AV software to get some of the issues out (see below):-

Copied from previous post

"I've been using Google Chrome as my default web browser for a while as frankly, I'm not mad keen on IE. I powered up my computer and clicked on the Chrome shortcut from my desktop only to get the following message:-

'Windows cannot find C:\Program Files....\Google\Chrome.exe. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.'

I searched for the file and it definitely exists within the directory for which the shortcut references. I even tried double clicking on the program logo directly from the source directory and got the same error message.

I thought it was probably just a bugged out bit of software or that the shortcut link had somehow messed up so uninstalled and then attempted to reinstall Chrome via Internet Explorer. The install shows as successful but the same error message occurs when I try to launch Chrome. I dug a little deeper and the problem also extends to Firefox and to Safari. The Firefox launcher shows a slightly different error message but the same basic problem arises.

So, I went to browsing with IE for a while as I needed to look some stuff up for work and I noticed periodically I壇 search for something via Google (or any other search engine) and upon clicking on a search result it would take me to a different website.

I rebooted my PC to see if things would go away (the IT helpdesk at work always tells me to reboot if I致e got a problem!) although I know enough about IT that I知 fairly sure thats not going to solve my problems. In fact, it actually makes things worse/identifies a new problem as upon start-up I get the following error message:-

"The application or dll 舛:\......\vbuvfy.dll is not a valid windows image. Please check this against your installation diskette."

I知 pretty certain at this point that I must have some (or more) malware on my PC so I tried to clean things up a little. I did a little digging around and downloaded some additonal anti-virus software (Kaspersky and Hitman Pro 3.5) which have managed to deal with the vbuvfy.dll trojan and the browser redirect issues respectively. Neither of these pieces of software have identified any further issues and I知 still having the same problem in respect of Chrome/Firefox etc.

I知 now wondering whether I知 still infected or whether the Chrome issue is something more innocent (I知 suspecting the former). Any help would be hugely appreciated. Thanks!"

Rolling forwards 6 months my computer is now suffering even more. In addition to still not being able to use non-IE browser software, I'm now having issues with IE which make it pretty unusable. Periodically after I've clicked a link from Google it will instead redirect me to a different web page. Additionally, IE crashes frequently. It will crash out and attempt to recover pages every time I open multiple tabs (usually unsuccessfully) and it will crash every time I attempt to download files/software from IE (I was actually trying to download some new free AV software and it would crash as I did so - I think in future I'll have to download the exe files to a memory stick from a different computer and then upload to the main one.

As before, any help would be hugely appreciated. Many thanks!
