Help! Sad

I am running Windows Vista Home Premium with McAfee Antivirus

I got a virus on my PC yesterday: the "Antivirus Vista 2010". McAfee managed to remove it (well 'quarantine' it anyway) but following the removal various things are not working properly - including System Restore!

Some of my desktop icons when click show Application not Found. For all but two application icons I have tried (including System Restore, Disk Cleanup etc) I get the Open With dialogue box, which is of course inappropriate for an application.

I cannot even open the McAfee Security Centre. But Internet Explorer and Windows Mail seem to be working OK and I am also able to open my data files.

It is worrying that I can open neither System Restore nor the McAfee centre.

I'd be very grateful for suggestions.

If you can see the files in your system restore, google them to see what they are. Every now and then antivirus software can delete what is known as " false positives" these can be proper files but the software thinks they are a virus. This may not be the case though. Can you get into safe mode?

Sounds like McAfee did, not do a great job of removing it, as it does disable things like you AV program and restore function.

This page might be of help.

Personally I would use this as a good excuse to get rid of Vista and do a clean install of Win 7.

I can't get into system restore at all. I just get the Open With dialogue box when attempting to start it. Can I get to see the files in another way?

I think I know how to get into safe mode (hold down F8 while booting?) but I've never done it - and not sure what to do once I've done it.

McAfee quarantined two files when removing the virus. I suspect one of them should not have been disabled but there is no quarantine folder and I can't open McAfee either!

See here it's tricky to remove.

The actual virus is no longer a problem (well seemingly not - the symptoms have gone) but its removal seems to have created the issues I have mentioned.

keep pressing F8 until safe mode appears. It will grey the screen icons but should (will) allow you into the control panel.

Start/Control Panel/ System - haven't got Vista but you should find your restore points somewhere there. Perhaps Macafee has a restore point too?

Good luck

Have you tried running a repair install (assuming you have the disk to do it)?

Quote: Malwarebytes Anti-Malware is definitely worth a shot. I've seen it rescue systems from that kind of virus.

I'll second that - only thing that worked on my machines.

Well thank you guys - much appreciated. I knew I could rely on EPZ's IT expertise! Smile

What I did was start the PC from a recovery disk - starting in safe mode did not work properly.

I managed to get into System Restore via the disk..... but had a couple of moments of panic (Grin) when it (a) said the system restore wizard was already running! and (b) once it stopped saying that, it refused to restore to the immediately previous point - an error message was generated saying some file was missing. But, thankfully, I managed to get it to restore to the point before that (early-December).

I then had to re-update McAfee as that, although now accessible, it was saying I was not protected.

I really do not want this sort of thing to happen again!

So........ am I right in reading the above as suggesting I should ditch McAfee and install Malwarebytes as my AV?

I should add that I also have SpyNoMore which is (paid) anti-malware software, which I occasionally use to scan my drives.

A friend of mine has an identical PC and OS and uses AVG, which seems to have been effective. Is this an alternative?

I think I'm right in saying its a removal tool rather than prevention one so I think you should also use another AV program.

I've used AVG for years without any problems so I continue to stick with it, but others might disagree that its the best option. Avast also seems to be a popular choice these days

Malawarebytes is not an anti virus programme

SpyNoMore was at one time on the rogue tool list. It is still considered dubious by some see here for example

OK, so something like AVG + Malawarebytes could be a better combination than my current McAfee + SpyNoMore?

I run the full version of AVG and had no problems until last week. A friend of mine suggested running Malwarebytes which immediately picked up the culprit. It seems there is no one program that will cover all bases. He runs Malwarebytes once a week along with AVG free software plus Spybot. I concur about moving up to Windows 7 by the way.
