Default SAS problem

Thanks guys,

Have downloaded and am using the Mac skin, much more attractive.

Just prior to getting rid of Avira the AV found 3 Trojans -as it was not scanning at the time I assume the resident shield did its job-so entering paranoid mode I ran MBAM and Avast They both found no other malware but as my PC was still running 'buggy' I also launched SAS, in quick scan mode it detected nothing but a full scan revealed yet another Trojan.

Today I am having the same problem after I launch SAS that occurred yesterday, in that I cannot close or minimise my browser window and all the icons in the task bar do not respond. The only way I can access SAS when it is minimised during a scan is by left clicking my mouse wheel.

Has anyone any ideas why this could be? Would I be right in thinking that Avast maybe having a conflict issue with SAS?

I've run Avast and SAS together for quite a long time.

I did, however, have many similar issues after deleting Avira. I had to actually do a registry search and delete all mentions of Avira before I quit having problems. I don't recall if Avira has an uninstall tool or not.

My suspicion is that this is a left-over Avira issue and not an Avast issue.

The is an Avira Personal Removal tool that should be used to clean your system of all remnants of the antivirus. The Removal Tool will clean your registry.

Download Avira Antivirus Registry Cleaner

Hi

I've come across similar issues after Avira has been un-installed, or rather not un-installed properly.

Open your task manager and see if any leftover Avira processes are still running.
Look for these:

avgnt.exe
avesvc.exe
avguard.exe

I've had instances where 'avguard.exe' still runs because Avira didn't un-install correctly. This can cause many issues with your system.

If you still have any of the above processes running it's best to re-install Avira and then un-install it again using Revo un-installer, use the 'advanced' removal option and clear everything *carefully*. Then run CCleaner.

After that run a search and delete any leftover Avira files you may find. Re-boot your machine and it should have cleared Avira from your system.

Avira can be very tough to get rid of.

This is why I've quit recommending Avira.

1) significant update issues, 2) a pain in the behind to uninstall or get rid of, 3) leftover remnants that cause problems with other security software.

I've not find an issue so far with any security software with Avast. (I should add that I have not uninstalled Avast, so I don't know if it has similar issues with uninstalling that Avira has.)

what you can do is enter safe mode,look in regedit and look for all avira's files and folders=DELETE IT...
-also whenever you find and kill a trojan,etc,,,empty your system restore.

That's a very unsafe recommendation. I advise that one's uses avira's registry cleaning tool and\or other removal tools as they do work better than anyone can do this by hand. The same goes for Avast is you ever need to unstiall avast..use there uninstall too are there will be no issues. I have uninstalled both Avast Home and Avira Personal more than several time on my client's machine and have never had a problem if the proper tools are used to do an uninstall and cleanup. If you do not use the tools designed for this, you are bound to have problems as Avast and Avira both generate a lot of registry entries.

Thanks guys for all your suggestions,

I used CCleaner to scan the registry and deleted the AntiVir Desktop key. I also used the Avira Registry Cleaner which showed up 182 keys! I was too worried about deleting them as they appeared to include keys for Iobit 360 and Avast.
I then updated MBAM and ran a full scan and this detected 2 more Trojans. After this I launched SAS which ran fine and there was no repeat of the earlier 'buggyness' or any sign of PC nasties.

I am presently running another full scan with MBAM, so fingers crossed!

My main concern is the fact that the fully updated Avast 4.8, set to thorough scan, completely failed to find all 6 Trojans.

As there is an a-squared offer on Nov 11th I may well be tempted. I guess it just goes to show the merits of layered security.

I guess it's possible. I've never had SAS or MWB find something other than cookies in 6 months or more of use of Avast. I find it hard to believe that Avast missed 6 trojans. Again, it is possible. But, I wonder if they were true trojans or false positives?

BTW--I do agree with multiple layers of security and even running SAS or MWB or A2 Squared as manual checks. It is just the smart thing to do.
