Try this free active X On-line Spyware Scan
it may remove it for you. Worth a try
I notified Panda on the virus alert from Avast (which I also got when trying to use Panda, and I even sent them a screenshot of the virus warning)and they blew me off saying I wasn't a paid customer so they wouldn't help me...sounds like a false positive alert to get you to buy their product which after how they treated me they can stick it!

Haha....funny thing is, doing a google search, panda looks like the only one with removal...go figure.

Hopefully Jabuck will ask you for a HJT log and then you'll get that thing fixed....looks pretty nasty to me.


Hopefully my advice will help you...Please post back with your results....thanks

Jabuck followed instructions and doesnt seem to have cleared. I have pasted in the 2 logs below. Thanks

DSE I will try manual.

Worringly I thought I would give the automatic removal a go on the link, it showed 30 infections....

Will try manual removal and see where it takes me, and post back. Any further advice greatly appreciated.

Have been also posting in and looking in Malware Forum. Appears that running some anti malware guards can cause a false positive in MS Anti Spyware. Have looked into this and could be the case? Have tried loads of scanners/AV/Trojan and none are showing anything.

If this is the case I have boobed as I started following the manual removal guide suggested above. Deleted wscntfy.exe (as this associated with the Rivarts.a Have since found it is a legitimate SP2 file.

PC seems ok apart from MS Spyware scan wont now intialise....

Would be really grateful if Jabuck, you could give me your view on the possibility of this false positive.

Here is link to the post I refer to:

It could very well be a fp, I never was a MSAS fan. I use spywareblaster. Either way Rivarts.A is a subtle foe and can cause you a lot of grief.

I would first try to run the Panda scan again or Kaspersky it is underlined in orange on this page.

You may be able to temporaraliy turn off real time protection for any of these programs you have and get the scanners to run by following the directions at this link Turn off real time protection

The pcpitstop scanner at this link is Panda so try running it http://www.pcpitstop.com/antivirus/default.asp and post the results. If the scanner is like Panda to save the scan results click the See Report button, then Save Report and save it to the desktop, then copy/paste into the text editor and post it. Otherwise you will have to look for it

Also run the Kaspersky scan and post the results.

1. Read the Requirements and Privacy statement, then select "Accept"

2. A dialogue box will appearing asking "Do you want to install this software?" Name: kavwebscan_unicode.cab

3. Select "Install" to download the ActiveX controls that allows ActiveScan to run.

4. If running MSAS beta you may receive an alert that an IE ActiveX program requires your approval. Click "Allow"

5. When the download is complete it will say ready, click "Next"

6. Click "Scan Settings" and check the option to use the EXTENDED DATABASE, then click "OK"

7. Select a target to scan: Click on "My Computer"

8. When the scan is complete choose to save the results as "Save as Text"

Thanks Jabuck.

Last night I checked my other networked PC (Lan). A week or so ago I had installed Trojan Hunter. Also MS ASpyware has been on it for a while, hadnt scanned since putting on Hunter. Got the same results for Rivarts. This morning uninstalled Hunter, did a CCleaner Reg clean. Ran MS ASpyware.....came up clear of Rivarts. so looking very much like a false positive.

I have run the Kaperski and Pitstop scans. Did them yesterday and both clear. The Panda one despite installing Active X and stopping Avast would not run. Figure it might be something with security settings (will turn of MSAS real time protection and also Hunter) although all the other online scans I tried seemed to work ok with no positives.

Will try that now and post back.

With Panda Turned off all real time protection I have. Activex etc started to download but then came up with an error. Referred generically to possible causes(connection/permissions).

After clear Kaperski yesterday along with the FP on the Lan connected PC am I safe in assuming a MSAS "conflict" with Trojan Hunter?

Or should I try further to get Panda scan working?

I had nearly identical scan results that you did with MSAS. On a hunch I found that Symantec calls this PWSteal.Rivarts not Rivarts.A So I uninstall my AV program and installed the Norton's AV trial ware, which I really didn't want to do, but I wanted to get rid of this thing bad enough that I didn't care it was NAV. I had to run the scan in safe mode because the program froze in normal mode. It found a file called Adware.Linkmaker which I deleted. I ran MSAS again and finally no Rivarts.A! Oh, removing Trojan Hunter did not work. Try this and good luck!
