Hi, after update to Free Avast 7.1 blocks Paint Shop Pro 9 (not X9 but 9) running on Windows XP
switching off Avast (10 minutes, 1 hour, etc. doesnt help)
The process Paint ShopPro is visible in Task Manager window
the only way to run Paint ShopPro 9 again is to uninstalling Avast 7 or to install previous version of Avast
any ideas ?
greetings,Piotr
Erm, are you really talking about V7…!? ???
you avast too old , please upgrade to latest version 
I pretty sure avast has stopped supporting v8 and earlier. So v7.xxx is out of luck. Best thing to do is upgrade.
My bet is that it is a typo and piotrzyk means 17.1
A clue is that there never was a version 7.1

TRUE 
sry
Found a old copy of PsP 9 (having a decent administration about what is on what cd/dvd really helps HaHaHa) and installed on W10 with avast 17.1.2286 latest build and it works without a problem.
Disable shields in avast one at a time and see if one of them is causing the problem.
I am still using Paint Shop Pro 9 quite often and have no trouble whatsoever in combination with Avast 17 (or any Avast version for that matter).
On what OS Doc ?
I have same problem. Avast is blocking not only Paint Shop Pro v9, but also and other Paint Shop Pro versions like X6. Disabling avast or even running windows in Safe mode does not help too. The only solution is to uninstall avast. After uninstall, program runs normally. I have newest Avast version and Windows 7 32 bit. I have this problem on two different PCs.
I have the same problem with Gimp–Avast blocks opening the program, plus (if I momentarily disable protection and turn it back on), it blocks opening any files). Disabling Avast solves this, as does disable the Behavior Shield. But of course this leaves me vulnerable.
I reported the issue to Avast and they sent back a message saying that they can’t find a record of my account in their system, even though I’ve been using Avast for many years!

Same problem with the brand new V17.2.2288 under Windows Vista.
I had to uninstall Avast to solve the problem :-[
Disabling just the behavior could be enough.
Try Settings>Components>Behavior Shield>Customize>Exclusions, then browse to the program on the C drive and add it. I did this with programs like Sketchup and it worked. I still haven’t solved the Avast blockage of all Windows applications and there is no response from Avast about the issue.
Same Problem here, Windows 7 32bit
Avast 17.2.2288 (build 17.2.3419.59) is blocking Paint Shop Pro 9 AND Paint Shop Pro XI
Adding exceptions to File System Shield AND Behavior Shield did NOT help!
Uninstalling the new Avast version and reverting back to an older version FIXED the problem, but as soon as I allowed Avast to update to the new version again, the problem returned!
All other programs I tried appear to be unaffected by this, and ONLY Paint Shop Pro (both old Jasc and newer Corel version) are being blocked by Avast
We are talking about the NEWEST version of Avast (17.2.2288) that is causing a problem and blocking Paint Shop Pro 9
We are talking about Paint Shop Pro v9 AND NEWER versions. For me it is blocking Paint Shop Pro 9 (Jasc Software) AND Paint Shop Pro XI (Corel Software).
BOTH worked perfectly in the previous version of Avast, but stopped yesterday after I upgraded Avast to v 17.2.2288 (build 17.2.3419.59)
Uninstalling the new Avast version and reverting back to an older version FIXED the problem, but when I allowed Avast to update its program version again, the problem recurred. Disabling File Shield and/or Behavior Shield (or any other shields) DID NOT fix it, and neither did adding exclusions to any of the shields.
If you read the responses to your quote of Para-Noid, you will see that because of the version typo by the OP Para-Noid believed he was using avast version 7(being unsupported), nothing to do with the version for Paint Shop Pro.
I also reported the Problem (in my case with PaintShop Pro 9 AND PaintShop Pro XI to Avast and they replied
